Abstract :The shearing resistance. backing of the sheared product. fraction of the sheared face and the dimensional error were investigated by varying the chamfering profile and clearance, The following are concluded. 1) The shearing resistance is dependent rermarkably on the shape of the edge tip and the clearance. When the punch flank is chamfered largely for certain clearance, the shearing resistance is increased a little. 2) Also the backing of the blanked product is dependent on the shape of the edge tip and the clearance. When the edge tip is chamfered, the magnitude of the backing is increased. 3) The fraction of the sheared area of the cut cross section is hardly influenced by the shape of the edge tip. 4) The dimensional error of the blanked product varies with the plate thickness of the work. When the work is thin, the effect of the edge tip shape becomes remarkable. When the work is thick, the effect is reduced.
