METHOD OF ELECTROCHEMICAL DIMENSIONAL MACHINING Russian patent published in 1995 - IPC

Abstract RU 2038928 C1

FIELD: mechanical engineering. SUBSTANCE: during machining, present magnitude of pulse voltage is checked; specially separating voltage surges at electrode approach and separation sections and equality of surges is maintained by delaying or leading supply of pulse relative to moment of minimum electrode gap. Rate of feed is being increased till third local voltage extremum is formed in center of pulse after which rate of feed is maintained at such level when relationship given in the description is satisfied. EFFECT: enhanced efficiency. 2 dwg
