中英文对照资料外文翻译文献 打包机 打包机是一种农业机械,它用于压缩已切割和倾斜的作物(如草、稻草或青贮饲料)成易于处理、运输和储存的小包。常用的打包机有几个不同类型,分别生产不同类型的包-矩形的、圆柱形的,大小各不相同,用麻绳、网或金属丝缠绕起来。工业打包机还可以用在材料回收设备上,主要用于包装需要运输的金属、塑料或纸。 圆形打包机 在工业化国家最常用的打包机是这种又大又圆的打包机。它生产圆柱状的“圆”或“筒状”的包。草在打包机内被捲起,使用橡胶带、固定滚筒,或两者的组合。当包达到规定尺寸时,用网或麻绳裹住它,以保持其固有的形状。打包机的后面打开,包被排出。包在这个阶段完成,但也可以用塑料薄膜包裹,当在室外储存时能保持干草的干燥或者将潮湿的草变成青贮饲料。可变仓打包机通常生产直径为48至72英寸(120~ 180厘米)、宽达60英寸(150厘米)的包。无论在任何地区,这些包可以重达1100至2200磅(500 -1000公斤),包的重量取决于大小,材料,和水分含量。 最初,圆形打包机的构思由Ummo Luebbens于大约1910年提出,第一台圆形打包机才生产出来,一直到1947年Allis-Chalmers 引进了旋转打包机之后。由于它的干草包脱水干燥和重量轻的特点从而得以推向市场,到1960年生产结束时,AC已经销售了近70000台 接下来的一个重大创新是在1972年,当时Vermeer公司开始出售其型号为605的第一台现代圆形打包机。以前,圆的干草包仅仅是干草缚在一起的肿块,但Vermeer设计使用皮带将干草紧密结合起来形成一个圆柱体,正如今天所看到的样子。 大型矩形打包机 另一种常用类型的打包机生产大型的矩形包,每个包缠绕半打左右的麻绳,然后再打结。这样的包非常紧凑,重量又普遍比圆形的包大几分。在加拿大的草原,它们被称为草原猛禽。 小型矩形打包机 这种打包机现今是不常见的,但在许多国家却是相当流行,如新西兰和澳大利亚,除了大型包的生产,还生产小型矩形 (通常被称为“正方形的”) 包。每个包大约是15英寸 x 18英寸 x 40英寸(40 x 45 x 100厘米)。这种包是用二股、三股、或有时四股麻绳捆绑。这种包非常的轻,一人就能举起,大小约45至60英寸(1.1到1.5米)。 为了形成捆包,料堆中需要打包的原料 (经常干草或稻草)被打包机捡拾器的齿举起。然后这些原料被拖进或钻进一个长达打包机一个边长的打捆室内。活塞和刀在打捆室的前端来回地移动。刀恰好在活塞的前面,它可以当场切断从捡拾器进入打捆室内的原料。活塞将这些原料向后推移,压缩成捆包。一个测量装置测量被压缩的原料的数量,并在适当的长度,触发捆绑麻绳并且将其打结的机械装置(打结器)来捆绑包装并将其打结。当下一个捆包加工成型时,这个打结完的捆包就从打捆室的后面排出到地上或推送到一个用钩固定在打包机后 部的特殊的货车上。只要有原料需要打包,并且有麻绳来捆绑包装,这一过程就会一直连续进行。 这种形状的捆包不太适用于大规模商业性农业,因为处理许多小捆的成本比较高。然而在一些小规模,低机械化的农业和养马业享有一些名气。除了使用简单的机械设备及容易处理外,这些小包也可用来绝缘和当作草捆建筑中的建筑材料。正方形捆包一般也会比圆捆包要好,因为他们可以更密集地堆放在一起。 便利也是农民决定继续使用正方形包的一个主要因素,因为它们使得饲养和在狭窄的地方(马厩,仓库等)堆放容易得多。 这些旧式打包机,现如今在农场还有许多可以找得到,特别是在干旱地区,在那里,捆包可以长期在室外储存。 小型方捆自动打包机成型于1940年。它首先是由New Holland Ag生产制造的,并采用了小型汽油发动机提供运行动力。它是基于1937年一个具有自动拾取功能的麻绳打结打包机发明创造出来的。 线材打包机 在1937年以前,捆包是用两股包装线材人工包裹的。甚至在更早以前,打包机是一个固定的打包设备,由动力输出装置(PTO)和传送带驱动。干草被加进打包机处并人工用手塞进去。自1940年之后,这种打包机最大的改变是通过动力输出装置(PTO)由拖拉机驱动,而不是通过内置式内燃机。 在目前的生产中,人们可以选择使用麻绳打结器或者是金属丝缠绕打结器的小型方捆打包机。 捡拾和处理方法 在20世纪40年代,大多数农民将会使用一辆20马力甚至更小马力的小型拖拉机在田地里捆干草,并且当打包机从田地里走过时,捆绑包将会掉落在地上。另一组工人驱使马拉着平板货车从旁边走过来。他们用尖锐的金属钩来钩起捆绑包,并把它们扔到平板货车上,同时另外一个助手好这些捆绑包,以便运输到谷仓。 后来,一个节约时间的发明是直接将平板拖车接在打包机之后,这样草捆包就可以顺着舷梯推送给马车上的助手。等待在马车上的助手用钩子钩住草捆包,从舷梯上移开,并在马车上摞好,同时等待下一个生产好的草捆包。 最后,随着拖拉机马力的增大,抛掷打包机就成为了可能。抛掷打包机消除了需要有人站到马车上来捡起草捆包。第一个投掷机械使用了两个快速移动的粗糙传送带来抓取草捆包,并把它们以一个角度向上抛起落到马车上。马车是由平板车改造成的前端开口的三角架,以此来充当捕捉抛出的草捆包的网。 随着拖拉机马力的进一步增大,抛掷打包机的下一代更新产品是液压投掷打包机。这种打包机在包打结器的后面采用了一个平板。当打好的草捆包从打包机的后面出来时,它们依次被推送到平板上。当草捆包完全移动到平板上时,在一个大型液压缸的推动下,平板就会突然自动弹起,将草捆包抛掷到马车上,就像弹射器一样。 这种平板投掷方法与传动带投掷方法相比,大大减少了施加在草捆包上的压力。在抓取并投掷草捆包时,传送带投掷运输机的粗糙的 传送带给予草捆包的捆带绳结很大摩擦力,并且有时在投掷运输机上或者是草捆包降落到马车上时,会导致草捆包的破损。 纽荷兰发明了一种新的机器命名为堆垛机。小型方包从打包机中出来后,捆绳朝外,堆垛机将开到草捆包处,将他们捡拾起并放在相当于三个草捆包宽的桌子上(现在草捆包的捆绳朝上)。当三个草捆包放到桌上时,桌子就会被举起,并后退,造成三个草捆包再次捆绳朝向一侧;这种情况再接着发生三次,直到有16个草捆包放在主桌上。之后,主桌就会像小桌子一样抬起,使草捆包正对一个垂直的桌子。这种机器可以装160个草捆包(10层),通常靠近中心的部位会有交叉层叠,以免再有重量加到草垛顶上时,草垛会摇晃,不稳定,甚至坍塌。之后满载的堆垛机会被运送到谷仓,堆垛机的整个后部会倾斜向上,直到垂直。当堆垛机离开谷仓时,从机器延伸出的两个推动助手会扶着草垛的底部,把草垛从堆垛机上移出。 在英国,如果小型方包仍在使用,那么当它们从打包机出来后,它们通常是被收集到跟在打包机后的一个草捆包雪橇上。这种雪橇有4个通道,由自动机械天平,挂钩和弹簧控制,每一个通道划分容纳八个草捆包。当雪橇装满后,挂钩会自动弹起,后面的门就会打开,把这八个草捆包整齐的放在地上。之后这些草捆包也许会人工一个个拾起,或者人们用拖拉机上的草捆包抓取工具,将这八个草捆包一起拾起。这种草捆包抓取工具是一种特殊的安置在拖拉机前端的装货机,含有许多液压驱动的向下弯曲的长钉。之后,这些草捆包要么堆垛在拖车上运走,要么在田地里堆砌成8层或10层高的立方体草垛。 然后这个立方体草垛由更大的机器运走。这种机器连接在拖拉机后,可以夹住草垛侧面,将其整体托起运走。 处理大型和小型圆形草捆包的一个简单的方法可以在文章《Hay Delivery》(《干草递送》)中看到。相对于拖拉机而言,这是一种仅仅自己动手的改进。两个挂钩被焊接到拖拉机前端装载机的顶端,还有一个14英尺(4.3米)的日志链,它可以使用户呆在拖拉机上来抓取草捆包,运输,堆砌以及再把草捆包放在外面喂养动物。形成一条龙作业。这个简单的操作系统的优点是它不必使用昂贵的设备,也不用在拖拉机上来回交换应用这些工具。这使得小农户避免了额外器械的花销,不用仅仅因为这样一个功能而另买一台拖拉机。通过一些小练习,人们就可以和专业的液压捆包抓取机一样,快速的拾取草捆包。由糖山农场(Sugar Mountain Farm)的沃尔特•杰弗里斯(Walter Jeffries)改进的这种方法同样只需要较少的维修养护,并且比包矛和钳子更安全。 Baler A baler is a piece of farm machinery used to compress a cut and raked crop (such as hay, straw, or silage) into compact bales that are easy to handle, transport and store. Several different types of balers are commonly used, each producing a different type of bales – rectangular or cylindrical, of various sizes, bound with twine, netting, or wire. Industrial balers are also used in material recycling facilities, primarily for baling metal, plastic, or paper for transport. Round baler The most frequently used type of baler in industrialized countries is the large round baler. It produces cylinder-shaped "round" or "rolled" bales. Grass is rolled up inside the baler using rubberized belts, fixed rollers, or a combination of the two. When the bale reaches a predetermined size, either netting or twine is wrapped around it to hold its shape. The back of the baler swings open, and the bale is discharged. The bales are complete at this stage, but they may also be wrapped in plastic sheeting by a bale wrapper, either to keep hay dry when stored outside or convert damp grass into silage. Variable-chamber balers typically produce bales from 48 to 72 inches (120 to 180 cm) in diameter and up to 60 inches (150 cm) in width. The bales can weigh anywhere from 1,100 to 2,200 pounds (500 to 1,000 kg), depending upon size, material, and

工业机器人发展中英文资料外文翻译文献The development of industrial robotsIndustrial robot is a robot, it consists of a CaoZuoJi. Controller. Servo drive system and detection sensor device composition, it is a kind of humanoid operating automatic control, can repeat programming, can finish all kinds of assignments in three difficulties in authorship space the electromechanical integration automation production equipment, especially suitable for many varieties, become batch flexible production. It to stabilize and improve the product quality, raise efficiency in production, improve working conditions of the rapid renewal plays an extremely important role.Widely used industrial robots can gradually improve working conditions, stronger and controllable production capacity, speed up product updating and upgrading. Improve production efficiency and guarantee the quality of its products, eliminate dull work, save labor, provide a safe working environment, reduces the labor intensity, and reduce labor risk, improve the machine tool, reduce the workload and reduce process production time and inventory, enhance the competitiveness of enterprises.As technology advances, the development of industrial robot, the process can be divided into three generations -- generation, for demonstration reproduce, and it mainly consists of robot hand controller and demonstration teaching machines composed, can press advance box to record information guide action, the current industry repeated reappearance application of execution most. The second to feel robot, such as powerful sleep touch and vision, it has for some outside information feedback adjustment ability, currently has entered the application stage. Third generation of intelligent robot it has sense and understanding ability, in the external environment for the working environment changed circumstances, can also successfully complete the task, it is still in the experimental research phase.The United States is the birthplace of the robot, as early as in 1961, America's ConsolidedControlCorp and AMF companies developed the first practical demonstration emersion robot. After 40 years of development,the United States in the world of robotics has been in the lead position. Still Its technology comprehensive, advanced, adaptability is strong.Japan imported from America in 1967, the first robot in 1976 later, with the rapid development of the microelectronics and the market demand has increased dramatically, Japan was labor significant deficiencies in enterprise, industrial robots by "savior"'s welcome, make its Japanese industrial robots get fast development, the number of now whether robots or robot densities are top of the world, known as the "robot kingdom," said. The robot introduced from Germany time than Britain and Sweden about late 1956, but the Labour shortages caused by war, national technical level is higher social environment, but for the development and application of industrial robot provides favorable conditions. In addition, in Germany, for some dangerous prescribed, poisonous or harmful jobs, robot instead of ordinary people to the labor. This is the use of robots exploit a wide range of markets, and promote the development of the industrial robot technology. At present, the German industrial robots total of the world, which only behind to Japan.The French government has been more important robot technology, and through a series of research program, support established a complete science and technology system, make the development of the French robot smoothly. In government organization project, pay special attention to the robot research based technique, the focus is on the application research on in robot. And by industry support the development application and development of work, both supplement each other, make robots in France enterprises develop rapidly and popularize and make France in the international industrial machine with indispensable if position.British jamie since the late 1970s, promote and implement a department measures listed support the development of policies