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 7.27mmIn 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 1-26 A: Do exercise 1, 2, 3, 4 and 7.《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The following is the vice jaw structures.Explanations of the Vice Jaw TermsNo. Name Explanation1 Fixed jaw 固定钳口2 Hardened and ground 已硬化和磨光3 Special angle-lock system 特制的角锁紧系统4 Vice body 虎钳体5 Adjusting stop ring 调整止动环6 Clamping force 夹紧力Milling Machine (铣床)1. ________ (升降台铣床)2. ________(龙门铣床)3. ________ (单臂铣床 )4. ________（仪表铣床）5. ________（工具铣床）6. ________ (单柱铣床)Single-column Milling Machine Plano-milling Machine Tool Milling MachineSample 1（实践部分）Explanations of TermsName ExplanationOuter frame 外框Scale mark plate 刻度盘Spring 弹簧Arm 测量臂A B1.

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 crossfeed hand-wheel to move the tool towards thework-piece. When the tool touches the work-piece itshould 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 2-19Since 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 compound crank to advance the tool towards the chuck about 0.010". If the compound 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 compound 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 firs t pass of a facing operation (Figure 2-20).Cutting on the Return PassIf you crank the tool back towards you after itreaches 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 fairlyFigure 2-17Figure 2-20sharp 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 removing about 0.002" of metal at around 1 000 RPM. Figure 2-22 shows the finished face of the work-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 if the tool is too high but the nub will have more of a cone shape in that case. If the tool is too low, place a suitable thickness of shim stock underneath the tool in the tool holder. If it’s too high, 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 cutting yourself on it. With the lathe running at fairly low speed, bring a smooth cut file up to the end of the work-piece at a 45 degree angle and apply a little pressure to the file. Figure 2-24: Right —left hand holding tang end of file. Figure 2-25: Wrong —left hand reaching over 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 y an accurate straight edge across the surface of the face and you should not be able to see anylight under the edge. If you detect a slight convex shape, the carriage may be moving back away from the headstock during the cut.Figure 2-25 Figure 2-26A: Do exercise 1, 2, 3, 4 and 7.《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The following is the machine tool structure.No. Name Explanation1 Forward/Reverse 正转/反转2 Start/Stop 启动/停止3 Longitudinal Hand-wheel 纵向手轮4 Vertical Feed Hand-crank 垂直进给手柄5 Cross-Feed Hand-wheel 横向进给手轮6 Power Feed 电动进给7 Table 工作台Boring Machine (镗床)1. ________ (卧式铣镗床)2. ________(立式金刚镗床)3. ________ (双坐标镗床)4. ________（深孔镗床）5. ________（数控龙门镗铣床）Double Boring Machine Vertical Diamond Fine Boring Machine Boring MachineTypical parts programNo. Name Explanation1 twist bits 麻花钻2 tang 扁尾3 taper shank 锥柄4 point angle 顶尖角5 tang drive 扁尾驱动6 flutes 韧带7 helic angle 螺旋角8 lip-relief angle 刃倾角9 edge angle 横刀倾角10 drill diameter 钻头直径11 body diameter clearance 刀体直径间隙12 clearance diameter 间隙直径13 straight shank 直柄14 neck 颈部15 shank diameter 刀柄直径16 shank length 刀柄长度17 flute length 韧带长度18 body 刀体19 overall length 总长20 margin 刃边21 lip 刀刃22 web 钻心23 chisel edge 横刃A B1.

