ABSTRACT:
The target stroke amount calculation portion obtains an initial value of the target stroke amount of a punch according to bending information including workpiece condition of a workpiece to be bent, tool condition, target folding angle, and the like. The bending information setting portion sets the bending information in the workpiece bending simulation processing portion, in a specified form. The element breakdown calculation portion divides workpiece sectional image according to the bending information to a plurality of major portions and further divides these portions to detailed portions. The workpiece bending simulation processing portion virtually deforms the workpiece according to elastoplasticity finite element method corresponding to a virtual descent of the punch by the target stroke amount and obtains workpiece deformation image after a spring-back. The target stroke amount determining portion the folding angle of a deformation image with the target folding angle so as to determine whether or not both of them coincide with each other. If the folding angle of the deformation image does not coincide with the target folding angle, the stroke amount correcting portion determines a new target stroke amount and sets it in the workpiece bending simulation processing portion.
