Machinability Studies on Aluminium Matrix Hybrid Composites

Abstract

Aluminium metal matrix composites due to their excellent properties like high strength to weight ratio and high wear resistant are becoming new generation of materials useful for various engineering applications. A continuing problem with these composites is that they are difficult to machine. Machining of these composites depends on the relative content of the reinforcement and the matrix material as well as on its response to the machining process. Experimental investigations have been carried out on the machinability aspects of Aluminium hybrid composites reinforced with Graphite and Silicon Carbide particulates. Experiments have been carried out by Design of Experiments approach. Mathematical models which correlate the interactive and higher order influences of cutting parameters on the resultant force have been developed.
