| 摘要 |
The invention relates to a method for material-removing machining by means of a machine tool (1), in particular a punching or combined punching/laser machine, of a workpiece (2) clamped in a workpiece holder (3), wherein the workpiece holder (3) is movably mounted and driven (7) by electric motor in order to perform a movement sequence of target workpiece movements necessary for machining the workpiece, the method comprising the following steps: a) defining initial control parameters that are independent of workpiece dimensions for controlling the electromotive drive (7); b) performing one of the target workpiece movements on the basis of the control parameters; c) determining an approximate value of the current workpiece dimensions; d) adapting the control parameters to the approximate value of the workpiece dimensions; and e) repeatedly performing method steps b) to d), until the movement sequence is finished. |
