• Chip forming process of ultrasonic vibration cutting is simulated by FEM as first. The change of the strain rate is larger, and cutting force acts on rake face and cutting temperature is slightly higher than the conventional cutting. Secondly, it is shown that the cutting force transfer from cutting point to the tool-work piece system, which has much lower natural frequency comparing with ultrasonic vibration, mainly depends on the ratio of net cutting time to vibration cycle in vibration cutting (tc/T). It is confirmed by the cutting experiment of resonated hone type work piece. The elastic deformation or recovery of several microns is also indicated both analytically and experimentally. The influence of this elastic behavior bocomes large relatively when tc/T is small.
