The flexible manufacturing system The flexible manufacturing system(FMS) train points to have the high manufacturing system of the automation degree.The FMS speak about usually means in the lot size, batch size machining of metals currently with the forerunner's automation and Gao level of flexible is the manufacturing system of target.Along with society to product diversification, the low manufacturing cost and short manufacturing period's etc.'s need be gradually urgent, the FMS deveolps very and quickly, and because of micro-electronics technique, calculator technique, correspondence technique, machinery and the development of controlgear, also urge flexible manufacturing technique day attain mature, in 80's after, the manufacturing industry automation gets into for a brand-new ages, namely according to calculator of integrated manufacturing(CIMS) ages, the FMS has become the national machinery manufacturing of each industrialization to automate of develop and deveolp point.
A, scale
Press the scale all of the FMSs can be is divided into as follows 4 types:
1.Flexible Manufacturing Cellular(FMC)
The FMC publish and use to invite ratio FMS night in the manufacturing for 6~8 years, it is processed a centre, industrial robot by 1~2 and counts to control engine bed and material carrying to save to store equipments composing and have an adaptation to process have another species product of vivid.The FMC can be regarded as a FMS with minimum scale, is a FMS to cheap turn and small scaled turn direction development and a kind of outcome, its characteristics is to carry out single machine flexible turn and automate, have already get into up to the present universal application step.
2.Flexible Manufacturing System(FMS)
Usually include 4 or more full-automatic numbers to control engine bed(process centre and truning centre etc.), from concentrate the handling system of control system and material to connect, can under the sistuation that not shut down realization have another species, in process of small lot size, batch size and manage.
3.Flexible Manufacturing Line(FML)
It is be placed in the quantisty not- flexible and automatic line of single or
little species large quantity with medium small lot size, batch size have another of species FMS of manufacturing line.It processes an equipments and can be an in general use earth, ground to process a centre, CNC engine bed;May also adopt definite purpose engine bed or NC definite purpose engine bed, have low request at the FMS to the system flexible earth, ground of the material handling, but the rate of manufacturing be higher.It with the long-lost type produce medium flexible manufacturing system with connect the control system(DCS) of the dispersion type within manufacturing line is representative, its characteristics is to carry out manufacturing line flexible turn and automate, its technique already the day attain mature, have already got into application to turn step up to the present.
4.Flexible Manufacturing Factory(FMF)
The FMF connects several FMSs, go together with to automate stereoscopic storehouse, use the progress contact of the calculator system, adoption from order, design, process, assemble, examine, deliver to hair goods of complete FMS.It included CAD/CAM, and make calculator integrated to make system(CIMS) devotion physically, realization manufacturing the system be flexible to turn and automate and then carry out whole plant the manufacturing control, product of the scope to process and the material store completely turn of the luck progress.The FMF is the tallest level that the automation produce and the reflection is most born the top of the boundary the forerunner's automation application a technique.It is manufacturing, product development and management the automation of management connect into one whole, with information stream control substance stream of intelligence manufacturing system(IMS) is representative, its characteristics is to carry out works flexible turn and automate.
Two, key technique
https://www.360docs.net/doc/1d1576520.html,puter Aided Design, CAD
The CAD technique development will lead into the expert system in the future, make it have intelligence to turn, can treat various complicated question.At present design a latest of the technique breakthrough is that the light is quick stereoscopic forming technique, that the new technique be directly to make use of CAD data and pass a computer control of laser scanning system, be divided into some lamellas:3D
numerical pattern a two-dimensional flake form sketch, and press the two-dimensional flake form sketch to carry on an optics scanning to the quick resin liquid surface of the light in the bath, is scan of the liquid surface then becomes curing plastics, thus circularly operate, pursue lamella to scan to take shape, and of oneself glue the each flake form curing plastics that the delamination take shape to match together and only need certain data, then can make a prototype of precision in few hours.It contributes to quickly developping new product and developping the speed of new structure.
