摘要:随着社会的高度发展，人们对物质的要求越来越高，有工业方面正向设计越来越 难解决现有的问题，那需要大量的精力和时间。面对这样的问题，人们经过一系列的 努力，通过很多的试验，人们发现逆向工程设计无论在时间或精力上都比正向设计方 便。因此，逆向工程设计随之产生。本文详细介绍了逆向工程的相关概念和相关知识。 逆向工程是针对一现有工件(样品或模型,尤其适合复杂不规则的自由曲面),利用 3D 数字化测量仪器准确、快速地测量出轮廓坐标值,并构建曲面,经编辑、修改后,将数 据转至一般的 CAD/CAM 系统,再由 CAM 所产生刀具的 NC 加工路径送至 CNC 加工制作所 需模具、或者用快速成型机(rapidprotyping)将样品模型制作出来,这一流程称为逆向 工程。

　　　逆向工程技术是一门综合性技术包括：测量技术、数据处理技术、图形处理技术 和加工技术。每个环节都非常重要，每个环节的好坏直接影响到产品的质量。

　　　本文先讲述汽车离合器盖数据采集，主要讲述数据采集的基本方法和数据采集的 具体步骤；然后使用 solidworks 软件来构建实体，构造好的实体后，分析实体的精 度。

Abstract:With a highly developed society, people increasingly high demand for material, there is a positive design industry more and more difficult to solve existing problems, it requires considerable effort and time. Faced with this problem, one through a series of efforts, through many tests, it was found in terms of reverse engineering time or effort on design than being convenient. Therefore, the resulting reverse engineering. This paper describes the reverse engineering concepts and related knowledge. Reverse engineering is available for a piece (sample or model, especially suitable for complicated irregular free surface), using 3D digital measurement instruments rapidly and accurately measure the contour coordinates, and build the surface, edited, revised, will be data Go to general CAD / CAM systems, generated by the CAM NC tool path sent to the CNC machining process required in the production mold, or use the rapid prototyping machine (rapidprotyping) produced a sample model, the process known as reverse engineering.

　　　Reverse Engineering is a comprehensive technology include: measurement technology, data processing, graphics processing technology and processing techniques. Each link is very important that each link will have a direct impact on product quality.

　　　This paper describes the first clutch cover data collection, mainly about the basic methods of data collection and data acquisition of specific steps; then use solidworks software to build solid, the constructed entity, the analysis of physical accuracy.
