ABSTRACT
The restrike operation is very important for keeping the shape and quality of stamped parts stable. This study looks at how restrike helps in the stamping process by fixing issues like spring back and surface quality. The first part of the study shows why restrike is needed to prevent problems such as cracks or too much thinning that can happen when making certain parts. This was done using simulations on an outer reinforcement with Auto Form. The second part shows how restrike helps improve spring back. Two simulations were done on different parts using Auto Form: the side member and the rear wheel arch. An experiment was also carried out to support the findings. The results show that restrike greatly reduces spring back and helps fix thinning and cracking problems.
