Ultrasonic elliptical vibration cutting

Abstract A new cutting method named ultrasonic elliptical vibration cutting is proposed and applied to cutting of metals by utilizing a new vibrator to vibrate the cutting tool elliptically at ultrasonic frequency. It is confirmed experimentally that the cutting performance, in terms of the cutting force and the chip thickness, is improved significantly by applying the elliptical vibration to the cutting tool. The experimental results prove that the method can be applied to practical ultraprecision cutting of metals.
