Abstract

In this paper, a geometric method is presented for predictive modelling of surface finish in grinding. The chip removal process by successive grains is modelled as a three dimensional Boolean operation, from which the surface roughness is predicted. A solid modeller is used to model an individual chip as a partial ellipsoid. The measured topography of the grinding wheel, together with kinematic relationship in surface grinding, is used to determine the geometrical characteristics of the proposed ellipsoid. The surface roughness predicted by the model is compared with experimental results. The results show good consistency between the model and the actual surface properties.
