Abstract
Method of effecting a supplemental bending operation on an initially bent workpiece which has been subjected to an initial bending operation at an initial bending position selected along the centerline of the workpiece, the method including a step of determining an actual relative position between the opposite ends of the initially bent workpiece, and determining, on the basis of the determined actual relative position, at least one of a supplemental bending position and a supplemental bending amount which are used for effecting the supplemental bending operation for reducing an error between the actual relative position and a nominal relative position between opposite ends of a product to be obtained by the supplemental bending operation, the supplemental bending position being different from the initial bending position, and a step of performing the supplemental bending operation at the determined supplemental bending position, so as to achieve the determined supplemental bending amount. Also disclosed is an apparatus for determining the supplemental bending position and amount.
