Unit1Two methods of designating limit dimensions are considered as standard.One method is the maximum material method in which the large dimension is placed above the smaller dimension for male parts, and the reverse is true for female parts.This method is well suited for small lot quantities because it is likely that the machinist himself may check the dimension of the parts .In so doing he will be verifying initially the large dimension of the male parts and the smaller dimension of the female part.other method is the maximum number method and is preferred by production and quality control departments .In this method of designating a dimension , the large number is always placed above the smaller number ,regardless of whether the part is male or female.两种方法都被看作是指定极限尺寸标准。
一种方法是最大的资料法,大尺寸较小的尺寸摆在上面男性部件,事实正相反对女性的部分。

机械工程师的关键责任之一是设计与分析机械系统。这涉及使用计算机辅助设计（CAD）软件创建系统的详细三维模型，并在不同条件下模拟其性能。通过分析作用于系统组件的力、应力和振动，机械工程师可以优化设计，确保安全、可靠和高效。
Case Study: Designing an Automotive Suspension System
案例研究：汽车悬挂系统设计
例如，让我们考虑一下汽车悬挂系统的设计。悬挂系统负责在保持车辆稳定控制的同时提供平稳的行驶。机械工程师使用CAD软件设计悬挂系统的各个组件，例如弹簧、减振器和控制臂。
在完成初始设计后，工程师将使用有限元分析（FEA）软件对系统进行分析。这样可以模拟系统在不同的道路条件下（如坑洼或减速带）的行为。通过分析组件中的应力和位移，工程师可以确定潜在的设计问题，并进行必要的修改，以改善悬挂系统的性能和安全性。
For example, let's consider the design of an automotive suspension system. A suspension system is responsible for providing a smooth ride while maintaining the stability and control of the vehicle. A mechanical engineer would use CAD software to design the various components of the suspension system, such as the springs, dampers, and control arms.
After the initial design is complete, the engineer would then analyze the system using finite element analysis (FEA) software. This allows them to simulate the behavior of the system under different road conditions, such as potholes or speed bumps. By analyzing the stresses and displacements in the components, the engineer can identify potential design issues and make necessary modifications to improve the performance and safety of the suspension system.

5.1 IntroductionConventional machining is the group of machining operations that use single- or multi-point tools to remove material in the form of chips. Metal cutting involves removing metal through machining operations. Machining traditionally takes place on lathes, drill presses, and milling machines with the use of various cutting tools. Most machining has very low set-up cost compared with forming, molding, and casting processes. However, machining is much more expensive for high volumes. Machining is necessary where tight tolerances on dimensions and finishes are required.5.1 译文传统机械加工是一组利用单刃或者多刃刀具以切屑形式去除材料的加工方式。
金属切削意味着通过机械加工去除金属。
传统的机械加工都是利用不同的刀具在车床、钻床和铣床上进行的。
与成型加工、锻压和铸造工艺相比，大多数机械加工的生产准备成本都较低，然而如果是大批量生产，其成本要高得多。
当对零件的尺寸公差和光洁度要求较高时，机械加工是很有必要的。
5.2 Turning and LatheTurning is one of the most common of metal cutting operations. In turning, a workpiece is rotated about its axis as single-point cutting tools are fed into it, shearing away excess material and creating the desired cylindrical surface. Turning can occur on both external and internal surfaces to produce an axially-symmetrical contoured part. Parts ranging from pocket watch components to large diameter marine propeller shafts can be turned on a lathe.Apart from turning, several other operations can also be performed on lathe.axially ['æksiəli] adv.轴向地symmetrical [si'metrikəl] a. 对称的cylindrical [si'lindrikl] a.圆柱形的contoured ['kɔntuəd] a.显示轮廓的，与某种形体轮廓相吻合的译文:在金属切削加工操作中，车削是最常见的一种。

