Abstract：

Directed at the difficulty of springback evaluation of punching parts with complex surfaces and without reference points, an evaluation method was proposed based on simulation computing, reverse engineering technology and reverse loading model. Firstly, springback reference point of stamping parts was determined by simulation and the feasibility was verified by experiments. Secondly, reverse engineering technology was used to reconstruct surface after springback. The reconstructed surface and the original surface were used to establish reverse loading model. According to the elastic deformation characteristics, the correspondence of each node on reconstructed surface and original one was established to obtain the springback value of each node, and the springback evaluation of punching parts with complex surfaces was realized. The examples demonstrate that the method provides an evaluation approach for springback of punching parts with complex surfaces.