2.Fuzzy control technique
The actual application of misty mathematics is a fuzzy control machine.The high performance fuzzy control apparatus which develops recently has from the study function, can in the process of control in continuously obtain a new information and of oneself make an adjustment to the control quantisty, make system function greatly in order to improve, among them particularly with according to artificial neural net, artificial neural network, ANN of self-educated method cause people tremendous concern more.
3.Artificial intelligence, expert system and intelligence transducer technique
Up to the present, the artificial intelligence adopt mostly points according to the expert system of rule in the FMS.The expert system makes use of expert knowledge and reasons logically rule progress a reasoning and solve each kind of question.(like explanation, predict, diagnose, check to seek a fault, failure, design, plan, keep watch on, repair, command and control etc.)Because expert system can simplely the theory of various fact and experience certificate super - with pass the knowledge of experience acquisition to combine together, as a result the expert system intensified for the FMS various aspect operate gentle.Prospect a future, with knowledge intensively is characteristic, with the knowledge treat for the artificial intelligence(include expert system) technique of way necessarily will have in the FMS(particularly intelligence type) decisive action.The artificial intelligence is in the future FMS lieutenant general exertive gradually important https://www.360docs.net/doc/1d1576520.html,ed for various technique in the FMS currently, anticipate to there is the artificial intelligence of the is still of development prospect most .Anticipate till the beginning of 21 centuries, the artificial intelligence is in the FMS of applied scale will compare currently greatly
400%.The intelligence manufacturing technique(IMT) aim is in the process of integrating the artificial intelligence into the manufacturing each link, ask for help of intelligence of imitate the expert movable, replace or extend a manufacturing environment parts of mental works of the middleman.In the process of make, the system can automatically monitor it to circulate condition, while be subjected to the external world or inner excitation energy the automatic regulation its parameter with attain the best operating state, have self-organization ability.The past IMT is called make of the coming 21 centurieses technique.To the future intelligence turn 1 that the FMS has important meaning is an intelligence transducer in the realm of rapid development now technique.The item's technique accompanies with the technique of calculator application and artificial intelligence but creation and it makes the transducer have inside"decision" function.
4.Artificial neural net, artificial neural network, ANN technique
The artificial neural net, artificial neural network, ANN(ANN) is a kind of method that the neural net, neural network which imitates intelligence living creature proceeds together to treat to the information progress.The past artificial neural net, artificial neural network, ANN is also a kind of artificial intelligence tool.At the automatic control realm, the neural net, neural network soon will be be juxtaposed in expert system and fuzzy control system and become a modern from pay to turn a composition division in the system.
Three, deveolp trend
The 1. FMCs will become the popular technique which deveolps and applieds This is because the FMC investment is much less than the FMS but the economic performance connect near, be applicable to the financial power limited medium small scaled business enterprise more.Numerous foreign plant house lists as FMC to deveolp currently of heavy.
2.Deveolp the efficiency higher FML
Have another species large quantity the manufacturing business enterprise of the quantisty such as workses such as autocar and tractor etc. to FML of the need caused biggest pay attention to of the FMS manufactery.Adopt the price cheap definite purpose number controls engine bed to act for a process of general purpose a
centre and will be a FML development trend.
3.The dynasty multi-function direction deveolp
From the simplicity process the type FMS develops further to weld, assemble, inspection and Ban material process is to manufacturing work prefaces, such as Zhu and Duan...etc. and have of various function FMSs. The FMS is a realization future novel concept mode and new development trend of the works, decide to make raise of the strategic meaning of the have of prospect of the business enterprise future development Cuo.The FMS which reflects the works whole level currently is number generation FMS, in 90's this kind condition still will keep on next go to, Japan comes into force from 1991 of"intelligence manufacturing system"(IMS) be international to develop item and belong to the next generation FMS;But real perfect next generation FMS's anticipate would carry out to 21 centuries.Then, the intelligence turns machinery and the person's and will blend mutually and gentlely moderates completely from accept order goods to produce, sale this business enterprise produce the full activity of management.
