Grindability Assessment of Metal Matrix Composites

In this paper, an experimental study on the grindability evaluation of Metal Matrix Composites is reported. To this purpose, experimental data obtained from tests carried out on a horizontal surface grinder have been employed. Investigations deal with the grinding forces and the degradation of the grinding wheel surface, acquired during the machining process and surface roughness of the workpiece material. The effects of grinding wheel abrasives, both conventional and superabrasives as well as the material characteristics, such as shape, orientation and content of the reinforcement and type of matrix, on the grinding wheel degradation and ground surface quality is analyzed by means of grindability indices.
