CAE Modeling of Hot Stamping Tool Wear

To assess the wear of hot stamping tool, a model punch deformation under influence thermal and mechanical loads was developed. The shape relative position die were designed to localize maximum contact at predetermined location. It assumed that is caused by removal surface metal layer, due decreasing its strength during plastic deformation. Simulation performed finite element method in Deform software package. A temperature field pattern zone calculated. With respect typical for forging railway wheels, comparison showed numerical experiment same level as actual value wear.
