How to determine the trimming contour is a very hard work.Many issues suggested some calculation methods of the cutting contour to resolve the work.However,these methods did not concern the springback so much,especially when there was a large springback.The results of these methods were not accurate.To solve the trimming contour for large springback parts,the deformation path iteration method's base arithmetic was researched and the modification of shape error volume for optimizing trimming line was analyzed.The basic methods to solve springback and calculation methods of the cutting contour for large springback were suggested.In order to verify the reliability of the results and the feasibility of the proposed method in engineering,a front bumper example was investigated.
