The paper puts forth that the numerical model of actual forming part is reconstructed by RE and the surface is regarded as actual trimmed surface, then grids and nodes mapping relationship between design model and actual forming part is acquired through compelling deformation simulation, and the design trimming line is dispersed into points according to a certain precision and the projective points and the coordinate values of the intersection points of projective line on the grids formed by discrete points are calculated along trimming direction, the new coordinate values of projective points and intersection points of projective line after deformation are calculated based on the mapping relationship of grids and nodes, the deformed trimming line can be acquired through fitting the points into curve.

本文提出通过逆向工程技术重构出实际冲压件的型面并以此型面为修边后实际冲压件的型面，然后采用强制变形仿真的方法建立设计模型和实际冲压件重构模型的网格和节点映射关系。将设计修边线按一定精度离散成点，然后根据修边方向计算出各点在网格上形成的投影点和投影线交点，根据之前计算出来的网格和节点映射关系就可以计算出投影点和投影线交点在变形后的新坐标，将其拟合成曲线就可以得到变形后修边线的形状。