Turning is used to reduce the diameter of the work-piece, usually to a specified dimension, and to produce a smooth finish on the metal.Chucking the Work-pieceWe will be working with a piece of 3/4" diameter 6061 aluminum about 2 inches long. We can safely turn it in the three jaw chuck without supporting the free end of the work.Insert the work-piece in the three-jaw chuck and tighten down the jaws until they just start to grip the work-piece. Rotate the work-piece to ensure that it is seated evenly and to dislodge any chips. You want the work-piece to be as parallel as possible with the center line of the lathe. Imagine an exaggerated example where the work-piece is skewed at an angle in the chuck and you can easily visualize why this is important. Tighten the chuck using each of the three chuck key positions to ensure a tight and even grip (Figure 3-13).Adjusting the Tool BitChoose a tool bit with a slightly rounded tip. This type of tool should produce a nice smooth finish. Adjust the angle of the tool-holder so the tool is approximately perpendicular to the side of the work-piece. Because the front edge of the tool is ground at an angle, the left side of the tip should engage the work, but not the entire front edge of the tool. The angle of the compound is not critical. I usually keep mine at 90 degrees so that the compound dial advances the work (Figure 3-14).Figure 3-13Figure 3-14Cutting SpeedsYou must consider the rotational speed of the work-piece and the movement of the tool relative to the work-piece. Working with the 7×10 for hobby purposes, you will quickly develop a feel for how fast you should go.Until you get a feel for the proper speeds, start with relatively low speeds and work up to faster speed. Most cutting operations on the 7×10 will be done at speeds of a few hundred RPM —with the speed control set below the 12 o'clock position and with the HI/LO gear in the LO range.Turning with Hand FeedAs always, wear safety glasses and keep your face well away from the work since this operation will throw off hot chips and/or sharp spirals of metal.Now advance the cross slide crank about 10 divisions or 0.010". Turn the carriage hand-wheel counterclockwise to slowly move the carriage towards the headstock. As the tool starts to cut into the metal, maintain a steady cranking motion to get a nice even cut. It’s difficult to get a smooth and even cut turning by hand (Figure 3-15).Continue advancing the tool towards the headstock until it is about 1/4" away from the chuck jaws. Obviously you want to be careful not to let the tool touch the chuck jaws (Figure 3-16)!Figure 3-15 Figure 3-16Turning with Power FeedOne of the great features of the 7×10 is that it has a power lead-screw driven by an adjustable gear train. The lead-screw can be engaged to move the carriage under power for turning and threading operations.To change the lever setting, you must pull back on the knurled sleeve with considerable force. With the sleeve pulled back you can move the lever up and down to engage its locking pin in one of three positions. In the upper position the lead-screw rotates to move the carriage towards the headstock and in the lower position the lead-screw moves the carriage away from the headstock (Figure 3-17).In the down position, the half-nut lever engages two halves of a split nut around the lead-screw. Make sure the half-nut lever is in the disengaged (up) position. Turn the motor on. The lead-screw should now be rotating counterclockwise (Figure 3-18). When the lead-screw is engaged the gear train makes kind of an annoying noise, but you’ll get used to it. Lubricating the gear train with white lithium grease will cut down some on the noise.Figure 3-17 Figure 3-18Just as in facing, you normally will make one or more relatively deep (0.010～0.030) roughing cuts followed by one or more shallow (0.001～0.002) finishing cuts. Of course you have to plan these cuts so that the final finishing cut brings the work-piece to exactly the desired diameter (Figure 3-19).When cutting under power, you must be very careful not to run the tool into the chuck.Measuring the DiameterIt is important to recognize that, in a turning operation, each cutting pass removes twice the amount of metal indicated by the cross slide feed divisions. Therefore, when