  • Wire electrical discharge machine and endface position determining method
    Patent number: 11458554
    Abstract: A wire electrical discharge machine determines the position of an endface of a workpiece by relatively moving a wire electrode toward the workpiece. The wire electrical discharge machine includes: a voltage application control unit configured to continuously apply voltage pulses between the wire electrode and the workpiece; a voltage detection unit configured to detect a voltage between the wire electrode and the workpiece; a pulse occurrence ratio calculation unit configured to calculate a pulse occurrence ratio that is a ratio of the number of the voltage pulses detected by the voltage detection unit to the number of the voltage pulses applied per a predetermined time by the voltage application control unit; and an endface position determination unit configured to determine the position of the endface of the workpiece based on the pulse occurrence ratio.
