In shearing, the crack occurrence may be controlled by elevating a hydrostatic pressure of a material near tool cutting edges. In the progressive die forming, shearing phenomena is affected by pre-punching station. Then the influence of pre-punching on shearing characteristics was investigated by the experiments and FEM analysis. The results of this study clarified the followings. With increasing of diameter of pre-punched hole, die side crack earlier occurs and punch side crack later occurs. This tendency agrees with the magnitude of hydrostatic pressure at punch and die cutting edges. Change of hydrostatic pressure mainly depends on decreased rigidity of pre-punched hole material to be sheared. It was also ascertained that the counter punch mainly affects the punch side crack occurrence.
