| Abstract: | The state detection has significant effect on the machining stability,efficiency and accuracy of ultrasonic vibration electrical discharge milling.One of the gap voltage detection circuits was used to obtain the real-time waveform of the voltage between workpiece and tool electrode.The pulse voltage values from the voltage waveform were compared with three threshold voltages set by the computer,then open pulse,spark pulse,non-normal pulse could be identified.The effective method can be used to establish an ... |
