Abstract: According to the properties of the CNC precision internal grinding, the Human-machine interface system for the CNC based on industrial-grade touch device is proposed in this paper. Based on analyzing the human-machine interface system on the whole, each module is described in detail. The whole human-machine interface system is friendly, convenient and flexible, which meet the function requirements of embedded CNC precision internal grinder.

Abstract: A new ultrasonic elliptic vibrator design method was proposed, the ultrasonic elliptic vibration was achieved by the structural curve of the longitudinal and torsional vibrations. The model, harmonic and transient analyses of the new longitudinal-torsional composite ultrasonic elliptical vibrator were performed by using the software ANSYS, the prototype of the new vibrator was tested by using impedance analyzer and PSV-400 laser Doppler vibrometer, the correctness of the finite element simulation results and the feasibility of the new longitudinal-torsional composite ultrasonic elliptical vibrator design methods were verified.

Abstract: Based on designing problems of the vibrator composed by the transducer, horn and tool in the ultrasonic vibration internal grinding (UVG) system, a new whole vibrator design method were proposed. The model and harmonic analyses of the new whole vibrator were performed by FEM, the prototype of the new whole vibrator was tested by using impedance analyzer and PSV-400 laser Doppler vibrometer, the correctness of the finite element simulation results and the feasibility of the new whole vibrator design methods were verified.
