| Abstract: | By using a self made MEDM PMD equipment, the influence factors to MEDM PMD and surface properties machined by MEDM PMD are deeply researched, and the influence rules of powder characteristics, workpiece materials, powder consistency and discharge parameters are also found out. At the same time, the suitable MEDM PMD machining conditions are determined. According to the determined machining conditions, the forging mould 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 time. |
