Electrical Discharge Machining (EDM)

Electrical discharge machining is a machining method that discharges electrical sparks between two metal electrodes placed opposite each other in a solution such as water or oil. The heat generated melts or vaporizes the metal without contact.

EDM uses wire-cut EDM machines and die-sinking EDM machines. Wire-cut EDM machines use a very thin copper wire as the electrode to machine the workpiece. Die-sinking EDM involves creating an electrode with a shape that is the inverse (mirror image) of the desired shape to be machined, and then using the electrode profile to machine (transfer the profile) into the workpiece, similar to engraving.
