In the shearing process, the amount of clearance greatly influences on the quality of product. Moreover, when the shearing tool has a complicated closed-contour, the amount of clearance is set at the different value by the place. Therefore, the load is not uniformly applied on punch head and side wall. In this study, shearing experiment and rigid plastic finite element simulation were carried out in the case of shearing with imbalanced clearance. As results, the load applied on punch, the distortion of product and the formation process of shearing face in the case of shearing with unequal clearance were clarified. Then, the effect of the imbalanced clearance on the quality of the shearing product was examined.
