3、 Client Pro.Copyright 2004-2011 Aspose Pty Ltd.A coordinate measuring machine (CMM) is typically used to generate 3-D points from the surface of a part. Its digitizing a part in three dimensions. However, it is often used to make 2-D measurements such as measuring the center and radius of a circle i

4、n a plane, or even one-dimensional measurements such as determining the distance between two points. Typically, CMMs are configured to measure in Cartesian coordinates.11. configure 意為“為特定設(shè)備或用途而進(jìn)行的設(shè)計(jì)”。全句可譯為：通常，三坐標(biāo)測量機(jī)是專門為在直角坐標(biāo)系內(nèi)進(jìn)行測量而設(shè)計(jì)的。機(jī)械工程專業(yè)英語教程7/18/2022Text tour4Evaluation only.Created with Aspose

5、.Slides for .NET 3.5 Client Pro.Copyright 2004-2011 Aspose Pty Ltd.CMMs are manual or automatic. In manual mode, the CMM is moved by the user. An automatic CMM is typically actuated byelectric drives (using ballscrews or linear motors).22. electric drive 意為“電氣傳動，又稱電力拖動。生產(chǎn)過程中，以電動機(jī)作為原動機(jī)來帶動生產(chǎn)機(jī)械，并按所給定的規(guī)

6、律運(yùn)動的電氣設(shè)備”。全句可譯為：一個自動化的三坐標(biāo)測量機(jī)通常采用電氣傳動的方式（通過滾珠絲杠或采用直線電動機(jī)）。機(jī)械工程專業(yè)英語教程7/18/20225Evaluation only.Created with Aspose.Slides for .NET 3.5 Client Pro.Copyright 2004-2011 Aspose Pty Ltd.As shown in Figure 1, articulated arm CMMs look very much like six-degree-of-freedom robots, and are almost always manuall

7、y driven. Hybrid CMMs are a cross between articulated arm systems and traditional CMMs. They may have servo assist for making measurements.Figure 1 Articulated arm CMM機(jī)械工程專業(yè)英語教程7/18/20226Evaluation only.Created with Aspose.Slides for .NET 3.5 Client Pro.Copyright 2004-2011 Aspose Pty Ltd.New user-fr

8、iendly software that allows the CMM and probe to be accurately, quickly, and easily calibrated has also made the CMM more accurate and easier to use.3 3. user-friendly意為“用戶界面友好的，用戶容易掌握使用的”。全句可譯為：新的用戶界面友好的軟件可以對三坐標(biāo)測量機(jī)及其測量頭進(jìn)行精確、快速和容易的校準(zhǔn)工作，這也使得三坐標(biāo)測量機(jī)更為精確和更容易使用。As a result, looser tolerances can be used

9、on the system hardware, and the resulting errors (as long as they are highly repeatable) are eliminated in software.44. looser tolerance 意為“比較大的公差”。全句可譯為：結(jié)果是，系統(tǒng)硬件的公差可以比較大，只要可重復(fù)性很高，其所產(chǎn)生的誤差可應(yīng)通過軟件予以消除。機(jī)械工程專業(yè)英語教程7/18/20227Evaluation only.Created with Aspose.Slides for .NET 3.5 Client Pro.Copyright 2004-

10、2011 Aspose Pty Ltd.A controlled environment is important for efficient CMM operation. CMMs can operate well on the shop floor if they are equipped with thermal compensation capabilities that correct for temperature changes from standard temperature (20C).55. thermal compensation意為“熱補(bǔ)償”。全句可譯為：如果三坐標(biāo)測

11、量機(jī)具有熱補(bǔ)償能力，能夠在偏離標(biāo)準(zhǔn)溫度(20oC)時，對由于溫度變化帶來的影響進(jìn)行修正，三坐標(biāo)測量機(jī)就可以很好地在車間內(nèi)工作。 8機(jī)械工程專業(yè)英語教程7/18/2022Evaluation only.Created with Aspose.Slides for .NET 3.5 Client Pro.Copyright 2004-2011 Aspose Pty Ltd.A stationary bridge-type CMM is shown in Figure 2, and the accuracy of this kind of CMM is usually better than that of a m
