Investigations of Ultrasonic Vibration Turning

Ultrasonic vibration (UV) turning is a method with micro-scale high frequency vibration on the cutting tool to make the tool-workpiece interaction a periodically separation and the direction of the friction between tool and chip changed in each cycle of the ultrasonic vibration .The investigations show that the turning efficiency,the micro topography of machined surface can be improved and the ware of cutting tool, the deformation zone in a workpiece can be reduced by the application of the ultrasonic vibration machining. Finite element software simulation are performed on turning in this paper to clarify the advantages of applying tool ultrasonic vibration. The separation-contact process of ultrasonic vibration cutting and compare of ultrasonic vibration cutting force and normal cutting cutting force are studied.
