Abstract

A drawback of former wear simulation of deep drawing processes is that the change of wear caused by increasing the number of punch strokes was not considered. Geometry-Update-Scheme (GUS) which has been proposed at Institute of Metal Forming and Casting considers the changes of tool geometry caused by wear through interactive iterations of forming and wear simulation. The wear depth from simulation using GUS shows maximal 0.07 mm of difference from the measurement at a section of worn die-geometry. In this study, only the abrasive wear was considered.
