Analysis of hydrodynamic forces in grinding

Post Date: 04 Dec 2008    Viewed: 10 Grinding of structural ceramics using fast wheel speeds and a copious fluid supply can cause significant hydrodynamic forces. The present investigation was undertaken to provide a fundamental description of the hydrodynamic behavior. Hydrodynamic forces were measured for various pre-set gap thicknesses between the wheel and the workpiece. The measured forces were analyzed by applying hydrodynamic theory to the converging inlet between the wheel and the workpiece. It was found that the inherent roughness of the grinding wheel surface could be taken into account by adding a correction factor to the gap thickness equal to the measured peak-to-valley roughness of the wheel surface.
