In order to solve the problems of large cutting force,high cutting temperature and serious tool wear in the process of titanium alloy cutting,scholars have tried to use micro texture tools to solve these problems in recent years.In this paper,the application of micro textured tools in titanium alloy cutting is reviewed.The cutting mechanism of micro textured tools in improving surface quality,reducing cutting force,tool wear,friction coefficient and cutting temperature is analyzed,and the problems in micro texture cutting titanium alloy are pointed out.
