Technological models based on grinding wheel and workpiece characteristics in the grinding process of metal matrix composites

In this paper approaches to the modelling of grinding process of Metal Matrix Composites, based on empirical relationships, are proposed and discussed. To this purpose, experimental data obtained from tests carried out on a horizontal surface grinder have been employed. The simple relationships obtained could be utilised to predict how the grinding wheel type influences the grinding process and the machining quality of these non-traditional materials. The influence of shape, orientation and content of the reinforcement on the grindability of metal matrix composites is analysed. Investigations deal with grinding forces and degradation of the grinding wheel surface, acquired during the machining process and ground surface roughness. The effects of workpiece material composition on grinding wheel wear and ground surface quality is described considering grindability indices.
