Patent number: 8573019Abstract: A method produces a bent part by two- or three-dimensional bending of an elongate workpiece, in particular a wire or tube, in a bending process wherein at least one portion of the workpiece is moved into an initial position in the region of engagement of a bending tool by one or more feed operations by the coordinated activation of the movements of driven machine axes of a bending machine numerically controlled by a control device and is formed by bending in at least one bending operation with the aid of a bending tool. The movements of the driven machine axes are generated according to a movement profile predeterminable by the control device of the bending machine and include at least one oscillation-relevant movement leading to an oscillation of the free end portion of the bent part. During an oscillation-relevant movement, a compensating movement, reducing the generation of oscillation and/or damping the oscillation, a machine axis is generated in at least one compensation time interval.Type: GrantFiled: October 8, 2010Date of Patent: November 5, 2013Assignee: WAFIOS AGInventors: Werner Steinhilber, Stefan Fries, Anton Schoenle, Matthias Groeninger
