Abstract: In order to improve the machining effect of 304 stainless steel, reduce the cutting force and prolong the tool life, a turning process combining micro-texture tools and three-dimensional ultrasonic vibration is proposed. Based on the orthogonal cutting model, the cutting force model for three-dimensional ultrasonic vibration turning of ordinary tools and micro-texture tools are established from the perspective of variable depth of cut and reduced contact area of micro-texture tools, using the friction reduction and interrupted cutting characteristics, respectively. The influence of various cutting parameters on the main cutting force was studied through the single-factor experiment of turning 304 stainless steel and comparing the tool wear. The optimal cutting parameter combination was studied through the orthogonal experiments. The results showed that compared with ordinary tools, the main cutting force of the micro-texture tool was reduced by 30%~40%; the wear degree was reduced by 11.50% on average; for reducing the cutting combined force, the best combination of cutting parameters is that the cutting depth is 0.1mm, the feed rate is 0.08mm/r, and the spindle speed is 250r/min.
