基于PRO/E的逆向工程研究与实践

Research of Reverse Engineering based on PRO/E

逆向工程,即对已有的零件或实物原型利用三维数字化测量设备准确,快速的测量出实物表面的三维坐标点,并根据这些坐标点通过三维几何建模方法重建实物CAD模型的过程.本文以Pro/ENGI-NEER WILDFIRE 4.0为平台,对基于Pro/E的逆向工程技术在创建鼠标实体模型中的应用进行了实验研究.

Reverse engineering is to extract the information from parts or physical object to reconstruct a CAD model for a particular purpose like redesign,reproduction or quality control. The three-dimensional coordinate~ points of the physical object surface are rapidly measured by 3D digitizing accurate measurement equipment. According to these coordinates, the rebuilding Real CAD model is applied in reverse engineering. In this paper, the Pro/ENGINEER WILDFIRE 4.0 are a platform, and reverse engineering technology based on Pro/E to create mouse entity model is investigated.
