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.

The micrometer screw gauge also uses an auxiliary scale (measuring hundredths of a millimeter) which is marked on a rotary thimble. Basically it is a screw with an accurately constant pitch. The micrometers in our laboratory have a pitch of 0.50 mm. The rotating thimble is subdivided into 50 equal divisions. The thimble passes through a frame that carries a millimetre scale graduated to 0.5 mm. The jaws can be adjusted by rotating the thimble using the small ratchet knob. The thimble must be rotated through two revolutions to open the jaws by 1 mm. Here is a useful applet to learn how to use the micrometer screw gauge (Figure 1-19).Figure 1-19 The micrometer screw gaugeIn order to measure an object, the object is placed between the jaws and the thimble is rotated using the ratchet until the object is secured. Note that the ratchet knob must be used to secure the object firmly between the jaws, otherwise the instrument could be damaged or give an inconsistent reading.Note that an additional half scale division (0.5 mm) must be included if the mark below the main scale is visible between the thimble and the main scale division on the sleeve. The remaining two significant figures (hundredths of a millimeter) are taken directly from the thimble opposite the main scale.In Figure 1-20 the last graduation visible to the left of the thimble is 7 mm and the thimble lines up with the main scale at 38 hundredths of a millimeter (0.38 mm); therefore the reading is 7.38 mm.In Figure 1-21 the last graduation visible to the left of the thimble is 7.5 mm; therefore the reading is 7.5 mm plus the thimble reading of 0.22 mm, giving 7.72 mm.Figure 1-20 The reading is 7.38mm Figure 1-21 The reading is 7.27mm In Figure 1-22 the main scale reading is 3 mm while the reading on the drum is 0.46 mm; therefore, the reading is 3.46 mm.In Figure 1-23 the 0.5 mm division is visible below the main scale; therefore the reading is 3.5 mm + 0.06 mm = 3.56 mm.Figure 1-22 The reading is 3.46mm Figure 1-23 The reading is 3.56mm Try the following bg yourselfFigure 1-24 Figure 1-25 Figure 1-26A: Do exercise 1, 2, 3, 4 and 7.AssignmentB: Ask students to collect some external machine tools.《机电一体化专业英语》授课计划_ _______ 学院___ 专业班20 －20 学年第学期授课时间：第周Key Points unit.2.

To get the work properly centered, close the jaws until they just touch the surface of the work, then rotate the work-piece by hand in the jaws to seat it; then tighten the jaws (Figure 2-17). Beginning the Facing CutUse the pound handwheel to advance the tip of the tool until it just touches the end of the work-piece. Use the cross feed crank to back off the tool until it is beyond the diameter of the work-piece. Turn the lathe on and adjust the speed to a few hundred RPM — setting of the speed control knob. Now slowly advance the cross feed hand-wheel to move the tool towards the work-piece. When the tool touches the work-piece it should start to remove metal from the end (Figure 2-18). Continue advancing the tool until it reaches the center of the work-piece and then crank the tool back in the opposite direction (towards you) until it is back past the edge of the work-piece (Figure 2-19).Figure 2-18 Figure 2-19 Since we started with the tool just touching the end of the work-piece, you probably removed very little metal on this pass. This is a good idea until you get used to how aggressively you can remove metal without stalling the lathe.The Roughing CutUse the pound crank to advance the tool towards the chuck about 0.010". If the pound is set at a 90 degrees to the cross slide (which is how I usually set mine) then each division you turn the crank will advance the tool 0.001 (one-thousandth of an inch) toward the chuck.If the pound is set at some other angle, say 30 degrees, to the cross slide, then it will advance the tool less than 0.001 for each division. The exact amount is determined by the trigonometric sine of the angle. Here’s a picture of the first pass of a facing operation (Figure 2-20).Cutting on the Return PassIf you crank the tool back towards you after it reaches the center of the work-piece you will notice that it removes a small amount of metal on the return pass. This is because the surface is not perfectly smooth and it is removing metal from the high spots. If you need to remove a lot of metal, to reduce the work-piece to a specific length, for example, you can take advantage of this return cut to remove more metal on each pass by advancing the tool a small ways into the work-piece on the return pass. Since the tool must plunge into the face of the work-piece, this works best with a fairly sharp pointed tool.The Finishing CutDepending on how rough the end of the work-piece was to begin with and how large the diameter is, you may need to make three or more passes to get a nice smooth finish across the face. These initial passes are called roughing passes and remove a relatively large amount of metal.When you get the face pretty smooth you can make a final finishing cut to remove just 0.001 to 0.003" of metal and get a nice smooth surface. Figure 2-21 shows removingabout 0.002" of metal at around 1 000 RPM. Figure 2-22 shows the finished face of thework-piece.　Figure 2-21 Figure 2-22Figure 2-23 shows what happens if the tip of your cutting tool is below the center line of the lathe — a little nub is left at the center of the work-piece. The same thing happens ifthe tool is too high but the nub will have more of a cone shape in that case. If the tool is toolow, place a suitable thickness of shim stock underneath the tool in the tool holder. If it’s toohigh, grind the top down a few thous.Filing the EdgeFacing operations leave a rather sharp edge on the end of the work-piece. It’s a good idea to smooth this edge down with a file to give it a nice chamfer and to avoid cuttingyourself on it. With the lathe running at fairly low speed, bring a smooth cut file up to theend of the work-piece at a 45 degree angle and apply a little pressure to the file. Figure2-24: Right — left hand holding tang end of file. Figure 2-25: Wrong — left hand reachingover spinning chuck!Figure 2-23 Figure 2-24Figure 2-26 shows the finished surface and beveled edge. This is what a good facing cut should look like: smooth even surface with no raised bump in the center.　Lay anaccurate straight edge across the surface of the face and you should not be able to seeany light under the edge. If you detect a slight convex shape, the carriage may be movingback away from the headstock during the cut.Figure 2-25 Figure 2-26A: Do exercise 1, 2, 3, 4 and 7.AssignmentB: Ask students to collect some external machine tools.《机电一体化专业英语》授课计划_ _______ 学院___ 专业班20 －20 学年第学期授课时间：第周教学难点Difficult Points 1.

