The work aims to study the effect of surface micro-texture on cutting performance of cemented carbide cutting tools. Transverse, longitudinal and cross textures with different structural parameters were fabricated on the rake face of cemented carbide cutting tools by the micro-grinding method. The effect of surface micro-texture on cutting temperature and tool wear of cemented carbide cutting tools was studied by cutting experiment of AL6061 and finite element cutting simulation. The results showed that surface micro-texture with regular geometric shape and good surface quality could be fabricated by the micro-grinding method with V-shaped diamond grinding wheel. Compared with non-textured tool, the cutting temperature and high temperature area of micro-textured tool were significantly reduced, and the transverse textured tool had the most significant cooling effect. The cutting temperature of micro-textured tool increased as the groove spacing increased. The cutting temperature was the lowest when the groove spacing was 150 μm. The surface micro-texture could reduce the adhesive wear on tool rake face effectively. The transverse textured tool had the best anti-friction and anti-adhesion effect, and smaller groove spacing was more beneficial to reduce the adhesive wear of cutting tools. The anti-adhesion effect of surface micro-texture was more obvious as the cutting speed increased. when the cutting speed was 150 m/min, the chip adhesion area of transverse textured tool with 150 μm groove spacing was the smallest. Among the transverse, longitudinal and cross textured tools, the transverse textured tool with 150 μm groove spacing has the best cutting performance, which means that the cooling effect and anti-adhesion performance are the most significant.
