Abstract (en)

The method involves moving a wok-piece along an axis (58) and simultaneously rotating the work-piece around another axis (64), where the axis (64) incorporates a finite angle with the axis (58). The work-piece is moved along a third axis (26), where the axis (26) incorporates the finite angle with the axis (58) and the axis (64), and the work-piece is moved in fast oscillating movement along the axis (58) in a direction tangential to the processing of the work-piece. Independent claims are also included for the following: (1) a machine tool for machining a work-piece (2) a programming system for evaluating programming parameters.
