In this paper, we discuss the clearance compensation effect in precision shearing. This effect is based on the hypothesis that unbalanced clearance is automatically compensated by the bending of a punch when shearing is performed using a long and thin punch. We also discuss the compensation mechanism through various experiments and an elastic-plastic finite element method. When the clearances on the right and left sides differ, the shearing and horizontal forces acting on both punch sides also differ slightly. These forces result in moments that bend the punch. The clearance compensation effect depends on the magnitude and direction of these moments. In other words, 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.
