Polishing of polycrystalline diamond by the technique of dynamic friction—Part 5: Quantitative analysis of material removal

This investigation aims to develop a quantitative model to estimate the material removal of polycrystalline diamond composites (PCDCs) by dynamic friction polishing. The model accounts for the contributions from the constitutive characteristics and thermal properties of the materials and the key polishing parameters. It was found that the material removal was dominated by six dimensionless variable groups involving chemical reaction, diffusion and mechanical wear. A comparison with the experimental measurement showed that the model predicts quantitatively and can be used conveniently for process planning and equipment design.
