In this paper, we discuss the clearance compensation effect in precision shearing. This effect is based on the hypothesis that an unbalanced clearance is automatically compensated for by punch bending when shearing is performed by a long and thin punch. In this paper, we discuss the compensating mechanism through various experiments and an elastic-plastic finite element method. The following results are obtained. When the clearances of the right and left sides are different, the shearing force and horizontal force acting on both punch sides are slightly different. These forces result in moments that bend the punch. The clearance compensation effect depends on the magnitude and direction of these moments. Namely, the effect is due to not only the horizontal force but also the shearing force. In most cases of double-sided shearing, the existence of the compensation effect was apparent.