and make robots British industrial robots than today's robot powers started to early, and once in Japan has made the early brilliance. However, at this time the government for industrial robots implemented the constraining errors. This mistake in Britain dust, the robot industry in Western Europe was almost in the bottom of it. In recent years, Italy, Sweden, Spain, Finland, Denmark and other countries because of its own domestic robots market in great demand, development at a very fast pace. At present, the international on industrial robot company mainly divided into Japanese and European series. In AnChuan of Japanese are mainly the ethical products, the oTC, panasonic, FANLUC, not two more, etc. The products of the company kawasaki The main Asiatic KUKA, German CLOOS, Sweden's ABB, Italy CO work pelatiah U and Austria GM company.Industrial robot in China started in early 1970s, after 30 years development, roughly experienced three stages: in the 1970s and 1980s budding transplanter and the application of the 1990s initialization period. With the 20th century 70's world technology rapid development, the application of industrial robots in world created a climax, in this context, our country in 1972 start developing their industrial robots. Enter after the 1980s, with the further reform and opening, in high technology waves pound, our research and development of robot technology from the government's attention and support, "during the seventh state funds, thanked the parts were set robot and research, completed demonstration emersion type industrial robot complete technology development, developed spray paint, welding, arc welding and handling robot. , the national high technology research and development program begin to carry out, after several years research and made a large number of scientific research. Successfully developed a batch of special robot.From 9O 2O century since the early, China's national economy achieve two fundamental period of transformation into a a new round of economic restructuring and technological progress, China's industrial robots upsurge in practice and have made strides, and have developed spot welding, welding, assembling, paint, cutting, handling, palletizing etc various USES of industrial robot, and implement a batch of robot application engineering, formed a batch of industrial robots for our country industrialization base, the industrial robot soar laid a foundation. But compared with the developed countries, China also has the very big disparity of industrial robots.Along with the development of industrial robot depth and the breadth and raise the level of robot, industrial robots are has been applied in many fields. From the traditional automobile manufacturing sector to the manufacturing extensions. Such as mining robots, building robots and hydropower system used for maintenance robots, etc. In defense of military, medicine and health, food processing and life service areas such as the application of industrial robots will be more and more. The manufacturing of automobiles is a technology and capital intensive industry, is also the most widely used of industrial robots, accounting for almost to the industry for more than half of the industrial robots. In China, the industrial robot first is also used in automobile and engineering machinery industries. In car production of industrial robot is a major in the equipment, the brake parts and whole production of arc welding, spot welding, painting, handling, glue, stamping process used in large amounts. Our country is forecast to rise period, entered the automobile ownership in the next few years, car will still growing at around 15 percent annually. So the next few years the industrial robot demand willshow high growth trend, about 50% in growth, industrial robots in our automobile industry application will get a rapid development.Industrial robot in addition to the wide application of in the automotive industry in electronic, food processing, nonmetal processing, daily consumer goods and wood furniture processing industries for industrial robots demand is growing rapidly. In Asia, 2005 72,600 sets, installation industrial robots, compared with 2004 grew by 40%, and application in electronic industry accounted for about 31%. In Europe, according to statistics, since 2004 and 2005 in l: tI industry robot in the food processing industry increased 17% the application of left and right sides, in the application of nonmetal processing industry increased 20%, and daily necessities in consumption industries increased by 32% in wood furniture processing industry, up 18% or so. Industrial robot in oil has a wide application in, such as sea oil drilling, oil platforms, pipeline detection, refinery, large oil tank and tank welding etc all can use robots to complete. In the next few years, sensing technology, laser technology, engineering network technology will be widely used in industrial robots work areas, these technologies can cause the industrial robot application more efficient, high quality, lower cost. It is predicted that future robots will in medical and health care, biological technology and industry, education, relief, ocean exploitation, machine maintenance, transportation and agriculture and aquatic products applied field.In China, the industrial robot market share are mostly foreign industrial robots enterprise holds. Before the gunman in the international, domestic industrial robots enterprise facing great pressure of competition. Now China is from a "manufacturing power" to "manufacturing power forward," Chinese manufacturing industry faces and the international community, participate in the international division of labor in the great challenge of industrial automation increase immediate, government must can increase the funds for robots and policy support, will give the industry of industrial robots development into new momentum. With independent brand "devil robot" MoShi special technology company dedicated to providing solutions to the mainboard and robot, is willing with all my colleagues a build domestic industrial robot happy tomorrow!ReferencesElectronic Measurement and Intrumenttations,Cambridge University Press,1996工业机器人的发展工业机器人是机器人的一种,它由操作机.控制器.伺服驱动系统和检测传感器装置构成,是一种仿人操作自动控制,可重复编程,能在三难空间完成各种作业的机电一体化的自动化生产设备,特别适合于多品种,变批量柔性生产。

中英文对照外文翻译文献(文档含英文原文和中文翻译)By integration of machinery developmentThe modern science and technology unceasing development, impelled different discipline intersecting enormously with the seepage, has caused the project domain technological revolution and the transformation, in mechanical engineering domain, because the microelectronic technology and the computer technology rapid development and forms to the mechanical industry seepage the integration of machinery, caused the mechanical industry the technical structure, the product organization, the function and the constitution, the production method and the management system has had the huge change, caused the industrial production to enter into “the integration of machinery” by “the machinery electrification” for the characteristic development phase.First, the integration of machinery outlineIntegration of machinery is refers in the organization new owner function, the power function, in the information processing functio n and the control function introduces the electronic technology, u nifies the system the mechanism and the computerization design and the software which constitutes always to call.Integration of machinery is refers in the organization new owner function, the power function, in the information processing functio n and the control function introduces the electronic technology, u nifies the system the mechanism and the computerization design and the software which constitutes always to call.The integration of machinery development also has become one to h ave until now own system new discipline, not only develops along with the science and technology, but also entrusts with the new content, but its basic characteristic may summarize is: The inte gration of machinery is embarks from the system viewpoint, synthes is community technologies and so on utilization mechanical technolo gy, microelectronic technology, automatic control technology, compute r technology, information technology, sensing observation and contro l technology, electric power electronic technology, connection techn ology, information conversion technology as well as software progra mming technology, according to the system function goal and the o ptimized organization goal, reasonable disposition and the layout v arious functions unit, in multi-purpose, high grade, redundant reli able, in the low energy consumption significance realize the speci fic function value, and causes the overall system optimization the systems engineering