advancing the cross slide by 0.010", the diameter is reduced by 0.020".The diameter of the work-piece is determined by a caliper or micrometer. Micrometers are more accurate, but less versatile. You will need a machinist's caliper capable of measuring down to 0.001". Vernier calipers do not have a dial and require you to interpolate on an engraved scale (Figure 3-20).Figure 3-19 Figure 3-20Turning a ShoulderA shoulder is a point at which the diameter of the work-piece changes with no taper from one diameter to the other.We will make a shoulder on our work-piece by reducing the diameter of the end of the work-piece for a distance of about 1/2" (Figure 3-21). Advance the cross slide about 0.020 and use power feed to turn down about a 1/2" length on the end of the work-piece. Repeat this a few more times until you have reduced the diameter of the end section to about 1/2" (Figure 3-22).Since the tip of the tool is rounded, the inner edge of the shoulder takes on a rounded profile.Now we will use this pointed tool to make a square finishing cut into the corner of the shoulder. Since this is such a short distance, we will use hand feed, not power feed. You can use hand feed with the lead-screw turning —just don’t engage the half-nut (Figure 3-23).To get a nice square face on the shoulder you will need to make a facing cut. This works best if you have made a carriage lock on your lathe. Lock the carriage and clean up the face of the shoulder until it is square. If you use the sharp pointed tool you will need to use fairly high RPM, say 1500, and advance the tool slowly or you will get little grooves from the pointed tip instead of a nice smooth finish.Finally, you may want to use a file as described in the facing section to make a nice beveled edge on outside edge of the shoulder and on the end of the work-piece (Figure 3-24).Figure 3-21 Figure 3-22Figure 3-23 Figure 3-24A: Do exercise 1, 2, 3, 4 and 7.《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The following is the structure of a regenerative hydraulic control.Explanations of the Mechatronics Terms No. Name Explanation1 Regenerative Hydraulic Control 回馈式液压控制2 Kidney Loop Filtration System 肾形环过滤系统3 Oversized Guide & Bushings 大型导杆和导套4 Ram Speeds to Spec. 专业滑块5 Stroke, Shut Height to Spec 上滑块的最大行程6 Daylight to Spec 规格孔距7 Ram Guide Bellows 波纹式防护罩8 Bolsters Machined to Spec 标准定位板1. 2. 3. 4.5. 6. 7. 8.9. 10.Flywheel Clutch and Brake Eccentric Shaft Connection Press Bed Slide (Ram) Shut Height Adjustment Bolster Counterbalance Cylinder Saddle Bushing Opposed Helical Gears at Each Side of Press（实践部分）The following is a lathe accessory, and you can understand the name of Bench Grinder.Explanations of TermsNo. Name Explanation1 Adjustable Tongue Guard 可调整的舌形护罩Match the words or phrases on the left with their meanings on the right.Bench Grinder1.

The temperature of metals being cold forged may range from room temperature to several hundred degrees.Open-die Forging is performed between flat dies with no precut profiles in the dies. Movement of the work-piece is the key to this method. Larger parts over 20 tones and 10 meters in length can be hammered or pressed into shape in this way.Seamless Rolled Ring Forging is typically performed by punching a hole in a thick, round piece of metal (creating a donut shape), and then rolling and squeezing (or in some cases, pounding) the donut into a thin ring. Ring diameters can be anywhere from a few inches to 30 feet.Process detailsClosed-die forgingA heated blank is placed between two halves of a die (Figure 4-15).A single compressive stroke squeezes the blank into the die to form the part. In hammer or drop forging this happens by dropping the top of the mould from a height. An alternative is to squeeze the moulds together using hydraulic pressure (Figure 4-16).Figure 4-15 Figure 4-16Once the die halves have separated, the part can be ejected immediately using an ejector pin (Figure 4-17).The waste material, flash, is removed later (Figure 4-18).