Abstract: By using a self-made MEDM-PMD equipment, the influencial factors to MEDM-PMD and surface properties machined by MEDM-PMD are investigated, and the corelation between surface quality and rules of powder property, workpiece materials, powder consistency and discharge parameters are also found out. Meanwhile, the suitable MEDM-PMD machining conditions are determined. By which, the forging die and die-casting mould are machined. It is revealed that the MEDM-PMD technique can improve the machined moulds qualty, reduce the workers load and shorten the machining cycle.
