ABSTRACT:
A method of operating a bending press, in particular an edging press, and a bending press for carrying out this method. For each drive of a drive arrangement, the actual pressing force is detected for the displaceable press beam during a bending process for the workpiece and a relative position of the pressing tool or tools by reference to the longitudinal extension of the press beams is determined on the basis of a force ratio. Different displacement paths of the drives and the displaceable press beam at the respective force-application point of the drive are then determined in an evaluation and/or computer unit, which is provided with a data memory for production and machine data, and corresponding control signals for the drive system are generated in the control unit and actuator elements of the drives are displaced by the displacement paths determined for each drive.
