Servo-controlled high-power electric spark machine produces repeated discharges between tool electrode and workpiece to cause erosion of metal to desired shape. Power source is 4.5-KV three-phase rectifer providing peak discharge current of 4,500 amp at pulse repetition rate of 2,880 pps. Rotary gap is used for pulse switching.-E. M. Williams and C. P.