Since the mid 80's, the FMS acquisition fast fierce development, almost became manufacturing automation of hot spot.On the other hand is because the single-item technique,such as NC, processes the development of centre, industrial robot, CAD/CAM, resources management and high technique etc. and provided to can be provided to integrate a technique foundation of whole system;On the other hand, the world market took place a graveness change, from past tradition, opposite stabilization of market, the development much changes into the dynamic state of the market , for begging existence and begging a development from the market, raise a business enterprise to the market demanding strain ability and people start investigate new manufacturing method and business model.In recent years, FMS conduct and actions a kind of science"philosophy" and works which modernizes industrial manufacturing automate of advanced mode already for the country the top of the border generally accepted, can think so:The FMS is automate a technique, information technology and makes technical foundation, former business enterprise in mutually independent engineering design, produce manufacturing and conduct a management etc. process, constitute a complete but organic system which overlays the whole

附：外文翻译 外文原文： Fundamentals of Mechanical Design Mechanical design means the design of things and systems of a mechanical nature—machines, products, structures, devices, and instruments. For the most part mechanical design utilizes mathematics, the materials sciences, and the engineering-mechanics sciences. The total design process is of interest to us. How does it begin? Does the engineer simply sit down at his desk with a blank sheet of paper? And, as he jots down some ideas, what happens next? What factors influence or control the decisions which have to be made? Finally, then, how does this design process end? Sometimes, but not always, design begins when an engineer recognizes a need and decides to do something about it. Recognition of the need and phrasing it in so many words often constitute a highly creative act because the need may be only a vague discontent, a feeling of uneasiness, of a sensing that something is not right. The need is usually not evident at all. For example, the need to do something about a food-packaging machine may be indicated by the noise level, by the variations in package weight, and by slight but perceptible variations in the quality of the packaging or wrap. There is a distinct difference between the statement of the need and the identification of the problem. Which follows this statement? The problem is more specific. If the need is for cleaner air, the problem might be that of reducing the dust discharge from power-plant stacks, or reducing the quantity of irritants from automotive exhausts. Definition of the problem must include all the specifications for the thing that is to be designed. The specifications are the input and output quantities, the characteristics of the space the thing must occupy and all the limitations on t hese quantities. We can regard the thing to be designed as something in a black box. In this case we must specify the inputs and outputs of the box together with their characteristics and limitations. The specifications define the cost, the number to be manufactured, the expected life, the range, the operating temperature, and the reliability. There are many implied specifications which result either from the designer's particular environment or from the nature of the problem itself. The manufacturing processes which are available, together with the facilities of a certain plant, constitute restrictions on a designer's freedom, and hence are a part of the implied specifications. A small plant, for instance, may not own cold-working machinery. Knowing this, the designer selects other metal-processing methods which can be performed in the plant. The labor skills available and the competitive situation also constitute implied specifications. After the problem has been defined and a set of written and implied specifications has been obtained, the next step in design is the synthesis of an optimum solution. Now synthesis cannot take place without both analysis and optimization because the system under design must be analyzed to determine whether the performance complies with the specifications. The design is an iterative process in which we proceed through several steps, evaluate the results, and then return to an earlier phase of the procedure. Thus we may synthesize several components of a system, analyze and optimize them, and return to synthesis to see what effect this has on the remaining parts of the system. Both analysis and optimization require that we construct or devise abstract models of the system which will admit some form of mathematical analysis. We call these models

