Abstract: Fine blanking die wear model for finite element analysis was built.Simulation was carried out in normal tem?perature for analyzing fine blanking punch wear by using the finite element software Deform?3D.The influences on the die wear by process parameters,such as die material hardness,coefficient of friction between blank and die,and the forming load were analyzed.The results show that the punch edge wear is serious,but the amount of wear in the convex side is small.The maximum wear depth is decreased with the increase of the hardness of die material,and increased with the in?crease of friction coefficient.The counterforce is also the important factor influencing the punch wear,the maximum wear depth is increased with the increase of the counterforce.
