Abstract:

The low machining efficiency of separated ultrasonic elliptical vibration cutting limits its application and development. To promote the application of this technology, the paper presents a study of the mechanism of unseparated ultrasonic elliptical vibration cutting which reduces cutting force based on an analysis of the cutting process. It also analyze the effect of velocity coefficient and cutting depth direction amplitude on cutting force, reveals the main causes for the reduced cutting force in unseparated ultrasonic elliptical vibration cutting are the inverter area and dynamic rake angle, and also give the failure judgment formula of velocity coefficient for reducing the cutting force. The experiment proves that unseparated ultrasonic elliptical vibration cutting reduces the cutting force effectively and improves the process stability. This is significant for the ultrasonic elliptical vibration cutting to extend its application field.

Key words: unseparatedness, cutting force, vibration, inverter area, dynamic rake angle