1. Metals and Their UseIt is known that metals are very important in our life. Metals have the greatest importance for industry. All machines and other engineering constructions have metal parts; some of them consist only of metal parts.There are two large groups of metals:1) Simple metal- more or less pure chemical elements2) Alloys - materials consisting of a simple metal combined with some other elements.About two thirds of all elements found in the earth are metals, but not all metals may be used in industry. Those metals which are used in industry are called engineering metals. The most important engineering metal is iron , which in the form of alloys with carbon and other elements, finds greater use than any other metal. Metals consisting of iron combined with some other elements are known as ferrous metals; all the other metals are called nonferrous metals. The most important nonferrous metal are copper , aluminum , lead , zinc , tin , but all these metals are used much less than ferrous metals, because the ferrous metals are much cheaper.Engineering metals are used in industry in the form of alloys because the properties of alloys are much better than the properties of pure metals. Only aluminum may be largely used in the form of simple metal. Metals have such a great importance because of their useful properties or their strength, hardness, and their plasticity .Different metals are produced in different ways, but almost all the metal are found in the forms of metal ore (iron ore, copper ore, etcet cetra.)The ore is a mineral consistence of a metal combined with some impurities . In order to produce a metal from some metal ore, we must separate these impurities from the metal that is done by metallurgy .2. Plastics and Other MaterialsPlastics have specific properties which may make them preferable to traditional materials for certain uses. In comparison with metals, for example, plastics have both advantages and disadvantages. Metals tend to be corroded by inorganic acids , such as sulphuric acid and hydrochloric acid. Plastics tend to be resistant to these acids, but can have dissolved or deformed by solvent , such as carbon tetrachloride , which have the same carbon base as the plastics. Color must be applied to the surface of metals, whereas it can be mixed in with plastics. Metals are more rigid than most plastics while plastics are very light, with a specific gravity normally between 0.9 and 1.8. Most plastics do not readily conduct heat or electricity . Plastics soften slowly and can easily be shaped when they are soft.塑料具有特殊的性能。

机械专业英语英译汉(3)Automatic Screw MachinesScrew machines are similar in construction to turret lathes, except that their heads are designed to hold and feed long bars of stock. Otherwise, there is little difference between them. Both are designed for multiple tooling, and both have adaptations for identical work. Originally, the turret lathe was designed as a chucking lathe for machining small castings, forgings, and irregularly shaped workpieces.The first screw machines were designed to feed bar stock and wire used in making small screw parts. Today, however, the turret lathe is frequently used with a collet attachment, and the automatic screw machine can be equipped with a chuck to hold castings.The single-spindle automatic screw machine, as its name implies, machines work on only one bar of stock at a time. A bar 16 to 20 feet long is fed through the headstock spindle and is held firmly by a collet. The machining operations are done by cutting tools mounted on the turret and on the cross slide. When the machine is in operation, the spindle and the stock are rotated at selected speeds for different operations. If required, rapid reversal of spindle direction is also possible.In the single-spindle automatic screw machine, a specific length of stock is automatically fed thr5ough the spindle to a machining area. At this point, the turret and cross slide move into position and automatically perform whatever operations are required. After the machined piece is cut off, stock is again fed into the machining area and the entire cycle is repeated.Multiple-spindle automatic screw machines have from four to eight spindles located around a spindle carrier. Long bars of stock, supported at the rear of the machine, pass through these hollow spindles and are gripped by collets. With the single spindle machine, the turret indexes around the spindle. When one tool on the turret is working, the others are not. With a multiple spindle machine, however, the spindle itself indexes. Thus the bars of stock are carried to the various end working and side working tools. Each tool operates in only one position, but all tools operate simultaneously. Therefore, four to eight workpieces can be machined at the same time. 《机械工程专业英语》电子工业出版社施平自动螺丝车床螺丝车床在结构上与转塔车床类似，不同之处是螺丝车床的主轴头部能被设计用来夹持和送进长棒料。

Text 1 Phases of Aircraft DesignConceptual DesignAircraft design can be broken into three major phases, Conceptual Design, Preliminary Design and Detail Design. Conceptual design is the primary focus of this book. It is in conceptual design that the basic questions of configuration arrangement, size and weight, and performance are answered.The first question is, “Can an affordable aircraft be built that meets the requirements?” If not, the customer may wish to relax the requirement.Conceptual design is a very fluid process. New ideas and problems emerge as a design is investigated in ever-increasing detail. Each time the latest design is analyzed and sized, it must be redrawn to reflect the new gross weight, fuel weight, wing size, engine size, and other changes. Early wing-tunnel tests often reveal problems requiring some changes to the configuration. The steps of conceptual design are described later in more detail.飞机设计可以分成三个主要的阶段：概念设计、初步设计和详细设计。

