The present work has been undertaken to study the tool wear behavior of poly crystalline diamond (PCD) inserts during the machining of Al-SiC – MMC; Al-Si alloy containing 15%wt of SiC was used for machining and PCD inserts of three different grades were used as cutting tools. The main aim of this paper is to explore the feasibility of machining conditions by setting the spindle speed, depth of cut and thereby determining the cutting force, surface roughness, power consumed, material removal rate and tool wear. The worn surface of the insert was examined by Scanning electron microscope (SEM). The influence of cut was examined for the PCD inserts.
