Four different micro textures were processed by 523 nm femtosecond laser on the diamond tool of NC lathe. Based on the transient double temperature model, the thermal erosion mechanism of femtosecond laser processing diamond rake face (100)was clarified. Results show that the residual stress of laser processed mesh texture is compressive stress, and the wide mesh texture and narrow mesh texture are -28 MPa±8 MPa and -43 MPa±9 MPa, respectively. Under dry friction conditions, the friction coefficients of all micro textured surfaces increase, and the worn surface has serious adhesive wear and poor wear morphology. However, the friction coefficient decreases significantly under lubrication condition, and the friction forms are mainly abrasive wear and sliding wear. The ability of grid texture to store lubricating oil is stronger than groove texture, and its anti-wear ability is the strongest.
