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。

Unit 1 Passage A
Lathe Accessories
Brass Round Stock (铜质圆料) Brass is a nice material to work with, though somewhat expensive compared with aluminum or steel. It can add a nice touch of contrasting color to a project that will be displayed. The alloy most often used for home shop work is 360.
Poor quality drills are easy to find, but they are truly a waste of money. That‘s not to say that you need to buy top quality industrial drills. It’s not always easy to tell a good drill bit from a poor one just by looking and, of course, its even harder if all you have is a picture on a web site or in a catalog. Generally, though, the lowest priced drill sets are the ones to stay away from.

Rectilinear Motion. The feed of a tool on a lathe, the cutting of steel on a power saw, or the shaping of materials are all situations in which rectilinear or straight line motion produces work. In each of these situations a part or mechanism is used to change rotary motion to straight line motion. The screw of a micrometer and the threads in a nut are still other applications where the direction of motion is changed from rotary to rectilinear.[5] 5. the screw of a micrometer 意为“千分尺中的螺杆”全句可译为：千分尺中的螺杆和螺母中的螺纹是把运动方向从转动变为直线的另外一些应用实例。

第二版机械工程英语第二部分

Unit 11中央控制单元（CPU）的功能是控制所有系统部件的运行和对数据进行数字的或是逻辑的操作。

为了完成上述功能，CPU由以下两个单元组成2．控制单元．数字逻辑单元3控制单元通过程序指令来协调大量的特种操作，这些操作包括接受输入计算机的数据，并决定和是以何种方法来处理这些数据。

控制单元能指挥数字逻辑单元的操作，他把数据发送给ALU来告诉ALU根据这些数据该运行什么功能，并且在哪里把结果存储下来。

控制单元完成上述操作的能力基于其安装了一个具有储存与记忆功能的总控程序机构。

4数字逻辑单元运行诸如加减比较之类的操作。

这些操作是根据数据以二进制的形式表现出来的。

在指示了确定的条件下，逻辑部也可以用来改变命令执行的次序。

此外，逻辑部分还具有编辑或清除数据等功能。

5控制单元和数字逻辑单元都是得用寄存器来完成他们的功能的，计算机寄存器是一个可以接收短暂存储，转移数据的小记忆装置。

根据计算机能力的不同，寄存器能建立出相应的字节数的字长。

每个词的字节数从4到64不等！Unit 2生产设备的数字控制（1）数控是程序控制的自动化，在数字控制系统中，设备通过数字，字母和符号来编码，以一种合适的格式为每一个特定的零件或工件定义一个程序指令集。

当工件变化时，程序也变化，改变程序的能力也就是适合中小批量生产。

写一个新程序比改变大量生产设备要容易的多。

（2）基本结构：数控系统由下面三部分组成：1.控制程序；2.机器控制单元；3.加工设备。

三部分的基本关系，由图2.1 所示。

程序输入到控制单元由送入的程序来引导加工设备控制。

（3）指导程序是一步步详细的指导加工设备的指令。

通常指令把主轴上刀具相对于安装工具的工作台定位。

更多先进的说明包括主轴的转速，加工工具的选择及其功能。

程序刻在合适的介质中，提交到机器控制单元中，在过去几十年中，最常用的介质是一英寸宽的打孔纸带。

由于打孔纸带的广泛使用，NC 有时也叫纸带控制，然而这是现代数控使用的误称。

The individual reliability of machine elements becomes the basis for estimating the overall life expectancy of a complete machine. Many machine elements are thoroughly standardized. Testing and practical experience have established the most suitable dimensions for common structural and mechanical parts. Through standardization, uniformity of practice and resulting economics are obtained. Not all machine parts in use are standardized, however. In the automotive industry only fasteners, bearings, bushings, chains, and belts are standardized. Crankshafts and connecting rods are not standardized.

To hold work-pieces of irregular shapes, we often use a four-jaw chuck instead of a three-jaw chuck. Its accuracy is not affected by wear, because each jaw can be adjusted independently. The jaws do not move simultaneously.
3．This type of chuck is accurate when new．三爪卡盘在新的时候很精密。
句中“when”后省略了“it is”，即“…when it is new”。
4．It loses its accuracy as the jaws become worn．当卡爪磨损时，卡盘便会失去其精度。
In lathe work, work-pieces are held either between centers or in a chuck. Sometimes the work-pieces are held in a chuck at one end and supported by a center at the other.
Unit 2
The three-jaw universal chuck is used to hold cylindrical work. The chucking is done quickly, as the three jaws move in and out together and automatically center the work. This type of chuck is accurate when new. It loses its accuracy as the jaws become worn.

机械设计制造及其自动化专业英语第二版翻译(马玉录)

Unit 1 Metals金属The use of metals has always been a key factor in the development of the social systems of man. Of the roughly 100 basic elements of which all matter is composed, about half are classified as metals. The distinction 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 of certain of the electrons associated with these atoms. In a more practical way, however, a metal can be defined as an element which has a particular package of properties.Metals are crystalline when in the solid state and, with few exceptions (e.g. mercury), are solid at ambient temperatures. They are good conductors of heat and electricity and are opaque to light. They usually have a comparatively high density. Many metals are ductile-that is, their shape can be changed permanently by the application of a force without breaking. The forces required to cause this deformation and those required to break or fracture a metal are comparatively high, although, the fracture forces is not nearly as high as would be expected from simple consideration of the forces required to tear apart the atoms of the metal.One of the more significant of these characteristics from our point of view is that of在人类社会的发展中，金属的应用起着关键性的作用。
