Influence of Relative Clearance to Hole Quality in Punching Process

Abstract:

Influence of relative clearance to hole quality is investigated by numerical simulation and experiment. The numerical simulation in punching process of sheet metal is conducted by using ANSYS/LS-DYNA.The relative clearances in two sizes are selected to investigate the difference of holes cross section. Influence regularity of the relative clearance to hole quality is obtained by experimental investigation.