第三课Overview of Engineering Mechanics工程力学概述当我们观察我们周围就会发现世界充满“物品”：机器，设备，工具；我们已经设计，建造，并使用的物品；木头，金属，陶瓷和塑料制品。
根据我们使用的经验知道，有些物品比其它物品更好；他们使用寿命较长，费用较低，噪音更低，更好看，或者更方便我们使用。
然而，在理想的情况下，每一件产品都是设计人员工具其对某些“功能要求”的理解而设计出来的，也就是说，在设计过程中，应该回答这样的问题，即“它应该具有哪种确切的功能？”在工程领域，主要功能通常是承受由于重力，惯性力，压力等作用的一些类型的载荷。
从我们居住房屋的梁到飞机机翼，都必须有一个适当的材料，尺寸，在较合理的寿命基础上具有较合理的成本并能可靠地完成其功能的产品结构连接的组合。
在实践中，工程力学方法常被应用在两个完全不同领域：(1) 任何新装置的研发都需要对其结构，尺寸，材料，载荷，耐久性，安全和成本的反复考虑。
(2) 当一个装置（意外地）发生失效后，通常需要进行研究，找出失效的原因，并找出潜在的纠正措施。
最好的设计往往都是不断排除薄弱环节的演变过程。
对许多工程师来说，上述过程既可以令人非常的陶醉又可以使人非常的愉快，更何况（有时）对我们是有利的。
对于任何实际的问题，总是缺乏足够完整和有用的信息。
我们很少准确地知道实际荷载和工作状态，因此，所做的分析工作也很少是精确的。
虽然我们的数学可以准确，全面的分析一般只能近似，而且不同技术水平的人能得到不同的解。
在工程力学研究领域，大多数问题要想得到唯一解就要充分的理想化，但应该清楚，“现实世界”远不非理想化程度，因此为了得到问题的解决方案不得不进行一些理想化假设。
我们要考虑的技术领域通常被称为“静力学”和“材料力学”，“静力学”，指的是研究作用在固定装置上的作用力，“材料力学”指的是施加到结构的力（变形，载荷限制等）的影响。
但是，事实上很多设备都不是静态的，如果与动力学有关的额外负荷被考虑了的话，那么静力学的研究方法完全适用于动态的情况，只要动态力相对静态载荷较小，系统通常被认为是静态的。

• 1)忽略弹性变形。然而当必要时，弹性复原（例如，弯曲回弹情况）和加工中的弹性弯曲〈例如，成形加工精 度非常接近公差）定要考虑；
• 2)作为一种连续体来考〕单向拉伸或压縮试验与多向变形条件下的流动应力相互有关；
• 第7课模具的寿命和失效
• 正确的选择模具材枓和模具的制造技术，在很大程度上决定着成形模具的使用寿命。为着某些原 因，模具可能不得不更换，例如，由于磨损或塑性变形而使尺寸发生改变，表面损坏，光洁度降 低、润滑故障和裂纹即破裂。在热压模锻中，模具失效的主要模式是腐蚀作用、热疲劳、机械疲 劳和永久性即塑性变形。
• 虽然两大类材枓中，很可能金属类材科总是更加重要，伹非金属类材料的相对重要性 在迅速增强。由于新的非金属材料几乎是在不断地发明创造之中，这一趋势将确定无 疑地继续下去。许多情况下，金属和非金属之间的选择是由所需要性能的考虑原则来 确定的，两种材料的性能都能满足需要的时候，总成本就成了决定性因素。
• 一种材料对于另一种材枓常常借助于其物理性质来加以区别，例如颜色、密度、比热、 热膨胀系数，电、热传导性能，磁性和熔点。其中某些性能比如电、热传导性、密度， 对于某种的确定的用途来说，在选择材料时， 其重要性是摆在首位的。描述一种材 料在机械应用中的表现的那些性能，对于工程师在设计中选择材料来说，往往更为重 要。这些机械性能关系到该材料在工作中对于各种载荷怎样地起作用。
• 机械性能是材料对所施加的作用力的特性反应（响应）。这些性能主要归结到五大类： 强度、硬度、弹性、延展性和韧性。
• 1. 强度——是材料抵抗外力作用的能力。升降机的钢丝绳和建筑物的横梁都必须 具备这种性能。
• 2. 硬度——是材料抵抗穿透和磨损的能力。剪切工具（剪床）必须能抗磨损。轧 钢机上的金属轧辊必须能抗穿透。

