Abstract: A design solution of machine tool control system and its hardware and software design were proposed for the requirement of high precision internal grinding. The ARM microprocessor was used as the system control center and the technical grade touch screen was used as the human machine interface. The feed motion of the X, Z 2-axis servo motor was controlled by the system to complete the grinding path, and the machine tool switching signal was controlled by the Soft PLC Technology. The whole system has the advantage of stable, high performance and user friendly, meeting the requirement of high precision grinding.

Abstract: Based on the FEM, the properties of the vibrator and the shaft in new ultrasonic vibration internal grinding system were studied in this paper. The design method of new ultrasonic vibration internal grinding (UVG) system by using rotary non-contact transmission device was proposed according to the influence of the sleeve length and thickness to ultrasonic vibration shaft. Experiments about the vibrator，the shaft and the ultrasonic vibration internal grinding system were studied by using PSV-400 Laser scanning vibrometer, and the consistency between the new ultrasonic vibration internal grinding prototype and theoretical design was confirmed.
