机械工程英语第二版（叶邦彦陈统坚著）机械工程出版社课文翻译
Unit 1 材料的种类（1）材料的分类方法很多。
科学家常用的典型的方法是根据它们的状态分类：固体，液态或气态。
材料也分为有机（可再生）和无机材料（不可再生）。
（2）工业上，材料划分为工程材料或非工程材料。
工程材料用于制造和加工成零件的材料。
非工程材料是化学药品，燃料，润滑剂和其它用于制造又不用来加工成零件的材料。
（3）工程材料可进一步细分为：金属，陶瓷，复合材料，聚合材料，等。
Metals and Metal Alloys 金属和金属合金金属和金属合（4）金属有好的导电好导热性，很多金属有高的强度，高硬度和高的延展性。
象铁，钴，镍这些金属有磁性。
在非常低的温度下，一些金属和金属互化物变成超导体。
（5）合金和纯金属有什么区别？纯金属在元素周期表的特殊区域。
例如用于制造电线的铜和做锅和饮料罐的铝。
合金含有两种以上的金属元素。
改变金属元素的比例可以改变合金的性质。
例如，合金金属的不锈钢，是由铁，镍，和铬组成。
而黄金珠宝含有金镍合金。
（6）为什么要使用金属和合金？很多金属和合金有很高密度并用在要求质量与体积比高的的场合。
一些金属合金，象铝基合金，密度低，用在航空领域可以节省燃料。
很多合金有断裂韧度，可以承受冲击，且耐用。
金属有哪些重要属性？（7）【密度】质量除以体积叫做密度。
很多金属有相对高的密度,特别的，象聚合体。
高密度的材料常是原子量很大，象金或铅。
然而一些金属，像铝或镁密度低，就常常用在要求有金属特性而又要求低质量的场合。
（8）【断裂韧性】断裂韧度用来描述金属抗断裂的能力，特别的，当有裂纹时。
金属通常都有无关紧要的刻痕和凹坑，且有耐冲击性。
足球队员关注这一点当他确信面罩不会被击碎的时候。
（9）【塑形变形】塑性变形表述的是材料在断裂之前弯曲变形的能力。
作为工程师，我们通常设计材料使得能够在正常情况下不变形。
你不会想要一阵强烈的西风就把你的车刮得往东倾斜。
然而，有时，我们可以利用塑性变形。
汽车的承受极限就是在彻底破坏之前靠塑形变形来吸收能量。

Unit5 INDUSTRIAL ROBOT工业机器人INTRODUCTION介绍Industrial robots are relatively new electromechanical devices that are beginning to change the ap-pearance of modern industry. Industrial robots are not like the science fiction devices that possesshuman-iike abilities and provide companionship to space traveler、甲Research to enable robots to“see，"hear"，“touch"，and "listen" has been underway for two decades and is beginning to bearfruit. However，the current technology of industrial robots is such that most robots contain Onlyan arm rather than all the anatomy a human possesses. Current control only allows these devicesto move from point to point in space，performing relatively simple taskes. The Robotics Instituteof America defines a robot as“a reprogramrnab le multifunction manipulator designed to movematerial，parts, tools，or other specialized devices through variable programmed motions for theperformance of a variety of tasks. "' A NC machining center would qualify as a robot if one wereto interpret different types of machining as different functions- Most manufacturing engineers donot consider a NC machining center a robot，even though these machines hive a number of situ-ilarities. The power drive and controllers of both NC machines and robots can be quite similar.Robots, like NC machines can he powered by electrical motors，hydraulic systems，or pnetinlat tcsvsterns. Control for either device can lye either open-loop or closed-loop. In fact，many of thedevelopments used in robotics have evolved from the NC industry，and many of the manufactur-ers of robots also manufacture NC machines or NC controllers.工业机器人是相对来说较新的机电设备，它已经开始改变现代工业的面貌。

Unit 1 Metals金属绝对纯净的金属从来也没有被生产出来过。
即使绝对纯净的金属可以生产出来，工程师们对它们也并不会特别感兴趣，因为它们很柔软、脆弱。
实际应用中的金属往往都包含着一定数量的一种或多种外来金属或非金属元素，这些外来元素可能是有害的也可能是有益的或者它们对某种特定的属性没有影响。
如果是有害the crystals of the various grains are ran domly orie nted in space. The gra ins are everywhere in in timate con tact with oneanother and joined together on an atomic scale. The region at which they join is known as a grain boun dary.An absolutely pure metal (i.e. one composed of only one type of atom) has never been produced. Engin eers would not be particularly in terested in such a metal even if it were to be produced, because it would be soft and weak. The metals used commercially in evitably con ta in small amounts of one or more foreig neleme nts, either metallic or nonmetallic. These foreig neleme nts may be detrimental , they may be 它们的重量占所有生产出来的金属重量的98%在结构应用（也就是说，可以承受载荷的结构）中居于其次位置的是铝、铜、镍和钛。