第七单元Computer TechnologiesText 1The central and essential ingredient of CAD/CAM is the digital computer.CAD/CAM最重要的组成部分是数字计算机。
Its inherent speed and storage capacity have made it possible to achieve the advances is image processing, realtime process control, and a multitude of other important functions that are simply too complex and time-consuming to perform manually.数字计算机固有的速度及其存储能力使得CAD/CAM进行图像处理，实时控制以及其他许多重要功能若手工操作复杂又耗时能简单得进行成为可能。
To understand CAD/CAM, it is important to be familiar with the concepts and technoloty of the digital computer. 想要掌握CAD/CAM，熟悉数字计算机技术及理论是非常重要的。
The modern digital computer is an electronic machine that can perform mathematical and logical calculations and data processing functions in accordance with a predetermined program of instructions.现代数字计算机是一种可以根据预先设定的程序指令进行逻辑数据运算以及数据处理功能的电子仪器。
The computer itself is referred to as hardware, whereas the various programs are referred to as software.计算机本身称为硬件,而各种各样的程序都被称为软件。
There are three basic hardware components of a general-purpose digital computer:通用的数字计算机有如下三个基本组成设备：●Central processing unit (CPU) 中央处理单元(CPU)●Memory记忆单元●Input/output (I/O) section输入/输出单元The relationship of these three components is illustrate in Fig.1.1. The central processing unit is often considered to consist of two subsections: a control unit and an arithmetic-logic unit (ALU).三个设备的相关关系如图1.1所示。
中央处理单元往往被认为是由两个子单元组成：控制单元和数据逻辑单元（ALU）。
The control unit coordinates the operations of all the other components. It controls the input and output of information between the computer and the outside world through the I/O section.控制单元协调其他所有组件的操作，控制单元通过I/O部分控制计算机与外部环境信息的输入与输出。
Synchronizes the transference of the signals between the various sections of the computer, and command the other sections in the performance of their functions. The arithmetic-logic unit carries out the arithmetic and logic manipulations of data . It adds ,substracts, multiplies, divides, and compares numbers according to programmed instructions.指挥其他部分执行各自的功能。
数字逻辑单元控制数据的运算和逻辑操作。
根据程序指令进行加，减，乘，除以及数字的比较。
The memory of the computer is the storage unit .The data stored in this section are arranged in the form of words which can be conveniently transferred to the ALU or I/O section for processing.计算机的记忆单元是计算机的存储单元，数据以方便传输至ALU单元或者I/O部分并进行处理的语音形式存储在这一部分。
Finally, the input/output provides the means for the computer to communicate with the external world. This communication is accomplished through peripheral equipment such as readers,printers,and process interface devices.最后，输入/输出单元提供计算机与外部设备交互的方式。
这一交互是通过周边设备如读取器、打印机和过程控制接口设备实现的。
The computer may also connected to external storage units(e.g.tapes,didks,etc.) through the I/O section of the computer.计算机也可以通过计算机的I/O部分连接外部存储单元（如磁带，磁盘等）。
The software consists of the program and instructions stored in memory and in external storage units. It is the software that assigns the various functions which the user desires the system to accomplish to the computer. The useful of the computer's memory can be easily changed .and therefore different programs can be placed into memory, the digital computer can be used for a wide variety of applications.软件包括存储在内部和外部存储单元的程序和指令。
软件分配执行各种各样用户希望计算机去执行的功能。
有用的计算机内存可以很容易改变并且因此不同的程序可以放置进内存,数字计算机可以广泛应用于各种各样不同的场合。
Regardless of the application, the computer executes the program through its ability to manipulate data and numbers in their most elementary form. The data and numbers are represented in the computer by electrical signals which can take one of two alternative states. This form of representation is called the binary system. The more familiar decimal number system and a whole host of software languages can utilize the binary system to permit communication between computers and human beings.不管应用于哪种场合，计算机总是通过计算机本身最基本的操作数据和编号形式执行程序。
在计算机中数据及编号是通过在两种不同状态的电信号中选择一种状态表示的。
这种形式的表现被称为二进制系统。
更熟悉的十进制系统和许多软件语言可以利用二进制允许计算机和人之间的交互。
Central Processing Unit(CPU) 中央控制单元The central processing unit(CPU) regulates the operation of all system components and performs the arithmetic and logical operations on the data. To accomplish these functions,the CPU consists of two operating units:●Control unit●Arithmetic-logic unit(ALU)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:●控制单元●数字逻辑单元The control unit coordinates the various operations specified by the program instructions. These operations include receiving data which enter the computer and deciding how and when the data should be processed.The control unit directs the operation of the arithmetic-logic unit, It sends data to the ALU and tells the ALU what functions to perform on the data and where to store the results. The capability of the control unit to accomplish these operations is provided by a set of instructions called an executive program which is stored in memory.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，并决定何时和以何种方法来处理这些数据。