technology, from this produces function system , then becomes an integration of machinery systematic or the inte gration of machinery product.Therefore, “the integration of machinery”covering “the technolog y”and “the product”two aspects, only are, the integration of machinery technology is based on the above community technology organic fusion one kind of comprehensive technology, but is not m echanical technical, the microelectronic technology as well as othe r new technical simple combination, pieces together, this is the integration of machinery and the machinery adds the machinery elec trification which the electricity forms in the concept basic diffe rence, the mechanical engineering technology has the merely technic al to develop the machinery electrification, still was the traditi onal machinery, its main function still was replaces with the enl argement physical strength, after but developed the integration of machinery, micro electron installment eliminated may substitute fo r certain mechanical parts original Outside function, but also can entrust with many new functions, like the automatic detection, t he automatic reduction information, demonstrate the record, the aut omatic control and the control automatic diagnosis and the protect ion automatically and so on, not only namely the integration of machinery product is human's hand and body extending, human's sens e organ and the brains look, has the intellectualized characteristic is the integration of machinery and the machinery electrificati on distinguishes in the function essence.Second, the integration of machinery development conditionIntegration of machinery development may divide into 3 stages roug hly, 20th century 60's before for the first stage, this stage is called the initial stage, in this time, the people determination not on own initiative uses the electronic technology the prelimi nary achievement to consummate the mechanical product the performan ce, specially in Second World War period, the war has stimulated the mechanical product and the electronic technology union, these mechanical and electrical union military technology, postwar trans fers civilly, to the postwar economical restoration positive functi on, has developed and the development at that time generally spea king also is at the spontaneous condition, because at that time the electronic technology development not yet achieved certainly Le vel. Mechanical technical and electronic technology union also not impossible widespread and thorough development, already developed the product was also unable to promote massively.The 20th century 70~80 ages for the second stage, may be called the vigorous development stage, this time, the computer technology, the control technology, the communication development, has laid the technology base for the integration of machinery development, large-scale, ultra large scale integrated circuit and microcomputer swift and violent development, has provided the full material base for the integration of machinery development, this time characteristic is:①A mechatronics word first generally is accepted in Japan, probably obtains the quite widespread acknowledgment to 1980s last stages in the worldwide scale;②The integration of machinery technology and the product obtained the enormous development;③The various countries start to the integration of machinery technology and the product give the very big attention and the support. 1990s later periods, started the integration of machinery technology the new stage which makes great strides forward to the intelle ctualized direction, the integration of machinery enters the thorou gh development time, on the one hand, optics, the communication a nd so on entered the integration of machinery, processes the tech nology also zhan to appear tiny in the integration of machinery the foot, appeared the light integration of machinery and the micro integration of machinery and so on the new branch; On the ot her hand to the integration of machinery system modelling design, the analysis and the integrated method, the integration of machi nery discipline system and the trend of development has all condu cted the thorough research, simultaneously, because domains and soon artificial intelligence technology, neural network technology a nd optical fiber technology obtain the huge progress, opened the development vast world for the integration of machinery technology,these research, will urge the integration of machinery further t o establish the integrity the foundation and forms the integrity gradually the scientific system.Third, the integration of machinery trend of developmentIntegration of machinery is the collection machinery, the electron, optics, the control, the computer, the information and so on th e multi-disciplinary overlapping syntheses, its development and the progress rely on and promote the correlation technology developme nt and the progress, therefore, the integration of machinery main development direction is as follows:3.1IntellectualizedIntellectualization is a 21st century integration of machinery tech nological development important development direction, the artificial intelligence obtains day by day in the integration of machinery constructor's research takes, the robot and the numerical control engine bed intellectualization is the important application, here said “the intellectualization”is to the machine behavior descr iption, is in the control theory foundation, the absorption artifi cial intelligence, the operations research, the computer science, t he fuzzy mathematics, the psychology, the physiology and the chaos dynamics and so on the new thought, the new method, simulate t he human intelligence, enable it to have abilities and so on j udgment inference, logical thinking, independent decision-making, obt ains the higher control goal in order to, indeed, enable the int egration of machinery product to have With the human identical in telligence, is not impossible, also is nonessential, but, the high performance, the high speed microprocessor enable the integration of machinery product to have .preliminary intelligent or human's partial intelligences, then is completely possible and essential.3.2 ModularModulations are one item important and the arduous project, becaus e the integration of machinery product type and the manufacturer are many, but the development and the development have standard m echanical connection, electrical connection, power connection, the e nvironment connection integration of machinery product unit are an item extremely complex also are the extremely important matters, like the development collection deceleration, the intelligent velo city modulation, the electrical machinery in a body power unit, h ave function and so on vision, imagery processing, recognition and range finder control units, as well as each kind can complete the model operation the mechanism, like this, may use the standar d unit to develop the new product rapidly, simultaneously also ma y expand the scale of production, this need formulation Each standard, in order to various parts, the unit match and the connecti on, as a result of the conflicts of interest, very will be diff icult to formulate international or the domestic this aspect stand ard in the near future, but might through set up some big enter prises to8 form gradually, obviously, the advantage which from the el ectrical product standardization, the seriation will bring may af firm, regardless of will be to produces the standard integration of machinery unit the enterprise to produce the integration of ma chinery product the enterprise, the formalization will give the in tegration of machinery enterprise to bring the happy future3.3 Network1990s, the computer technology and so on the prominent achievement was the networking, networking starting with the rapid developmen t for the science and technology, the industrial production, polit ical, the military, the education magnanimous act person daily l ife has all brought the huge transformation, each kind of network the global economy, the production linked up into a single stre tch, enterprise's competition will also globalize, once the integra tion of machinery new product developed, so long as its function were original, the quality was reliable, very quick could the b est-selling whole world, as a result of the network popularization , was on the rise based on network each kind of long-distance c ontrol and the surveillance technology, but long-distance control t erminal device itself will be the integration of machinery product , the field busWas the domestic electric appliances network has9 become the situation with the local area network technolog y, connected using the family network each kind of domestic elect ric appliances take the computer