is metalworking operation utilizing spark erosion for
very precise shaping of the metal workpiece. The workpiece (anode) and
electrical tool (electrode) are placed in a bath of dielectric fluid and
brought closer together until the voltage overcomes the insulating effect of
the fluid, causing a spark between the tool and workpiece. Consecutive
discharges produce a series of micro-craters on the workpiece until the
desired shape is achieved.
