Abstract：

The spring-back phenomenon in automotive panel forming is one of the main quality problems,which may affect the tolerance and final shape of panel products.The stamping and spring-back process simulation for the automotive panel were realized by using the Dynaform software,emphasizing on the possibly spring-back quantity forecasted and the die surface was optimized to control spring-back.The reasonability of optimization scheme and veracity of simulation were proved by comparing the simulation result with the eligible part obtained.And it provides a significant guidance to the manufacture of the automotive panel dies.