as the central computer integrati on electrical appliances system, caused the people at home to sha re the inconvenience and the joy which each kind of high-tech br ought, therefore, the integration of machinery product faced the n etwork direction to develop without doubt.3.4 MicrominiaturizedMicrominiaturization emerge in the end of 1980s, refers is the in tegration of machinery to the miniature machine and the microscopi c domain development tendency, overseas name it micro electron mec hanical system (MEMS), makes a general reference the geometry size not to surpass 1cm3 the integration of machinery product, and t o micron, the nanometer level development, the micro integration o f machinery product volume small, consumes energy few, the movemen t is nimble, in aspects and so on biological medical service, mi litary, information has the incomparable superiority, the micro int egration of machinery development bottleneck lies in the micro mechanical technology, the micro integration of machinery product proc essing uses the fine processing technology, namely ultra precise t echnology, it including photoetching technology and etching technolo gy two kinds.3.5 GreenIndustries lived developed for the people have brought the huge c hange, on the one hand, the material was rich, the life was com fortable; On the other hand, the resources reduce, the ecological environment receives the serious pollution, therefore, the people appealed the protection environment resources, the return nature, the green product concept arises at the historic moment under t his kind of call, the green is the time tendency, the green pro duct in its design, the manufacture, the use and in the destruct ion life process, conforms to the specific environmental protection and the human health request, harmless or the harm are extremel y few to the ecological environment, the resources use factor is extremely high, the design green integration of machinery product , has the broad development future, the integration of machinery product green mainly is refers, when use does not pollute the ec ological environment, after the abandonment can recycle the use. 3.6 systematizationsOne of systematized performance characteristics is the system archi tecture further uses open style and the patternizing main line st ructure. the system may the nimble configuration, carries on tailo rs and the combination willfully, simultaneously seeks realizes the multi-subsystem coordination control and the synthesis management, second performance is the correspondence function big enhancement, generally besides RS232, but also will have RS485, the DCS pers onification, the future integration of machinery even more pays gr eat attention to the product and human's relations, the integratio n of machinery personification will have two meanings, one will b e, the integration of machinery product finally user will be a h uman, how will entrust with the integration of machinery product person's intelligence, the emotion, the human nature appears more and more importantly, specially the opposite partyWith the robot, its high-level boundary is the man-machine integration, another imi tates the biological mechanism, develops each kind of mechanical a nd electrical body flower product, in fact, many integration of m achinery products all are developed animal's inspiration.Fourth, the model integration of machinery productIntegration of machinery product subsystem (complete machine) and t he foundation Yuan, the part two big kinds, the typical integrati on of machinery system includes: The numerical control engine bed, the robot, the automobile computerization product,12 the intellectualized instrument measuring appliance, the elec tronic publishing printing system, the CAD/CAM system and so on, the typical integration of machinery Yuan, the part includes: Elec tric power electronic device and equipment, programmable controller, fuzzy controller, miniature electrical machinery, sensor, special-p urpose integrated circuit, servo and so on, these model integratio n of machinery product technical present situation, trend of devel opment, market prospect analysis omitting.Fifth, our country develops the situation and the duty integration of machinery work which “The integration of machinery” faces mainly includes two levels: One, with the microelectronic technology transformation tradition industry, its goal is the energy conservation, the nodal wood, enhances the work efficiency, improves the product quality, enhances the traditional industry technology advancement one step;

Introduction modern science and technology unceasing development, impelled different discipline intersecting enormously with the seepage, has caused the project domain technological revolution and the transformation .In mechanical engineering domain, because the microelectronic technology and the computer technology rapid development and forms to the mechanical industry seepage the integration of machinery, caused the mechanical industry the technical structure, the product organization, the function and the constitution, the production method and the management system has had the huge change, caused the industrial production to enter into "the integration of machinery" by "the machinery electrification" for the characteristic development phase.1. Integration of machinery outline integration of machinery is refers in the organization new owner function, the power function, in the information processing function and the control function introduces the electronic technology, unifies the system the mechanism and the computerization design and the software which constitutes always to call. The integration of machinery development also has become one to have until now own system new discipline, not only develops along with the science and technology, but also entrusts with the new content .But its basic characteristic may summarize is: The integration of machinery isembarks from the system viewpoint, synthesis community technologies and so on utilization mechanical technology, microelectronic technology, automatic control technology, computer technology, information technology, sensing observation and control technology, electric power electronic technology, connection technology, information conversion technology as well as software programming technology, according to the system function goal and the optimized organization goal, reasonable disposition and the layout various functions unit, in multi-purpose, high grade, redundant reliable, in the low energy consumption significance realize the specific function value, and causes the overall system optimization the systems engineering technology .From this produces functional system, then becomes an integration of machinery systematic or the integration of machinery product. Therefore, "integration of machinery" covering "technology" and "product" two aspects .Only is, the integration of machinery technology is based on the above community technology organic fusion one kind of comprehensive technology, but is not mechanical technical, the microelectronic technology as well as other new technical simple combination, pieces together .This is the integration of machinery and the machinery adds the machinery electrification which the electricity forms in the concept basic difference .The mechanical engineering technology has the merely technical to develop the machinery electrification, still was the traditional machinery, its main function still was replaces with the enlargement physical strength .But after develops the integration of machinery, micro electron installment besides may substitute for certain mechanical parts the original function, but also can entrust with many new functions, like the automatic detection, the automatic reduction information, demonstrate the record, the automatic control and the control automatic diagnosis and the protection automatically and so on .Not only namely the integration of machinery product is human's hand and body extending, human's sense organ and the brains look, has the intellectualized characteristic is the integration of machinery and the machinery electrification distinguishes in the function essence.2. Integration of machinery development condition integration of machinery development may divide into 3 stages roughly.20th century 60's before for the first stage, this stage is called the initial stage .In this time, the people determination not on own initiative uses the electronic technology the preliminary achievement to consummate the mechanical product the performance .Specially in Second World War period, the war has stimulated the mechanical product and the electronic technology union, these mechanical and electrical union military technology, postwar transfers civilly, to postwar economical restoration positive function .Developed and the development at that time generally speaking also is at the spontaneous condition .Because at that time the electronic technology development not yet achieved certain level, mechanical technical and electronic technology union also not impossible widespread and thorough development, already developed the product was also unable to promote massively. The 20th century 70~80 ages for the second stage, may be called the vigorous development stage .This time, the computer technology, the control technology, the communication development, has laid the technology base for the integration of machinery development . Large-scale, ultra large scale integrated circuit and microcomputer swift and violent development, has provided the full material base for the integration of machinery development .This time characteristic is :①A mechatronics word first generally is accepted in Japan, probably obtains the quite widespread acknowledgment to 1980s last stages in the worldwide scale ;②The integration of machinery technology and the product obtained the enormous development ;③The various countries start to the integration of machinery technology and the product give the very big attention and the support. 