Abstract
A method for controlling the bending of a metal sheet includes the steps of: establishing a relational database on a relationship among material parameters, forming angles, amounts of springback, and amounts of press of an upper die; blanking and reverse-engineering a material parameter of a metal sheet to be processed; comparing the material parameters in the relational database with the material parameter of the metal sheet to be processed which is obtained by the reverse-engineering; and performing an bending operation.
