Friction and cutting characteristics of micro-textured diamond tools fabricated with femtosecond laser

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.

Automated summary

Experimental results show that micro-textured diamond tools significantly reduce cutting forces and friction coefficients, except for concentric circular texture. Additionally, the cutting performance of single-crystal diamond tools is effectively improved with the application of micro-textures.
