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.

弗朗姬：你在哪里工作？安德鲁：我在镇上新开的体育中心做兼职接待员。
弗朗姬：真棒！你都是什么时间工作？安德鲁：周二和周四晚上，还有周六。

安德鲁：是的，这份工作很适合我。
弗朗姬：工作怎么样？你喜欢吗？安德鲁：嗯，我喜欢。
工作环境很好，我的同事也很友善。
弗朗姬：有什么福利吗？安德鲁：我可以免费使用健身房和游泳池。
你呢？在做兼职吗？弗朗姬：实际上，下周我会有一个兼职销售助理的面试。
安德鲁：祝你好运！希望一切都能顺利。
参考译文成功还是失败？女主持：欢迎各位！今晚，我们将关注三位求职者的求职过程。
他们会成功还是失败呢？斯马特先生，我们的职业咨询顾问，将会在这里对求职者的表现作出评价。
首先让我们来看一下如何回答高难度的求职面试问题。
问题1：你最大的缺点是什么？求职者A：我不太有条理。
有几次我把重要的文件弄丢了好几次。
斯马特先生：哦，上帝啊！这位求职者很诚实，但这不是你应该在面试中承认的缺点。
试着想想对工作没有负面影响的缺点。
问题2：你为什么想要这份工作？求职者B：嗯，工资很高，而且您能提供公司用车，这点也很棒。
斯马特先生：另一个诚实的回答。
但是这位求职者并没有说她能给公司带来什么——只是提到了获得、获得、获得! 那她能带给工作环境什么呢？10问题3：你认为五年后你会变成什么样子？求职者C：我希望在工作了五年之后能够承担更多的责任。
斯马特先生：这个回答很好。
求职者很有野心，但是她没有说她要当老板（即使她真是这么想的！）面试前要考虑现实的目标，以显示出你对未来有一定的规划。
女主持人：太有趣了！那么，通过看这些求职者的回答，我们可以发现面试前认真准备是很重要的。
在面试前想好自己要说什么，让自己看起来真实又真诚，进而给面试官留下最佳印象。

Section II Text
Now people often talk about “feedback” as being an essential factor of the new in dustrial techniques, upon which is based an automatic self-regulating system and by virtue of which any deviation in the system from desired conditions can be det ected, measured , reported and corrected. When “feedback” is applied to the proc ess by which a large digital computer runs at the immense speed through a long s eries of sums, constantly rejecting the answers until it finds one to fit a complex set of facts that have been put to it, it is perhaps different in degree from what we have previously been accustomed to machines. But “feedback”, as such, is a famil iar mechanical conception. The old-fashioned steam engine was fitted with a cent rifugal governor, two balls on levers spinning round and round an upright shaft. I f the steam pressure rose and the engine started to go too fast, the increased spee d of the spinning governor caused it to rise up the vertical rod and shut down a va lve. This cut off some of the steam and thus the engine brought itself back to its p roper speed. The mechanization, which was introduced with the Industrial Revolution, beca use it was limited to individual processes, required the employment of human lab or to control each machine as well as to load and unload materials and transfer th em from one place to another. Only in a few instances were processes automatica lly linked together and was production organized as a continuous flow. End Topic Above 汉 Next

徐存善主编
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.

Unit 2 Some Rules for Mechanical Design 机电专业英语 图文课件
Text & Translation
The following tips may be helpful in stimulating creative ideas of the designers.
（1）Apply ingenuity to utilize desired physical properties and to limit undesired ones. ［3］The performance requirements of a machine are met by utilizing laws of nature or properties of matter (e.g.， flexibility，strength，gravity，inertia，buoyancy，centrifugal force， principles of the lever and inclined plane，friction，viscosity，fluid pressure，and thermal expansion)，also the many electrical，optical， thermal，and chemical phenomena. However，what may be useful in one application may be detrimental in the next. For example，flexibility is desirable in valve springs but not in the valve camshaft；friction is desirable at the clutch face but not in the clutch bearing. Ingenuity in design should be applied to utilize and control the physical properties that are desirable and to minimize those that are not desirable.

