Die-sink electrical discharging machining is cutting into the workpiece by eroding the material around the “cutter” using electrical discharges (sparks). Material is removed from the workpiece by a series of rapidly recurring current discharges between the positive and negative sides of the machines platens while separated by a dielectric fluid (which is inherently non conductive) and subject to an electric voltage. Usually the upper platen is where the cutting tool or “electrode” is located an the table would hold the “workpiece”.

Wire EDM is process whereby a wire typically 0.015mm to 0.02mm in diameter is electrically charged at a very high voltage and used to cut precision shapes in prismatic components. The wire is passes from one spool to another and is guided by and an upper and lower guide as it cuts.