U 1The use of metals has always a key factor in the development of the social systems of man. Of the roughly ['rʌfl ɪ] 100 basic elements of which all matter is composed, about half are classified as metals.金属的开发利用在人类社会系统的发展中扮演了了重要的角色，世界的物质大概由100种基本元素构成，其中一半是金属元素。
The distinction[dɪ'stɪŋkʃən] between a metal and a nonmetal is not always clear cut. The most basic definition centers around the type of bonding existing between the atoms of the element, and around the characteristics [,kærəkt ə'ristiks] of certain of the electrons[ɪ'lɛk,trɑn] associated with these atoms.金属与非金属的区分不是十分的清晰，最重要（基本）的在于元素原子之间的连接形式以及和原子相关联的电子的确定特性。

better surface finish. Grinding can be
performed on flat, cylindrical, or even
internal surfaces by employing specialized
machine tools, which are referred to as
显然，磨床根据结构和功能的不同有所区别， 使用何种形式的磨床主要取决于被磨削表 面的几何形状和物理性质。例如，圆柱面 在外圆磨床上磨削。

Type of Grinding Operations 磨削作业的类型
1. Surface grinding. As the name surface
grinding suggests, this operation involves
图8.1a和b同时简述了用于估计诸如加工时间 和金属去除率之类的磨削作业不同参数的 方程式。
h
7
During the surface-grinding operations, heavy workpieces are either held in fixtures or clamped on the machine table by strap clamps and the like, whereas smaller workpieces are usually held by magnetic chucks.
(2) 插入-切削方法：这种方法通过砂轮的横 向进给完成磨削而不采用轴向进给。正如 料想的那样，这种方法只在要磨削表面比 所用砂轮宽度短时才使用。
h
11
(3) The full-depth method, which is similar to the transverse method except that the grinding allowance is removed in a single pass. This method is usually recommended when grinding short rigid shafts.
grinding machines.
一般而言，磨削被认为是一种通常用于获得
高尺寸精度和较好表面光洁度的精加工作
业。磨削通过采用被称为磨床的特殊机床 能在平面、圆柱面甚至内表面上进行。
h

Obviously, grinding machines differ in construction as well as capabilities, and the type to be employed is determined mainly by the geometrical shape and nature of the surface to be ground, e.g., cylindrical surfaces are ground on cylindrical grinding machines.
在第一种情况(卧式主轴)，卧式磨床通常具有 安装工件的刨床式往复工作台。而立式主 轴磨床既可以像卧式主轴磨床那样具有刨 床式工作台也可以具有旋转工作台。

Also, the grinding action in this case is achieved by the end face of the grinding wheel (Fig.8.1b), contrary to the case of horizontal-spindle machines, where the workpieces ground by the periphery of the grinding wheel.
the wheel rotation is the source and cause
for the rotary cutting motion, as shown in
Fig.8.2. In fact, cylindrical grinding can be
carried out by employing any of the

Fig.8.1a and b also indicate the equations to be used for estimating the different parameters of the grinding operation, such as the machining time and the rate of metal removal.
grinding of flat or plane surfaces. Fig.8.1

1. 表面磨削：就像其名称暗示的那样，表面 磨削和平面磨削直接有关。图8.1表示了
无心磨削：无心磨削用于加工圆柱形工 件，工件由托板支撑，在两轮即砂轮和调 节或进给轮之间通过去。
h
16
The grinding wheel does the actual grinding, while the regulating wheel is responsible for rotating the workpiece as well as generating the longitudinal feed. This is possible because of the frictional characteristics of that wheel, which is usually made of rubber-bonded abrasive.
内表面磨削：内表面磨削用于相对较短 的孔，如图8.3所示。工件安装在卡盘或特 殊夹具上。作业时砂轮和工件都回转并且 采用纵向进给。
h
13
Any desired depth of cut can be obtained by the cross feed of the grinding wheel. A variation from this type is planetary internal grinding, which is recommended for heavy workpieces that cannot be held in chucks.
在平面磨削时，重的工件用夹具固定或用压 板等夹紧在磨床工作台上，而小的工件则 通常是用电磁卡盘固定的。

2. Cylindrical grinding. In cylindrical
grinding, the workpiece is held between
centers during the 除金属的制 造工艺。磨轮用非常大量的微型切削刃模 仿铣刀进行切削。

Generally, grinding is considered to be a
finishing process that is usually used for
obtaining high-dimensional accuracy and
(1) 横向方法：这种方法中砂轮与工件均旋转 且采用线性纵向进给以保证能磨削整个长 度。切削深度通过改变砂轮对工件的横向 进给来进行调整。
h
10
(2) The plunge-cut method, in which grinding is achieved through the cross feed of the grinding wheel and no axial feed is applied. As you can see, this method can be applied only when the surface to be ground is shorter than the width of the grinding wheel used.
Grinding is a manufacturing process that involves the removal of metal by employing a rotating abrasive wheel. The latter simulates a milling cutter with an extremely large number of miniature cutting edges.
在这种情况下，砂轮不但绕自身轴线回转， 同时还绕被磨削孔的中心线旋转。
h

Centerless grinding. Centerless grinding involves passing a cylindrical workpiece, which is supported by a rest blade, between two wheels, i.e., the grinding wheel and the regulating or feed wheel.
通过砂轮的横向进给能得到任意所需的切削 深度。这种方法的一个变体是行星式内表 面磨削，当工件较重不能用卡盘固定时推 荐使用。

In that case, the grinding wheel not only spins around its own axis but also rotates around the centerline of the hole that is being ground.