Unit11 Rapid Prototyping and Manufacturing Technologies 快速成型与制造技术Introduction 导言Manufacturing community is facing two important challenging tasks: Substantial reducition of product development time; and Improvement on flexibility for manufacturing multi-variety and small batch-size products. Computer-aided design and manufacturing(CAD and CAM) have significantly improved the traditional production design and manufacturing. However, there are a number of obstacles in true integration of computer-aided design with computer-aided manufacturing for rapid development of new prodcts.制造社会面临两个重要的富有挑战性的任务：大幅度减少产品开发时间，提高多种产品，小批量大小产品的制造灵活性。

计算机辅助设计与制造(CAD 和CAM)有着显著改善了传统的产品设计及制造。

然而，在新产品快速开发方面有一些障碍，这些障碍阻碍着计算机辅助设计与计算机辅助制造的真正集成。

To substantially shorten the time for developing patterns, moulds, and prototypes, some manufacturing enterprise have started to use rapid prototyping(RP) methods for complex partterns making and component prototyping. Over the past few years, a variety of new rapid manufacturing technologies, generally called Rapid Prototyping and Manufacturing(RP & M) have emerged; the technologies developed include stereo lithography(SL),selective laser sintering(SLS), fused deposition modeling(FDM), laminated object manufacturing(LOM), and three dimensional printing(3D Printing). These technologies are capable of directly generating physical objects from CAD databases. They have a common important feature: the prototype part is produced by adding materials rather than removing materials, that is , a part is first modeled by a geometric modeler such as a solid modeler, and then is mathematically sectioned(sliced) into a series of parallel cross-section pieces. For each piece, the curing or binding paths are generated. These curing or binding paths are directly used to instruct the machine for producing the part by solidifying or binding a line of material. After a layer is built, a new layer is built on the previous one in the same way. Thus, the model is built layer by layer from the bottom to top.为了大大缩短母模，模具和样件的制作时间，一些制造厂开始利用快速原型制造技术(RP)来制作复杂的母模和零部件的原型。

2. Principles of Plastic Forming Plasticity theory is the foundation for the numerical
treatment of metal forming processes. Materials science and metallurgy can explain the origins of the plastic state of metallic bodies and its dependence on various parameters，such as process speed，prior history，temperature. The essentially older plasticity theory deals with the calculation of stresses，forces，and deformation.

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.