1990s later periods, started the integration of machinery technology the new stage which makes great strides forward to the intellectualized direction, the integration of machinery enters the thorough development time .At the same time, optics, the communication and so on entered the integration of machinery, processes the technology also zhan to appear tiny in the integration of machinery the foot, appeared the light integration of machinery and the micro integration of machinery and so on the newbranch; On the other hand to the integration of machinery system modeling design, the analysis and the integrated method, the integration of machinery discipline system and the trend of development has all conducted the thorough research .At the same time, because the huge progress which domains and so on artificial intelligence technology, neural network technology and optical fiber technology obtain, opened the development vast world for the integration of machinery technology .These research, will urge the integration of machinery further to establish the integrity the foundation and forms the integrity gradually the scientific system. Our country is only then starts from the beginning of 1980s in this aspect to study with the application .The State Council had been established the integration of machinery leading group and lists as "863 plans" this technology .When formulated "95" the plan and in 2010 developed the summary had considered fully on international the influence which and possibly brought from this about the integration of machinery technology development trend .Many universities, colleges and institutes, the development facility and some large and middle scale enterprises have done the massive work to this technical development and the application, does not yield certain result, but and so on the advanced countries compared with Japan still has the suitable disparity.3. Integration of machinery trend of development integrations of machinery are the collection machinery, the electron, optics, the control, the computer, the information and so on the multi-disciplinary overlapping syntheses, its development and the progress rely on and promote the correlation technology development and the progress .Therefore, the integration of machinery main development direction is as follows:3.1 Intellectualized intellectualizations are 21st century integration of machinery technological development important development directions .The artificial intelligence obtains day by day in the integration of machinery constructor's research takes, the robot and the numerical control engine bed intellectualization is the important application .Here said "the intellectualization" is to the machine behavior description, is in the control theory foundation, the absorption artificial intelligence, theoperations research, the computer science, the fuzzy mathematics, the psychology, the physiology and the chaos dynamics and so on the new thought, the new method, simulate the human intelligence, enable it to have abilities and so on judgment inference, logical thinking, independent decision-making, obtains the higher control goal in order to .Indeed, enable the integration of machinery product to have with the human identical intelligence, is not impossible, also is nonessential .But, the high performance, the high speed microprocessor enable the integration of machinery product to have preliminary intelligent or human's partial intelligences, then is completely possible and essential.In the modern manufacture process, the information has become the control manufacture industry the determining factor, moreover is the most active actuation factor .Enhances the manufacture system information-handling capacity to become the modern manufacture science development a key point .As a result of the manufacture system information organization and structure multi-level, makes the information the gain, the integration and the fusion presents draws up the character, information measure multi-dimensional, as well as information organization's multi-level .In the manufacture information structural model, manufacture information uniform restraint, dissemination processing and magnanimous data aspects and so on manufacture knowledge library management, all also wait for further break through.Each kind of artificial intelligence tool and the computation intelligence method promoted the manufacture intelligence development in the manufacture widespread application .A kind based on the biological evolution algorithm computation intelligent agent, in includes thescheduling problem in the combination optimization solution area of technology, receives the more and more universal attention, hopefully completes the combination optimization question when the manufacture the solution speed and the solution precision aspect breaks through the question scale in pairs the restriction .The manufacture intelligence also displays in: The intelligent dispatch, the intelligent design, the intelligentprocessing, the robot study, the intelligent control, the intelligent craft plan, the intelligent diagnosis and so on are variousThese question key breakthrough, may form the product innovation the basic research system. Between 2 modern mechanical engineering front science different science overlapping fusion will have the new science accumulation, the economical development and society's progress has had the new request and the expectation to the science and technology, thus will form the front science .The front science also has solved and between the solution scientific question border area .The front science has the obvious time domain, the domain and the dynamic characteristic .The project front science distinguished in the general basic science important characteristic is it has covered the key science and technology question which the project actual appeared.Manufacture system is a complex large-scale system, for satisfies the manufacture system agility, the fast response and fast reorganization ability, must profit from the information science, the life sciences and the social sciences and so on the multi-disciplinary research results, the exploration manufacture system new architecture, the manufacture pattern and the manufacture system effective operational mechanism .Makes the system optimization the organizational structure and the good movement condition is makes the system modeling , the simulation and the optimized essential target .Not only the manufacture system new architecture to makes the enterprise the agility and may reorganize ability to the demand response ability to have the vital significance, moreover to made the enterprise first floor production equipment the flexibility and may dynamic reorganization ability set a higher request .The biological manufacture view more and more many is introduced the manufacture system, satisfies the manufacture system new request.The study organizes and circulates method and technique of complicated system from the biological phenomenon, is a valid exit which will solve many hard nut to cracks that manufacturing industry face from now on currently .Imitating to living what manufacturing point is mimicry living creature organ of from the organization, from matchmore, from growth with from evolution etc. function structure and circulate mode of a kind of manufacturing system and manufacturing process.The manufacturing drives in the mechanism under, continuously by one's own perfect raise on organizing structure and circulating mode and thus to adapt the process of[with] ability for the environment .For from descend but the last product proceed together a design and make a craft rules the auto of the distance born, produce system of dynamic state reorganization and product and manufacturing the system tend automatically excellent provided theories foundation and carry out a condition .Imitate to living a manufacturing to belong to manufacturing science and life science of\"the far good luck is miscellaneous to hand over\", it will produce to the manufacturing industry for 21 centuries huge of influence .翻译:机电一体化摘要机电一体化是现代科学技术发展的必然结果,本文简述了机电一体化技术的基本概要和发展背景。