What can CAM be used for?3. What are the functions of computers in CAM?customer markets are different. Thesefactors give rise to differences in CAD system requirements.Computer-aided manufacturing (CAM) can be defined as the use of computer systems to plan, manage, and control the operations of a manufacturing plant through either direct or indirect computer interface with the plant’s production resources. As indicated by the definition, the applications of computer-aided manufacturing fall into two broad categories: 1. Computer monitoring and control. 2. Manufacturing support applications. The distinction between the two categories is fundamental to an understand-ing of computer-aided manufacturing.In addition to the applications involving a direct computer-process interface for the purpose of process monitoring and control, computer-aidedUnit 1Modern Design and Manufacturing 3manufacturing also includes indirect applications in which the computerserves a support role in the manufacturing operations of the plant. In theseapplications, the computer is not linked directly to the manufacturing process.Instead, the computer is used “off-line” to provide plans, schedules, forecasts,instructions, and information by which the firm’s production resources can bemanaged more effectively. The form of the relationship between the computerand the process is represented symbolically in the figure given below. Dashedlines are used to indicate that the communication and control link is an off-lineconnection, with human beings often required to consummate the interface.However, human beings are presently required in the application either toprovide input to the computer programs or to interpret the computer outputand implement the required action.CAM for manufacturing supportN EW W ORDS AND E XPRESSIONScategory /5kAtI g ErI/ n.分类component /kEm5pEJnEnt/ n.部分，配件，部件consummate /5k S nsQmeIt/ v.使圆满，使完成define /dI5faIn/ v.界定，给…下定义digital /5dIdVItl/ a.& n.数字(的)distinct /dI5stINkt/ a.清楚的distinction /dI5stINkFEn/ n.区别，差别dynamic /daI5nAmIk/ a.动力的；动态的effectively /I5fektIvlI/ ad.有效地facilitate /fE5sIlIteIt/ v.使容易，使便利，促进implement /5ImplImEnt/ v.实现；执行input /5Input/ v. & n.输入integrate /5IntI5greIt/ v.使完整，使一体化integration /IntI5greIFEn/ a.一体化interface /5IntEfeIs/ n.界面，接口interpret /In5tE:prIt/ v. 解释，说明4keyboard /5ki:5bR:d / n.键盘modification /m S dIfI5keIFEn / n. 修改，更改 off-line /5S f laIn / ad.脱机 optimization /S ptImaI5zeIFEn / n.最佳化，优化 output /5aJtpJt / v. & n. 输出E n g l i s h f o r M e c h a n i c a l & E l e c t r i c a l E n g i n e e r i n gstrain /streIn / n.应变 stress /stres / n.压力，应力 symbolically /sIm5b S lIkElI / ad. 象征性地 terminal /5tE:mInl / n. 终端ultimately /5QltImItlI / ad. 最后，最终；最重要的是 give rise to引起，使发生 move in the direction of 朝…方向移动/发展 provide for 提供Check Your UnderstandingI.

12 Fig 2.2 Function y=logx
13
A is the compression coefficient and the curve is continuous at x = 1/A．The law is illustrated in Fig 2.3.
14 Fig 2.3 Cattermoles’s compandingng To obtain compression of the large amplitude signals, a logarithmic law would seem appropriate．Unfortunately, as we can see from Fig 2.2, the function y = log x does not pass through the origin．It is therefore necessary to substitute a linear portion to the curve for lower values of x．Most practical companding systems are based on suggested by K.W.Cattermole, namely．
15
The practical implementation of this law would require nonlinear signal processing followed by linear quantization．The implementation of the nonlinearity, together with the complementary nonlinearity at the receiver, presents considerable problems．It is usual, therefore, to implement a piece-wise linear segmental approximation to the law．Two piece-wise linear laws are in general use．That used in Europe is known as the CCITT companding law A．A-law companding consists of eight linear segments for each polarity, the slope halving for each segment, except for the lowest two segments．The law is illustrated in Fig 2.4．
