Abstract
Methods and apparatus are disclosed for the processing of a work piece by electrical discharge, the processing being carried out with at least two wire electrodes. In the process, the offset of both the positions of the at least two wire electrodes relative to one another are determined, which positions the wire electrodes occupy upon their clamping, because of their angles of contact on a corresponding wire guide and their different wire characteristics at the level of the work piece. Further, the positions for the wire electrodes during the processing of the work piece after a change from one wire electrode to the next one are connected on the basis of the offset determined between these wire electrodes.
