Die sinking electrical discharge machining (EDM) is widely used in making dies and molds of very hard, electrically conductive materials. In die-sinking EDM, as the servo feeds the tool into the workpiece, a relatively small gap between the electrode and workpiece hampers debris removal resulting in poor flushing conditions. The poor flushing leads to gap instability and harmful arcing resulting in inaccuracy and damage to both the workpiece and the tool. Many typical shapes (such as cylinder, cone, plane, involute, cycloid, and complex curved surfaces) can be machined using conjugate motion between the tool and the workpiece electrodes.
