所谓逆向工程,其主要是指在缺失完整的设计图纸或者没有设计图纸和CAD模型时,以当前拥有的实物模型为参考,利用各种数字化扫描技术来重新构造产品样本的CAD模型。与此同时,还需要使用先进的CAD技术来制造、改进和修改产品的样本形状,从而使得模型产品可以被最终加工出来。利用逆向工程对复杂曲面进行数控加工是一种新型的加工技术,对其进行全面的分析和研究,对于促进相关产业的发展具有重要作用。
The so-called reverse engineering, mainly refers to the lack of complete design drawings or design drawings and CAD models, with the current physical model as a reference, using a variety of digital scanning technology to restructure the CAD model of the product samples. At the same time, advanced CAD technology is also needed to create, modify and modify the sample shape of the product so that it can be finalized. It is a new type of machining technology to reverse-engineer the complex surface by numerical control. It is of great importance to promote the development of related industries through comprehensive analysis and research.
