Abstract

PURPOSE:To set the optimum distance between fulcrums in proportion to the thickness of a work automatically and with high accuracy by a method wherein the optimum distance between fulcrums is computed by a numerical control unit in proportion to the thickness of the work and the distance between the fulcrums is set by a driving device. CONSTITUTION:A holder 70 is fixed in a unitary body to a slider 44 on which an upper fulcrum 34 and an upper feeder plate 26 are fixed. A contactor 72 being supported by this 70 moves in a vertical direction together with the displacement of the slider 44 and a contact position data in the vertical direction is inputted to a numerical control unit 54 when the contactor comes in contact with the surface of a work 18. This numerical control unit 54 calculates backward the thickness of the work 18 in the electric discharge machining position, drives a Z-axis servomotor, moves the upper fulcrum 34 of the upper and lower fulcrums 34, 36 of a wire electrode 20 and sets a distance between these two fulcrums 34, 36 to the optimum in order to conduct precise electric discharge machining of the work 18.
