Abstract

PURPOSE:To improve the final shape accuracy by detecting the angle of the change in the feeding direction of work to be commanded and the radius of an arc and changing the discharge condition in accordance with this detection signal. CONSTITUTION:Discharge voltage is applied between the wire electrode 1 and the worked piece 3 with the working power supply 5. The X-Y cross table 6 on which the worked piece 3 is loaded is driven by the X-axis motor 7a and the Y-axis motor 7b. The move command signals to the wire electrode 1 of the worked piece 3, i.e. the signals corresponding to the program traces 2 are given to the drive controller 8 which gives drive signals to these motors, through the N/C tape 9 on which the program traces 2 are writtern, the tape reader 10 which reads them, and the numerical controller 11. The signals of the program traces 2 are concurrently sent to an arithmetic unit 12 to determine any angle variation in the feeding direction of work, and entered into the radius of an arc operation device 13. These signals permit the discharge condition of the working power supply 5 to be changed.
