Springback is an attempt to recapture the original material after bending. Since all materials have limitations Modulus of elasticity
, control the rebound is relying on the bending radius and thickness of the material. The uniformity of thickness and an increase in the radius of curvature. Cause a rebound increase. In order to get the desired shape Workpiece may be bent over like that. The example below Shows Bending down beyond the desired shape.