毕业论文中英文资料外文翻译文献附录附录1:英文原文Selection of optimum tool geometry and cutting conditionsusing a surface roughness prediction model for end milling Abstract Influence of tool geometry on the quality of surface produced is well known and hence any attempt to assess the performance of end milling should include the tool geometry. In the present work, experimental studies have been conducted to see the effect of tool geometry (radial rake angle and nose radius) and cutting conditions (cutting speed and feed rate) on the machining performance during end milling of medium carbon steel. The first and second order mathematical models, in terms of machining parameters, were developed for surface roughness prediction using response surface methodology (RSM) on the basis of experimental results. The model selected for optimization has been validated with the Chi square test. The significance of these parameters on surface roughness has been established with analysis of variance. An attempt has also been made to optimize the surface roughness prediction model using genetic algorithms (GA). The GA program gives minimum values of surface roughness and their respective optimal conditions.1 IntroductionEnd milling is one of the most commonly used metal removal operations in industry because of its ability to remove material faster giving reasonably good surface quality. It is used in a variety of manufacturing industries including aerospace and automotive sectors, where quality is an important factor in the production of slots, pockets, precision moulds and dies. Greater attention is given to dimensional accuracy and surface roughness of products by the industry these days. Moreover, surface finish influences mechanical properties such as fatigue behaviour, wear, corrosion, lubrication and electrical conductivity. Thus, measuring and characterizing surface finish can be considered for predicting machining performance.Surface finish resulting from turning operations has traditionally received considerable research attention, where as that of machining processes using multipoint cutters, requires attention by researchers. As these processes involve large number of parameters, it would bedifficult to correlate surface finish with other parameters just by conducting experiments. Modelling helps to understand this kind of process better. Though some amount of work has been carried out to develop surface finish prediction models in the past, the effect of tool geometry has received little attention. However, the radial rake angle has a major affect on the power consumption apart from tangential and radial forces. It also influences chip curling and modifies chip flow direction. In addition to this, researchers [1] have also observed that the nose radius plays a significant role in affecting the surface finish. Therefore the development of a good model should involve the radial rake angle and nose radius along with other relevant factors.Establishment of efficient machining parameters has been a problem that has confronted manufacturing industries for nearly a century, and is still the subject of many studies. Obtaining optimum machining parameters is of great concern in manufacturing industries, where the economy of machining operation plays a key role in the competitive market. In material removal processes, an improper selection of cutting conditions cause surfaces with high roughness and dimensional errors, and it is even possible that dynamic phenomena due to auto excited vibrations may set in [2]. In view of the significant role that the milling operation plays in today’s manufacturing world, there is a need to optimize the machining parameters for this operation. So, an effort has been made in this paper to see the influence of tool geometry(radial rake angle and nose radius) and cutting conditions(cutting speed and feed rate) on the surface finish produced during end milling of medium carbon steel. The experimental results of this work will be used to relate cutting speed, feed rate, radial rake angle and nose radius with the machining response i.e. surface roughness by modelling. The mathematical models thus developed are further utilized to find the optimum process parameters using genetic algorithms.2 ReviewProcess modelling and optimization are two important issues in manufacturing. The manufacturing processes are characterized by a multiplicity of dynamically interacting process variables. Surface finish has been an important factor of machining in predicting performance of any machining operation. In order to develop and optimize a surface roughness model, it is essential to understand the current status of work in this area.Davis et al. [3] have investigated the cutting performance of five end mills having various helix angles. Cutting tests were performed on aluminium alloy L 65 for three milling processes (face, slot and side), in which cutting force, surface roughness and concavity of a machined plane surface were measured. The central composite design was used to decide on the number of experiments to be conducted. The cutting performance of the end mills was assessed usingvariance analysis. The affects of spindle speed, depth of cut and feed rate on the cutting force and surface roughness were studied. The investigation showed that end mills with left hand helix angles are generally less cost effective than those with right hand helix angles. There is no significant difference between up milling and down milling with regard tothe cutting force, although the difference between them regarding the surface roughness was large. Bayoumi et al.[4] have studied the affect of the tool rotation angle, feed rate and cutting speed on the mechanistic process parameters (pressure, friction parameter) for end milling operation with three commercially available workpiece materials, 11 L 17 free machining steel, 62- 35-3 free machining brass and 2024 aluminium using a single fluted HSS milling cutter. It has been found that pressure and friction act on the chip – tool interface decrease with the increase of feed rate and with the decrease of the flow angle, while the cutting speed has a negligible effect on some of the material dependent parameters. Process parameters are summarized into empirical equations as functions of feed rate and tool rotation angle for each work material. However, researchers have not taken into account the effects of cutting conditions and tool geometry simultaneously; besides these studies have not considered the optimization of the cutting process.As end milling is a process which involves a large number f parameters, combined influence of the significant parameters an only be obtained by modelling. Mansour and Abdallaet al. [5] have developed a surface roughness model for the end milling of EN32M (a semi-free cutting carbon case hardening steel with improved merchantability). The mathematical model has been developed in terms of cutting speed, feed rate and axial depth of cut. The affect of these parameters on the surface roughness has been carried out using response surface methodology (RSM). A first order equation covering the speed range of 30–35 m/min and a second order equation covering the speed range of 24–38 m/min were developed under dry machining conditions. Alauddin et al. [6] developed a surface roughness model using RSM for the end milling of 190 BHN steel. First and second order models were constructed along with contour graphs for the selection of the proper combination of cutting speed and feed to increase the metal removal rate without sacrificing surface quality. Hasmi et al. [7] also used the RSM model for assessing the influence of the workpiece material on the surface roughness of the machined surfaces. The model was developed for milling operation by conducting experiments on steel specimens. The expression shows, the relationship between the surface roughness and the various parameters; namely, the cutting speed, feed and depth of cut. The above models have not considered the affect of tool geometry on surface roughness.Since the turn of the century quite a large number of attempts have been made to find optimum values of machining