《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The following is the common internal grinding machine.Explanations of the TermsNo. Name Explanation1 work head 头架2 cooling pipe 冷却管3 work table 工作台4 bed 床身5 oil pointer 油标6 feed handle 进给手柄7 longitudinal hand wheel 纵向手轮8 manipulating panel 操纵盘9 cross hand wheel 横向手轮10 slide saddle 滑鞍11 grinding carriage 砂轮架12 grinding wheel 砂轮13 bedside lamp 床头灯14 fixture device 夹具The following are some Functions on Mechatronics Terms.Grinding Machine（磨床）1. ________（内圆磨床）2. ________（平面磨床）3. ________（导轨磨床）4. ________（无心磨床）5. ________（工具磨床）6. ________（坐标磨床）Surface- Grinding Machine Centerless Grinding Machine Internal rinding Machine Jig Grinding Machine Slideway Grinding Machine Too Grinding Machine试试身手（实践部分）Period 2 Have a TryThe following is panel of a CNC machine, and you can understand the functions of its buttons.Explanations of the CNC PanelNo Name Explanation1 Alphabetic keyboard for enteringtexts and file names, as well as forprogramming in ISO format字母键盘用于输入文本及文件名称，也可按ISO格式进行编程2 ●File management●Pocket calculator (not TNC410)●MOD functions●HELP functions●文件管理●便携式计算器（并不是TNC 410型）●模式功能●辅助功能3 Programming modes 编程模式4 Machine operating modes 机床操作模式5 Initiation of programming dialog 可进行对话编程6 Arrow keys and GOTO jumpcommand箭头键和跳转指令7 Numerical input and axisselection数字输入和轴选择Match the words or phrases on the left with their meanings on the right.Automatic Tool Magazine（实践部分）Kow to Produce New Firebox Door PatternsThese are two of the old foundry patterns for our firebox doors. They are epoxy castings mounted in a plywood plate (Figure 5-20). The foundry switched to a new high pressure sand molding process, and the patterns broke (Figure 5-21). We needed higher strength aluminum patterns.Figure 5-20 Old foundry patterns Figure 5-21 New door to be designedBecause the old patterns were cast from a hand-made master, there were also problems such as dimensional inconsistencies, etc. The first step in building new patterns was to have a new vertical CNC milling machine (Figure 5-22).Figure 5-22 CNC Milling MachineNext, the doors were modeled in a Rhino, a new 3-D modeller. Here’s a screenshot of the Rhino model (Figure 5-23).Figure 5-23 3D modelHere’s a close-up of the parting line around the bottom hinge lug (Figure 5-24).Here’s a new feature in Rhino 1.1 Beta (Aug 20): Draft Angle Analysis (Figure 5-25).Figure 5-24 Figure 5-25Next, the 3-D Rhino model was imported into Visual Mill, a new CAM package that generates the cutter paths for the milling machine directly from Rhino NURBS models. Here is a screen shot of Visual Mill simulating the cutting of an aluminum block (Figure 5-26).Here’s another screen shot showing the tool-paths for a 1/8" ball shaped cutter as it goes into the corners around the hinges to clean up the leftovers from the previous larger cutter (Figure 5-27).Tool-paths were loaded onto a floppy disk and transferred to the mill’s controller. First, they were tested on a block of wax (Figure 5-28).Next, they were cut from a 2 1/4" thick block of aluminum. It takes about 12 hours of machine time to cut each side of a two-sided pattern.Here’s a photo of the finished patterns and their mounting plates (Figure 5-29).Figure 5-26 Figure 5-27Figure 5-28 Figure 5-29Figure 5-30A: Do exercise 1, 2, 3, 4 and 7.《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：第周机床构造Section II Glance at MachineTool StructuresPeriod 1 The following is the structure of the CNC machining center.Explanations of the TermsNo. Name Explanation1 DC servo motor 直流伺服电机2 manipulators for tool changing 换刀机械手3 control cabinet 控制柜4 plate-type tool changer 盘式刀库5 spindle carrier 主轴箱6 control panel 控制面板7 electrical cabinet 驱动电源柜8 table 工作台9 slide saddle 滑座10 bed 床身The following are some Functions on Mechatronics Terms.1. ________（数控车床）。

（2）选词要准确，英文中同义词不少，又如， safety 与 security 两词，虽然都可以作安全讲，但其含义是有所不同 的。safety 是安全、平安的意思，可指自身安全、使用产品的安全等， 如安全保险措施(safety precautions)、 （汽车）安全带（safety belt） 、安 全阀 （safety valve） 、 安全岛 （safety island） 、 安全运行 （safety operation） 等。而 security 则是安全、保护、保障的意思，如养老金的保障、 （防 盗）安全措施、保安措施均用 security 一词，又如国家的防卫、保安 部队、保安车（如押送金钱的）等。 写作过程中碰到选词有困难时，应充分利用词典的帮助。 B：简练 可将其拆为两句话： A safe, reliable and inexpensive device is really required between the transmission line and the consuming apparatus. It can convert the high voltage and low current of the economical transmission of the economical transmission line into the low voltage and high current required by the consuming apparatus. （2）精炼: 许多简单句子只要能压缩，应尽量去掉多余的词，例如: The English Language is about one-half redundant. （英语中约有一半是多余的。 ） 可以更精炼为： English is half redundant. 精炼可以提高信息密度，对写英文摘要尤其重要。 C：清晰
