The vibration ampli‐ tude of end face of the tool head is measured by selecting high‐speed laser displacement sensors, and then these date are transferred to computer by data acquisition card; based on LabVIEW de‐ velopment monitoring and controlling program, it can adjust tolerance comparator set point of laser displacement sensors on‐line by RS232C, and then change the inter‐electrode gap. Using the optimized ultrasonic compound electric machining system, selecting the reasonable processing parameters, the processing tests are conducted with cemented carbide. The results show that the ultrasound technology and compound electronic processing technology have technical advantages in machining hard and brittle difficult materials. Keywords Ultrasonic
