反向工程中自由曲面的数字化检测

Digitized Inspection of Free-Form Surfaces in Reverse Engineering

基于离散数据点比较两个自由曲面对于反向工程是至关重要的 ,本文提出在其中应该进行三种类型的形状精度检测。建立了定量分析原型件和其制造件之间形状误差的方法 ,阐述了未知曲面数字化。

Comparison of two free-form surfaces based on discrete data points is of paramount importance for reverse engineering It is proposed that three types of dimensional inspection be done during reverse engineering A methodology for error analysis between a physical prototype and its manufactured part is established, and key technologies such as digitization of unknown surface, registration of surfaces without datums and eror calculation are discussed
