Improvements in Springback Calculation and Die Compensation taking into account Buckling, Bottoming and Shape Control

This paper looks into the problem of instability during the springback and the bottoming effect. The aim is to improve the overall quality of the die compensation. Also in this paper we look into how to improve the surface quality of successful die compensation by introducing “shape control” – allowing the management of shape control during compensation, particularly important for external panels with design constraints.
