Abstract (en)
[origin: WO03072278A1] The invention relates to a method for reducing bending angle errors when bending a metal sheet in a bending press, comprised of a stationary lower tool (6) and a bending beam (4a, 4b), which is driven by linear axles (3) and provided with upper tools (8). The lower reversal point of the bending die is pre-calculated based on the pre-set specified value of the bending angle and on the force-path course measured during the bending process. The force-path course is measured by a position transducer (7) and a force transducer (8) and is processed inside the control unit (9).