parameters. Uses of many methods have been reported in the literature to solve optimization problems for machining parameters. Jain and Jain [8] have usedneural networks for modeling and optimizing the machining conditions. The results have been validated by comparing the optimized machining conditions obtained using genetic algorithms. Suresh et al. [9] have developed a surface roughness prediction model for turning mild steel using a response surface methodology to produce the factor affects of the individual process parameters. They have also optimized the turning process using the surface roughness prediction model as the objective function. Considering the above, an attempt has been made in this work to develop a surface roughness model with tool geometry and cutting conditions on the basis of experimental results and then optimize it for the selection of these parameters within the given constraints in the end milling operation.3 MethodologyIn this work, mathematical models have been developed using experimental results with the help of response surface methodolog y. The purpose of developing mathematical models relating the machining responses and their factors is to facilitate the optimization of the machining process. This mathematical model has been used as an objective function and the optimization was carried out with the help of genetic algorithms.3.1 Mathematical formulationResponse surface methodology(RSM) is a combination of mathematical and statistical techniques useful for modelling and analyzing the problems in which several independent variables influence a dependent variable or response. The mathematical models commonly used are represented by:where Y is the machining response, ϕ is the response function and S, f , α, r are milling variables and ∈is the error which is normally distributed about the observed response Y with zero mean.The relationship between surface roughness and other independent variables can be represented as follows,where C is a constant and a, b, c and d are exponents.To facilitate the determination of constants and exponents, this mathematical model will have to be linearized by performing a logarithmic transformation as follows:The constants and exponents C, a, b, c and d can be determined by the method of least squares. The first order linear model, developed from the above functional relationship using least squares method, can be represented as follows:where Y1 is the estimated response based on the first-order equation, Y is the measured surface roughness on a logarithmic scale, x0 = 1 (dummy variable), x1, x2, x3 and x4 are logarithmic transformations of cutting speed, feed rate, radial rake angle and nose radiusrespectively, ∈is the experimental error and b values are the estimates of corresponding parameters.The general second order polynomial response is as given below:where Y2 is the estimated response based on the second order equation. The parameters, i.e. b0, b1, b2, b3, b4, b12, b23, b14, etc. are to be estimated by the method of least squares. Validity of the selected model used for optimizing the process parameters has been tested with the help of statistical tests, such as F-test, chi square test, etc. [10].3.2 Optimization using genetic algorithmsMost of the researchers have used traditional optimization techniques for solving machining problems. The traditional methods of optimization and search do not fare well over a broad spectrum of problem domains. Traditional techniques are not efficient when the practical search space is too large. These algorithms are not robust. They are inclined to obtain a local optimal solution. Numerous constraints and number of passes make the machining optimization problem more complicated. So, it was decided to employ genetic algorithms as an optimization technique. GA come under the class of non-traditional search and optimization techniques. GA are different from traditional optimization techniques in the following ways:1.GA work with a coding of the parameter set, not the parameter themselves.2.GA search from a population of points and not a single point.3.GA use information of fitness function, not derivatives or other auxiliary knowledge.4.GA use probabilistic transition rules not deterministic rules.5.It is very likely that the expected GA solution will be the global solution.Genetic algorithms (GA) form a class of adaptive heuristics based on principles derived from the dynamics of natural population genetics. The searching process simulates the natural evaluation of biological creatures and turns out to be an intelligent exploitation of a random search. The mechanics of a GA is simple, involving copying of binary strings. Simplicity of operation and computational efficiency are the two main attractions of the genetic algorithmic approach. The computations are carried out in three stages to get a result in one generation or iteration. The three stages are reproduction, crossover and mutation.In order to use GA to solve any problem, the variable is typically encoded into a string (binary coding) or chromosome structure which represents a possible solution to the given problem. GA begin with a population of strings (individuals) created at random. The fitness of each individual string is evaluated with respect to the given objective function. Then this initial population is operated on by three main operators – reproduction cross over and mutation– to create, hopefully, a better population. Highly fit individuals or solutions are given theopportunity to reproduce by exchanging pieces of their genetic information, in the crossover procedure, with other highly fit individuals. This produces new “offspring” solutions, which share some characteristics taken from both the parents. Mutation is often applied after crossover by altering some genes (i.e. bits) in the offspring. The offspring can either replace the whole population (generational approach) or replace less fit individuals (steady state approach). This new population is further evaluated and tested for some termination criteria. The reproduction-cross over mutation- evaluation cycle is repeated until the termination criteria are met.4 Experimental detailsFor developing models on the basis of experimental data, careful planning of experimentation is essential. The factors considered for experimentation and analysis were cutting speed, feed rate, radial rake angle and nose radius.4.1 Experimental designThe design of experimentation has a major affect on the number of experiments needed. Therefore it is essential to have a well designed set of experiments. The range of values of each factor was set at three different levels, namely low, medium and high as shown in Table 1. Based on this, a total number of 81 experiments (full factorial design), each having a combination of different levels of factors, as shown in Table 2, were carried out.The variables were coded by taking into account the capacity and limiting cutting conditions of the milling machine. The coded values of variables, to be used in Eqs. 3 and 4, were obtained from the following transforming equations:where x1 is the coded value of cutting speed (S), x2 is the coded value of the feed rate ( f ), x3 is the coded value of radial rake angle(α) and x4 is the coded value of nose radius (r).4.2 ExperimentationA high precision ‘Rambaudi Rammatic 500’ CNC milling machine, with a vertical milling head, was used for experimentation. The control system is a CNC FIDIA-12 compact. The cutting tools, used for the experimentation, were solid coated carbide end mill cutters of different radial rake angles and nose radii (WIDIA: DIA20 X FL38 X OAL 102 MM). The tools are coated with TiAlN coating. The hardness, density and transverse rupture strength are 1570 HV 30, 14.5 gm/cm3 and 3800 N/mm2 respectively.AISI 1045 steel specimens of 100×75 mm and 20 mm thickness were used in the present study. All the specimens were annealed, by holding them at 850 ◦C for one hour and then cooling them in a furnace. The chemical analysis of specimens is presented in Table 3. Thehardness of the workpiece material is 170 BHN. All the experiments were carried out at a constant axial depth of cut of 20 mm and a radial depth of cut of 1 mm. The surface roughness (response) was measured with Talysurf-6 at a 0.8 mm cut-off value. An average of four measurements was used as a response value.5 Results and discussionThe influences of cutting speed, feed rate, radial rake angle and nose radius have been assessed by conducting experiments. The variation of machining response with respect to the variables was shown graphically in Fig. 1. It is seen from these figures that of the four dependent parameters, radial rake angle has definite influence on the roughness of the surface machined using an end mill cutter. It is felt