Abstract：Vibration cutting can produce many prominent cutting effects. There have been large numbers of literatures about vibration turning, vibration drilling and vibration grinding. However, until very recently, little research has been conducted in vibration milling, especially in high frequency vibration milling. Considering that less axial cutting depth is often adopted when milling small parts, neglecting the effect of helix angle, based on the FEM analysis software, a simulation model for the milling process of ultrasonic vibration assisted milling was established to research the cutting temperature. The simulation model predicts the temperature distribution of workpiece and cutting tool, and the temperature variation trend along with the cutting speed and machining time. The simulation results provide valuable references for researching on machining mechanism.The results show that using ultrasonic vibration assisted milling can greatly improve the temperature distribution at cutting area, drop the max temperature of tool, decrease the effects of various heating effect on cutting process.
