Abstract
To achieve controlled stress grinding and controlled grinding of the depth of modificative layer, coupled analysis of grinding force and grinding heat is required. Therefore, this paper investigated grinding force and energy partition to lay a foundation for the coupled analysis. Firstly, a new grinding force model based on the analyses of grain trajectory and grain workpiece contact. In the modeling of grinding force, critical grain indention depths for plowing and cutting were calculated and the grinding force models of a single grain were established. This model can analyze the contributions of sliding, plowing, and cutting to total grinding forces. Secondly, an energy partition model was established based on the analyses of grain trajectory and grain workpiece contact. In the modeling of energy partition, the real contact area ratio and the grain contact radius were calculated. Finally, experiments were pursued to validate the grinding force model by comparing the experimental measurements to the theoretical results. Comparisons showed reasonable agreement quantitatively.
