微织构已初步应用于金属、陶瓷和硬质合金刀具的减磨。然而，目前还不清楚哪些微纹理将有效地减少单晶金刚石工具的磨损。本文验证了显微织构对单晶金刚石工具摩擦和切削性能的影响。利用飞秒激光在金刚石刀具前刀面上生成了直槽阵列、同心圆织构、环序织构和网状织构4种微织构。实验结果表明，除同心圆织构外，微织构金刚石刀具的切削力和摩擦系数均显著降低。同时，单晶金刚石刀具的切削性能也得到了有效的改善。
Micro-textures have been preliminarily applied to reduce the wear of metallic, ceramic, and carbide tools. However, it is still unclear which micro-textures will be effective in reducing the wears of single-crystal diamond tools. In this paper, the effectivity of micro-textures on the friction and cutting characteristics of single-crystal diamond tools were verified. Four types of micro-textures including straight grooves array, concentric circular texture, ring sequence, and mesh texture were generated on the rake face of the diamond tools with the femtosecond laser. Experimental results showed that the cutting forces and friction coefficients of the micro textured diamond tools were greatly decreased except for concentric circular texture. Meanwhile, the cutting performances of the single-crystal diamond tools were effectively improved.
