The effects of grit properties and dressing on grinding mechanics and wheel performance: Analytical assessment framework

Abstract

This paper introduces an analytical assessment framework for evaluating grinding wheel performance derived from the model of cutting and sliding grinding force components. Four new parameters are proposed based on wheel topography. These parameters are normalized through the aggressiveness number, which circumvents the influences of grinding geometry and kinematics. The framework is validated through experiments with different wheel topographies obtained by changing dressing conditions and grit properties (toughness, thermal stability and shape). The framework and experiments quantify how wheel wear flat area influences the sliding component and how grit protrusion influences the intrinsic specific grinding energy. This framework provides a rational basis for evaluating grinding-wheel performance and abrasive-grit selection.
