ABSTRACT:
Process and apparatus for cutting by electrical discharge machining cavities and slots in an electrode workpiece by means of an electrode tool, the electrodes being displaced one relative to the other in translation along a predetermined path. The translation motion is controlled such as to maintain predetermined machining conditions in the machining zone between the electrodes, and for additionally displacing the electrodes relative to each other in a direction different from the direction of the cutting path. The additional relative displacement of the electrode may be linear, non-linear, slanted or curvilinear.
