Abstract

Aluminium-Silicon Carbide composites are rapidly gaining importance because of their potential to produce components that features low density while maintaining high stiffness, strength, thermal stability, improved fatigue properties and wear resistance. The presence of hard SiC particles in these materials presents considerable difficulties when machining these materials resulting in rapid tool wear. 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. In this context an attempt is made here to study the influence of graphite particulates added to Al-SiC composites on tool wear. Experimental investigations have been carried out on the machinability aspects of Aluminium hybrid composites reinforced with Graphite and Silicon Carbide particulates. Machinability is expressed in terms of average flank wear caused during machining. Turning tests were carried out on Aluminium-Silicon Carbide-Graphite composite specimens to determine the tool wear on carbide inserts. It is found that the presence of graphite particulates reduces the average flank wear.

Keywords
