三坐标测量（接触法）典型测量零件的设计
摘要：随着CAD/CAM软件加工及快速成型等先进制造技术的不断发展，以及这些技术在机械行业中的普及应用，机械设计与制造领域正发生着一场深刻的技术革命，传统的二维设计及模拟量加工方式正逐步被基于产品三维数字化定义的数字化制造方式所取代。在这场技术革命中，逐步掌握三维CAD/CAM软件的使用，并用于数字化的设计与制造是其中的关键。
 三坐标测量机(CMM)则是一种高效率、高精度、多功能的检测设备。七十年代以来在测量机上广泛应用电子计算机后，它的性能和自动化程度都大为提高,使用范围也更广泛。昔日三坐标测量机主要面向航空航天等高技术产业，而今日，它在现代制造业的各个领域中都得到了广泛的应用，已成为机械制造业中发展最快的现代量仪之一。
 本文就是采用UG三维建模软件设计出基于三坐标测量技术能够进行测量的实体。然后把实体导入到AutoCAD 绘图软件，得到实体零件图。所设计出来的实体的曲面图形部分还要在微机上进行CAM仿真加工并通过后处理得到NC程序。然后利用三坐标测量机对现有类似零件进行检测。这样不仅能够较好的掌握UG的三维建模方法，AutoCAD 的绘图方式，还能熟悉三坐标测量机的操作环境。

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.
