METHOD FOR CONTROL OF OPERATING CURRENT IN SPARK EROSION MACHINING Russian patent published in 1997 - IPC

Abstract RU 2074067 C1

FIELD: spark erosion machining. SUBSTANCE: method for control of operating current in spark erosion machining generated by pulse generator with the help of transistor power switches is effected by switching of power switches, respectively, from one kind of switching - simultaneous switching, simultaneous-alternating and simultaneous-alternating with cycle shift, alternating switching to some other kind of switching. EFFECT: higher efficiency. 1 dwg, 1 tbl
