Article Preview

In ultrasonic vibration assisted grinding (UAG) along the axial direction, the machining process of an abrasive grit is introduced in this paper. During the internal UAG, the critical speed is determined by the amplitude and frequency of ultrasonic vibration. During the surface UAG, the cutting model of an abrasive grit is established and the cutting trace length of an abrasive grit and the grinding force making chips deformation is analyzed in theory. The analysis results show that the cutting trace length is longer by introducing ultrasonic vibration along the axial direction; the grinding force is decreased, the higher vibration amplitude and frequency is helpful to the decrease of the grinding force and the higher grinding wheel speed weakens the contributiveness of ultrasonic vibration to the decrease of the grinding force.
