An EDM machine with a plurality of separate electrodes selectively driven by the same actuator on the same head of the EDM machine is provided. Preferably, all of the electrodes are not used to cut the workpiece at the same time. Rather, the actuator has a drive mechanism, which is preferably servo-controlled, and each electrode is selectively engaged with the drive mechanism to advance and retract only the desired electrode relative to the workpiece. Either the workpiece or the EDM head is preferably manipulated using a CNC positioning system to accurately locate the desired electrode relative to the workpiece.
