Abstract

A method of producing a workpiece by bending a panel in a bending press, in particular an edge bending press, with measures for compensating deformations of the edge bending press due to load. The measures involve detecting the displacement forces of drive means whilst the panel is being bent at a bending depth of the bending tools that is slightly shorter than a bending depth needed to produce a predefined bending angle. From the detected displacement forces, the bending deformation of the press beams corresponding to them are determined and the displacement force of the drive means is reduced, after which a compensating device is displaced in order to set a complementary camber in support surfaces for the bending tools or tool holders, and the panel is finally bent by displacing the press beam to the bending depth corresponding to the predefined bending angle.
