摘要： An electric discharge machine includes a machining power supply for applying a voltage to a machining gap between a machining electrode and its opposite workpiece and detecting a contact between the machining electrode and the workpiece. The machining power supply includes a first power supply circuit whose output voltage is equal to or less than an arc voltage, a second power supply circuit for supplying a pulse current to the machining gap, and a control unit. When the first power supply circuit detects a contact between the machining electrode and the workpiece, the control unit operates to supply a pulse current from the second power supply circuit to the machining gap while the machining electrode and the workpiece are in contact with each other.

摘要： In a torque motor driving device for wire cut electrical discharge machines, a voltage waveform rectified by a full-wave rectifying circuit, not using a high-capacitance electrolytic capacitor, is applied as an AC voltage to a single-phase torque motor by a bridge circuit including semiconductor switches. A PWM signal whose duty is adjusted so that the current flowing through the torque motor matches an instructed value is generated and the generated PWM signal is used for the operation of the bridge circuit.

摘要： A voltage is applied to a machining gap between a wire electrode and a workpiece for a period of one microsecond or less with a quiescent time longer than the duration of voltage application between each two adjacent cycles of voltage application provided, and the number of duty cycles and a machining-gap voltage are detected. An open-circuit state in which electric discharge does not occur after the voltage is applied is identified by the detected machining-gap voltage, and the number of open-circuits is counted. An average machining-gap voltage is obtained based on the numbers of duty cycles and open-circuits and the supply voltage or an average voltage for each duty cycle.

摘要： The number of electric discharge pulses is detected every given period. A deviation between the detected number and a target number of electric discharge pulses is obtained. Based on the obtained deviation, a correction value for the correction of a machining path in a direction normal to the machining path is calculated, whereby a corrected path is obtained. A wire electrode is moved relatively to a workpiece along the corrected path.
