Abstract

In the stamping process, springback causes geometrical inaccuracies in the final shape of metal stampings. Springback behavior is highly influenced by mechanical properties of the material, by the geometrical complexity of the shape and also by stamping process itself. In reality, it is very difficult to predict to which extent springback occurs. That is the reason, why numerical simulations are used more commonly nowadays (AutoForm, PAM-STAMP, etc.). This research focuses on the creation and application of the springback compensation strategy with the goal of minimalize the springback phenomenon in the field of stamping processes. Especially in automotive (in the production of car body parts) where springback became an often debatable and significant topic. For the verification and validation of the strategy, car body parts from VW Group were used, namely SEAT Ateca inner and outer fifth doors and ŠKODA Superb fender. Proposed strategy was designed in the cooperation with the Pressing tools design department in ŠKODA AUTO.

Keywords: springback, numerical simulation, AutoForm, forming, deep drawing.
