FE-SIMULATION AND ANALYSIS OF FRICTION CONDITIONS IN THE DEEP DRAWING TEST
The friction conditions in the deep drawing process are a major factor affecting the amount of the punch force, the tools wear and also the product surface quality. This paper presents an analysis of the influence of friction conditions on the punch force in deep drawing test of a cylindrical cup. For this a finite element model for simulation of deep drawing test was build. The variables in this study were the coefficient of friction between blank and tools and the blank holder force. A DC06 cold rolled steel sheet with 1 mm thickness is considered in this study.Key words: Deep drawing test, Friction conditions, FE-Simulation, Punch force, Blank holder force.
