Metal matrix composites (MMC) are the combination of base metal matrix and reinforcing materials like SiC, Al2O3, etc. The present research is focused on the machinability studies of Al 6061 reinforced with 10% wtof Al2O3 particles using multi layered coated carbide inserts. Fabricated samples by stir casting route were turned by the most variable factors, cutting speed, depth of cutand by a constant feed rate of 0.206 mm/rev. Surface roughness and tool wear are considered asoutput. Experiments are conducted by varying the cutting speed while keeping feed rate and depth of cut as constant. After the optimum cutting speed was determined, the depth of cut is varied by keeping the cutting speedand feed rateas constant.Based on the optimum cutting speed (150 m/min), depth of cut (1.2 mm) and feed rate (0.206 mm/rev), a long run test was carried out to find out the tool life and surface finish. But due to the softness nature built up edge formation is obtained. At the optimal parametric combination, the built up edge obtained is less than 2 mm for a machining time of 425 s
