基于实物的复杂曲面产品反求工程中的CAD建模技术

基于零件实物样件的几何模型的反求已成为ＣＡＤ／ＣＡＭ领域中的一个研究热点，对目前国内外在复杂曲面产品反求工程中ＣＡＤ建模方面的研究现状做一较为简要的归纳。

CAD modeling in reverse engineering of complex surface products

Reverse Engineering(RE) is the technology relating to the main process of making models from real parts. They can be used in many purposes in modern product development. Technologies about CAD modeling from real parts have become a popular research field in CAD/CAM in foreign countries recently. These technologies typically start with digitizing existing objects so that surface or solid models can be deduced in order to exploit the advantages of CAD/CAM technologies. This paper has reviewed on methods that are used in CAD modeling from real objects at home and abroad in the last few years.