Manufacturing Engineering and Technology—Machining Serope kalpakjian；Steven R.Schmid 机械工业出版社2004年3月第1版 20.9 MACHINABILITY The machinability of a material usually defined in terms of four factors: 1、Surface finish and integrity of the machined part; 2、Tool life obtained; 3、Force and power requirements; 4、Chip control. Thus, good machinability good surface finish and integrity, long tool life, and low force And power requirements. As for chip control, long and thin (stringy) cured chips, if not broken up, can severely interfere with the cutting operation by becoming entangled in the cutting zone. Because of the complex nature of cutting operations, it is difficult to establish relationships that quantitatively define the machinability of a material. In manufacturing plants, tool life and surface roughness are generally considered to be the most important factors in machinability. Although not used much any more, approximate machinability ratings are available in the example below. 20.9.1 Machinability Of Steels Because steels are among the most important engineering materials (as noted in Chapter 5), their machinability has been studied extensively. The machinability of steels has been mainly improved by adding lead and sulfur to obtain so-called free-machining steels. Resulfurized and Rephosphorized steels. Sulfur in steels forms manganese sulfide inclusions (second-phase particles), which act as stress raisers in the primary shear zone. As a result, the chips produced break up easily and are small; this improves machinability. The size, shape, distribution, and concentration of these inclusions significantly influence machinability. Elements such as tellurium and selenium, which are both chemically similar to sulfur, act as inclusion modifiers in

Int J Interact Des Manuf(2011)5:103–117 DOI10.1007/s12008-011-0119-7 ORIGINAL PAPER Benchmarking of virtual reality performance in mechanics education Maura Mengoni·Michele Germani· Margherita Peruzzini Received:27April2011/Accepted:29April2011/Published online:27May2011 ?Springer-Verlag2011 Abstract The paper explores the potentialities of virtual reality(VR)to improve the learning process of mechanical product design.It is focused on the definition of a proper experimental VR-based set-up whose performance matches mechanical design learning purposes,such as assemblability and tolerances prescription.The method consists of two main activities:VR technologies benchmarking based on sensory feedback and evaluation of how VR tools impact on learning curves.In order to quantify the performance of the technol-ogy,an experimental protocol is de?ned and an testing plan is set.Evaluation parameters are divided into performance and usability metrics to distinguish between the cognitive and technical aspects of the learning process.The experi-mental VR-based set up is tested on students in mechanical engineering through the application of the protocol. Keywords Mechanical product design·Virtual reality·Experimental protocol·Learning curve· Mechanics education 1Introduction Modern society is dominated by continuous scienti?c and technical developments.Specialization has become one of the most important enablers for industrial improvement.As a result,nowadays education is more and more job-oriented and technical education is assuming greater importance.In this context both university and industry are collaborating to create high professional competencies.The?rst disseminates M.Mengoni(B)·M.Germani·M.Peruzzini Department of Mechanical Engineering, Polytechnic University of Marche, Via Brecce Bianche,60131Ancona,Italy e-mail:m.mengoni@univpm.it knowledge and innovative methods while the second pro-vides a practical background for general principles training. The main problem deals with the effort and time required to improve technical learning,while market competitiveness forces companies to demand young and high-quali?ed engi-neers in short time.Therefore,the entire educational process needs to be fast and ef?cient.Novel information technolo-gies(IT)and emerging virtual reality(VR)systems provide a possible answer to the above-mentioned questions.Some of the most important issues,in mechanical design?eld,are the investigation of such technologies potentialities and the evaluation of achievable bene?ts in terms of product design learning effectiveness and quality.While IT has been deeply explored in distance education,i.e.e-learning,VR still rep-resents a novelty. VR refers to an immersive environment that allows pow-erful visualization and direct manipulation of virtual objects. It is widely used for several engineering applications as it provides novel human computer interfaces to interact with digital mock-ups.The close connection between industry and education represents the starting point of this research. Instead of traditional teaching methods,virtual technolo-gies can simultaneously stimulate the senses of vision by providing stereoscopic imaging views and complex spatial effects,of touch,hearing and motion by respectively adopt-ing haptic,sound and motion devices.These can improve the learning process in respect with traditional teaching meth-ods and tools.The observation of students interpreting two-dimensional drawings highlighted several dif?culties:the impact evaluation of geometric and dimensional tolerances chains,the detection of functional and assembly errors,the recognition of right design solutions and the choice of the proper manufacturing operations.These limitations force tutors to seek for innovative technologies able to improve students’perception.
