摘　　要：对存在干涉问题的复杂零件的逆向工程实现技术进行了深入研究。提出了不同于铣削层去法的机械去除测量方法,对零件的数字化、数据点云的重定位以及三维重构的全过程进行了详细地阐述,并对逆向工程整个过程存在的误差进行了分析和计算,确保了逆向工程的整体精度。Realization technologies for reverse engineering of complicated components, which are obstructed are studied thoroughly. A measurement method by mechanical cutting, which is different from milling slice removal, is put forward. The technologies such as digitization of parts, relocation of data points and the process of reverse engineering are explained. Lastly, the holistic precision is ascertained by analysis and calculation of errors existing in the process of reverse engineering.
