Abstract: To further improve the machining effect of 304 stainless steel, a theoretical model of friction reduction characteristics was established by combining the analysis of tribological dynamic loads with 3D ultrasonic vibration assisted turning. The friction reduction effect was further improved by incorporating the micro-textured tool into the model, and was verified by the experiments on the combined cutting forces of spindle speed, feed, and cutting depth. The theoretical model of surface profile formation was established by considering the relative vibration of machine tool, and the effects of cutting parameters on surface roughness were investigated by the single-factor experiments, which showed that the surface roughness gradually increased with the increase of cutting depth, spindle speed and feed rate, the surface roughness gradually increases.

Key words: three-dimensional ultrasonic vibration; friction reduction characteristics; surface roughness; micro-texture tool; cutting force
