Abstract

In ultrasonic vibration the cutting edge of a tool is vibrated in the principal or cutting direction, generally at a constant ultrasonic frequency. The main characteristic of this cutting method is its intermittent nature involving repeated cutting and pausing. In this paper, ultrasonic elliptical vibration cutting is used to assist micro-groove turning of cylindrical surfaces. The elliptical locus during the cutting process is generated by a newly designed 2D resonant ultrasonic vibrator. A series of experiments were performed to verify the effects of the ultrasonic elliptical vibrations. The generated cutting forces and burr formation were compared for the ordinary and the elliptical vibration-assisted cases. Comparison results show the effectiveness of the elliptical vibration cutting method in reducing cutting forces and alleviating burr formation.
