Development and validation of a new method for accelerated and economic wear testing of tool materials for deep drawing applications

摘要

This publication describes a new quick and economical method for the simulation of tool wear in the deep drawing and stretch forming of steel sheets in the area of the drawn edge. This method also allows a comparative evaluation of the properties of different tool materials versus reference materials. In order to reduce the amount of required test cycles, a controlled amount of wear inducing particles is added to the contact zone between tool and sheet metal.
