The work aims to study the effects of three different types of micro-textures on cutting performance of titanium alloy (TC4). Based on the finite element analysis software, the semicircular concave micro-texture, semicircular convex micro-texture and trapezoidal groove micro-texture were designed on the rake face of cemented carbide tool. The effects of micro-texture tool on radial thrust force, cutting temperature and friction force were studied by changing the micro-texture parameters, such as diameter or width, micro-texture spacing and covering length. Under the best micro-texture parameters, the radial thrust force of the semicircular concave micro-texture tool, semicircular convex micro-texture tool, and trapezoidal groove micro-texture tool was respectively reduced by 14.0%, 13.9%, and 18.6%. However, when the diameter of convex micro-texture was larger than 8 μm, the radial thrust force was greater than that of non-textured tool. The cutting temperature of three micro-texture tools was respectively reduced by 5.9%, 10.7% and 9.6%. The friction force of the three micro-texture tools was respectively reduced by 23.0%, 27.7% and 21.9%. Reasonable surface texture can improve the cutting performance of the tool. Trapezoidal groove micro-texture tool has the best effect of reducing radial thrust force. The semicircular convex micro-texture tool has the best effect of reducing cutting temperature and friction. With the increase of micro-texture diameter and spacing, the cutting performance of tools decreases firstly and then increases. And there are optimal texture parameters. In the range of the tool-chip contact length, the longer the textured covering length, the better the antifriction capability of micro-texture tool.
