Calculation prediction of grinding force from work material properties and grinding conditions

Abstract

Grinding force is an important parameter related to a grinder’s properties including spindle power, machining strain, and grinding heat. A calculation method using experimental values of specific grinding energy has been known previously. In this paper, we focused on the shear force of grinding chips and calculated predictions of their tangential and normal forces from the physical properties of workpiece materials and grinding conditions. In the results, the tendency and magnitude of the grinding force of an actual machine and the predicted results were generally consistent with respect to the workpiece material and depth of cut. We believe that this method allows calculation of the grinding force in advance for workpiece materials and grinding conditions, contributing to reduced burden during set-up for conditions without having prior experience.
