Electric discharge machining die sinking device

摘要

An electric discharge machine die sinking device includes a tank for holding a fluid, and at least one electrode in the tank having a shape for imparting to a first portion of a workpiece. A workpiece holder positions the workpiece at least partially immersed in the fluid and alternately moves the workpiece between an inoperable position and a first operable position of the first electrode at which electric discharge machining occurs on the first portion. A pulse generator creates an electric discharge between the first portion and the first electrode to remove material from the first portion in response to the workpiece being in the first operable position. Movement of the workpiece from the electrode flushes particle containing fluid away from the workpiece and the electrode. A segmented electrode includes a separate pulse generator for each segment may also be employed.
