Abstract

In this work a model is presented that quantifies this abrasive tool wear. The foundation of the model is on the level of surface roughness. The surface micro-geometry of both the abrasive surface and the wearing tool are measured using an interferometer. Based on this data, the surface geometry in each of the micro-contacts is represented using a so-called asperity. Such an asperity has either a conical or a paraboloidal shape and is fitted through the surface geometry. The behaviour of an asperity, or summit, in contact with a deforming counter surface is described in an elastic- elastoplasticplastic contact model. Using experiments, the abrasive wear of modelsummits is studied. These results are embedded in an empirical model. The summation over all the summits in contact finally results in the abrasive wear behaviour in the contact of rough surfaces.
