摘要
用接触法测量曲面获取其轮廓数据,采用准均匀B样条逼近算法对离散数据进行拟合,再将反求设计与正向设计结合起来,在Pro/E中重建曲面模型.
The data of surface is given by the CMM. The quasi-uniform B-spline approximation algorithm is used to fit the discrete data, then the data is transformed into the format of the *.ibl file of the Pro/E software, and the CAD model is reconstructed by taking full advantage of conventional design and reverse engineering.
