Simulation and experimental research on grinding force and grinding surface quality of TiC-coated micro-grinding tools

Simulation and grinding experiments on soda-lime glass were performed in this paper. The influence of grinding parameters on the grinding force, surface roughness, and morphology of soda-lime glass after processing was studied in this paper. The change in grinding force, processed surface morphology, and surface roughness after grinding of different coated micro-grinding tools was discussed. Simulation results and experimental results have the same trend. The conclusion shows that as the grinding speed increases, the grinding depth and feed speed decrease, the grinding force decreases, the machined surface roughness value decreases, the surface morphology is smoother, and the surface quality is better. Under different cooling conditions, the machined surface roughness value of wet grinding is lower, and the surface quality is better. The surface quality of diamond-coated micro-grinding tools is better, by comparing CBN-coated micro-grinding tools and diamond-coated micro-grinding tools of the same particle size, and it is more suitable for grinding hard and brittleness materials such as glass. The research results provide a theoretical reference and experimental basis for reducing the grinding force of coated micro-grinding tools and improving the quality and processing performance of the machined surface.
