三坐標(biāo)測(cè)量（接觸法）典型測(cè)量零件的設(shè)計(jì)
摘要：隨著CAD/CAM軟件加工及快速成型等先進(jìn)制造技術(shù)的不斷發(fā)展，以及這些技術(shù)在機(jī)械行業(yè)中的普及應(yīng)用，機(jī)械設(shè)計(jì)與制造領(lǐng)域正發(fā)生著一場(chǎng)深刻的技術(shù)革命，傳統(tǒng)的二維設(shè)計(jì)及模擬量加工方式正逐步被基于產(chǎn)品三維數(shù)字化定義的數(shù)字化制造方式所取代。在這場(chǎng)技術(shù)革命中，逐步掌握三維CAD/CAM軟件的使用，并用于數(shù)字化的設(shè)計(jì)與制造是其中的關(guān)鍵。
 三坐標(biāo)測(cè)量機(jī)(CMM)則是一種高效率、高精度、多功能的檢測(cè)設(shè)備。七十年代以來在測(cè)量機(jī)上廣泛應(yīng)用電子計(jì)算機(jī)后，它的性能和自動(dòng)化程度都大為提高,使用范圍也更廣泛。昔日三坐標(biāo)測(cè)量機(jī)主要面向航空航天等高技術(shù)產(chǎn)業(yè)，而今日，它在現(xiàn)代制造業(yè)的各個(gè)領(lǐng)域中都得到了廣泛的應(yīng)用，已成為機(jī)械制造業(yè)中發(fā)展最快的現(xiàn)代量?jī)x之一。
 本文就是采用UG三維建模軟件設(shè)計(jì)出基于三坐標(biāo)測(cè)量技術(shù)能夠進(jìn)行測(cè)量的實(shí)體。然后把實(shí)體導(dǎo)入到AutoCAD 繪圖軟件，得到實(shí)體零件圖。所設(shè)計(jì)出來的實(shí)體的曲面圖形部分還要在微機(jī)上進(jìn)行CAM仿真加工并通過后處理得到NC程序。然后利用三坐標(biāo)測(cè)量機(jī)對(duì)現(xiàn)有類似零件進(jìn)行檢測(cè)。這樣不僅能夠較好的掌握UG的三維建模方法，AutoCAD 的繪圖方式，還能熟悉三坐標(biāo)測(cè)量機(jī)的操作環(huán)境。

The design of typical measurement component which based on the 3-Dimensional Measuring Technology
Abstract: With the development of advanced manufacturing technology, such as the CAD / CAM software processing and rapid prototyping, and the universal and application in the machinery industry of these technologies, a profound technological revolution has taking place in the field of mechanical design and manufacturing, the digital manufacturing methods which based on the 3D digital definition are gradually in place of the traditional 2-dimensional design and analog processing approach. Gradually master the use of 3D CAD / CAM software then used for the digital design and manufacturing is the key to this technological revolution.
 Coordinate Measuring Machine (CMM) is an inspection and measuring apparatus with a high accuracy, high efficiency and high performances. Since the 1970s,with the widely use of electronic computer on the measuring machine ,which performance and the degree of automation are improve ,and could using in a wider range. CMM mainly only used for aerospace and other high-tech industries, but today, its have been widely used in various fields of modern manufacturing industry .It has becoming fastest-growing one of the modern measuring instruments in machinery manufacturing.
 This article is used UG 3-dimensional modeling software to designing the entity which can be measured based on the 3-dimensional measuring technology .Then imported the entity into AutoCAD mapping software, and obtain the parts plans of the entity. Graphics of the surface ,which by the designed entity ,must to proceed CAM simulation processing and obtain NC program through after treatment in computer .Then use CMM to examination the similar existing parts. So we could not only to grasp the UG 3-D Modeling methods and the AutoCAD drawing methods, but also familiar with the CMM 's operating environment.
