Electrical Discharge Machining (EDM) and Grinding (EDG .

A workpiece made of electrically conductive material and a shaped tool are immersed in a dielectric fluid. Rapid pulses of electricity pass through the tool (+ve electrode) and the negatively charged workpiece, leading to a spark discharge. Plasma forms and, along with the sparks, vaporises the workpiece material removing material 'chips', which are then flushed away by dielectric fluid.