that the prominent influence of radial rake angle on the surface generation could be due to the fact that any change in the radial rake angle changes the sharpness of the cutting edge on the periphery, i.e changes the contact length between the chip and workpiece surface. Also it is evident from the plots that as the radial rake angle changes from 4◦to 16◦, the surface roughness decreases and then increases. Therefore, it may be concluded here that the radial rake angle in the range of 4◦to 10◦would give a better surface finish. Figure 1 also shows that the surface roughness decreases first and then increases with the increase in the nose radius. This shows that there is a scope for finding the optimum value of the radial rake angle and nose radius for obtaining the best possible quality of the surface. It was also found that the surface roughness decreases with an increase in cutting speed and increases as feed rate increases. It could also be observed that the surface roughness was a minimum at the 250 m/min speed, 200 mm/min feed rate, 10◦radial rake angle and 0.8 mm nose radius. In order to understand the process better, the experimental results can be used to develop mathematical models using RSM. In this work, a commercially available mathematical software package (MATLAB) was used for the computation of the regression of constants and exponents.5.1 The roughness modelUsing experimental results, empirical equations have been obtained to estimate surface roughness with the significant parameters considered for the experimentation i.e. cutting speed, feed rate, radial rake angle and nose radius. The first order model obtained from the above functional relationship using the RSM method is as follows:The transformed equation of surface roughness prediction is as follows:Equation 10 is derived from Eq. 9 by substituting the coded values of x1, x2, x3 and x4 in termsof ln s, ln f , lnαand ln r. The analysis of the variance (ANOV A) and the F-ratio test have been performed to justify the accuracy of the fit for the mathematical model. Since the calculated values of the F-ratio are less than the standard values of the F-ratio for surface roughness as shown in Table 4, the model is adequate at 99% confidence level to represent the relationship between the machining response and the considered machining parameters of the end milling process.The multiple regression coefficient of the first order model was found to be 0.5839. This shows that the first order model can explain the variation in surface roughness to the extent of 58.39%. As the first order model has low predictability, the second order model has been developed to see whether it can represent better or not.The second order surface roughness model thus developed is as given below:where Y2 is the estimated response of the surface roughness on a logarithmic scale, x1, x2, x3 and x4 are the logarithmic transformation of speed, feed, radial rake angle and nose radius. The data of analysis of variance for the second order surface roughness model is shown in Table 5.Since F cal is greater than F0.01, there is a definite relationship between the response variable and independent variable at 99% confidence level. The multiple regression coefficient of the second order model was found to be 0.9596. On the basis of the multiple regression coefficient (R2), it can be concluded that the second order model was adequate to represent this process. Hence the second order model was considered as an objective function for optimization using genetic algorithms. This second order model was also validated using the chi square test. The calculated chi square value of the model was 0.1493 and them tabulated value at χ2 0.005 is 52.34, as shown in Table 6, which indicates that 99.5% of the variability in surface roughness was explained by this model.Using the second order model, the surface roughness of the components produced by end milling can be estimated with reasonable accuracy. This model would be optimized using genetic algorithms (GA).5.2 The optimization of end millingOptimization of machining parameters not only increases the utility for machining economics, but also the product quality toa great extent. In this context an effort has been made to estimate the optimum tool geometry and machining conditions to produce the best possible surface quality within the constraints.The constrained optimization problem is stated as follows: Minimize Ra using the model given here:where xil and xiu are the upper and lower bounds of process variables xi and x1, x2, x3, x4 are logarithmic transformation of cutting speed, feed, radial rake angle and nose radius.The GA code was developed using MATLAB. This approach makes a binary coding system to represent the variables cutting speed (S), feed rate ( f ), radial rake angle (α) and nose radius (r), i.e. each of these variables is represented by a ten bit binary equivalent, limiting the total string length to 40. It is known as a chromosome. The variables are represented as genes (substrings) in the chromosome. The randomly generated 20 such chromosomes (population size is 20), fulfilling the constraints on the variables, are taken in each generation. The first generation is called the initial population. Once the coding of the variables has been done, then the actual decoded values for the variables are estimated using the following formula: where xi is the actual decoded value of the cutting speed, feed rate, radial rake angle and nose radius, x(L) i is the lower limit and x(U) i is the upper limit and li is the substring length, which is equal to ten in this case.Using the present generation of 20 chromosomes, fitness values are calculated by the following transformation:where f(x) is the fitness function and Ra is the objective function.Out of these 20 fitness values, four are chosen using the roulette-wheel selection scheme. The chromosomes corresponding to these four fitness values are taken as parents. Then the crossover and mutation reproduction methods are applied to generate 20 new chromosomes for the next generation. This processof generating the new population from the old population is called one generation. Many such generations are run till the maximum number of generations is met or the average of four selected fitness values in each generation becomes steady. This ensures that the optimization of all the variables (cutting speed, feed rate, radial rake angle and nose radius) is carried out simultaneously. The final statistics are displayed at the end of all iterations. In order to optimize the present problem using GA, the following parameters have been selected to obtain the best possible solution with the least computational effort: Table 7 shows some of the minimum values of the surface roughness predicted by the GA program with respect to input machining ranges, and Table 8 shows the optimum machining conditions for the corresponding minimum values of the surface roughness shown in Table 7. The MRR given in Table 8 was calculated bywhere f is the table feed (mm/min), aa is the axial depth of cut (20 mm) and ar is the radial depth of cut (1 mm).It can be concluded from the optimization results of the GA program that it is possible toselect a combination of cutting speed, feed rate, radial rake angle and nose radius for achieving the best possible surface finish giving a reasonably good material removal rate. This GA program provides optimum machining conditions for the corresponding given minimum values of the surface roughness. The application of the genetic algorithmic approach to obtain optimal machining conditions will be quite useful at the computer aided process planning (CAPP) stage in the production of high quality goods with tight tolerances by a variety of machining operations, and in the adaptive control of automated machine tools. With the known boundaries of surface roughness and machining conditions, machining could be performed with a relatively high rate of success with the selected machining conditions.6 ConclusionsThe investigations of this study indicate that the parameters cutting speed, feed, radial rake angle and nose radius are the primary actors influencing the surface roughness of medium carbon steel uring end milling. The approach presented in this paper provides n impetus to develop analytical models, based on experimental results for obtaining a surface roughness model using the response surface methodology. By incorporating the cutter geometry in the model, the validity of the model has been enhanced. The optimization of this model using genetic algorithms has resulted in a fairly useful method of obtaining machining parameters in order to obtain the best possible surface quality.中文翻译选择最佳工具,几何形状和切削条件利用表面粗糙度预测模型端铣摘要:刀具几何形状对工件表面质量产生的影响是人所共知的,因此,任何成型面端铣设计应包括刀具的几何形状。
