Abstract

Abstract: The surface machining mechanism of 3-D ultrasonic turning technology is studied by using the single-excitation 3-D ultrasonic assisted vibration device. Firstly， the simulation model suitable for 3-D ultrasonic cutting is designed by establishing the trajectory equation of the tool tip， and the simulation orthogonal experiment is designed. The influence of spindle speed， cutting depth and feed rate on surface morphology in 3-D ultrasonic turning process is studied by the multiple comparative analyses of variance. Then， the surface processing quality of 3-D ultrasonic turning and ordinary turning is compared through experiments， and the influence of processing parameters on 3-D ultrasonic turning and the optimal parameters are studied. The results show that compared with ordinary turning， 3-D ultrasonic turning can obtain better surface processing quality， and the influence of feed rate on surface roughness is the most significant. The optimal processing parameters are spindle speed 200r/min， cutting depth 0.12mm， and feed rate 0.18mm/r.
