Abstract: The kinematics of the grinding process, characterised by the study of topography of grinding wheel surface and mechanism of material removal, taking into account conformity between grinding wheel and glass mould have been described for aspheric surface generation on glass moulds. The grit depth of cut analysis explains the influence of the geometry of the conformity between wheel and glass mould, which leads to some parametric relations in the grinding process. Some important parametric relations are derived form the geometrical model of aspheric surface generation with cup diamond grinding wheels. Image analysis technique was effectively used to observe the grinding wheel topography and texture of the ground aspheric surface. The experimental results are confirming the parametric relationship obtained by the geometric model for aspheric surface generation.
