Three kinds of micro textures were processed on the rake face of cemented carbide tools on NC lathe by 532 nm femtosecond laser. Based on the interaction mechanism between laser and material, the formation mechanism of micro texture of cemented carbide processed by green laser is clarified, and its friction, wear and cutting properties under lubrication are tested. Results show that for all laser textured samples, all of the texture depth is about 18 μm±1.8 μm. The friction coefficient of cemented carbide on the original surface firstly increases and then decreases, with an average of 0.68, while the average friction coefficients of cemented carbide with groove, wide mesh and narrow mesh are 0.55, 0.45, 0.36, respectively. The cemented carbide with narrow mesh texture has the strongest wear resistance under lubrication. At the same time, the narrow mesh texture morphology of the rake face after cutting is the most complete, and the cutting depth is the largest, which is about 18.5 μm±0.9 μm.
