Abstract
A press forming machines includes displacement measuring means for measuring a displacement between a slide plate and a reference plate. Control means measures a positional displacement of each of the driving sources by using the displacement measuring means in each of a plurality of operating steps during the molding operation, detects a desired displacement position of the entire slide plate, extracts control data including a correction amount to maintain the entire slide plate at the desired displacement position, the correction amount corresponding to a change in load on each of the driving sources, stores the control data in the memory, supplies the control data to the driving sources, and separately drives the driving sources. Since an actual molding operation can be performed using control data generated in a trial molding operation, the cycle time of the actual molding can be shortened.
