Numerical prediction of punch wear in the context of blanking process of copper alloy thin sheet
Résumé
Through the study presented here, we want to identify how the simulation of the blanking process could reduce defects of production, improve punches life and assist in the progression and control of the process. This was carried out with using software LS-DYNA. Based on the results obtained by simulation of blanking operation in two dimensions, we can predict the evolution of the gradual wear of active parts of punch according to the number of press strokes; by developing a calculation algorithm based on the Archard law of wear.
