Composite is prepared by using stir casting technique. The influence of reinforcement ratios of 0, 4 and 8 wt. % of SiC on mechanical Properties is discussed. Machining of composite by using turning operation and its characteristics that influence the cutting force and surface roughness such as feed rate, depth of cut and cutting speed was studied. It was observed that increase of reinforcement element addition produced better mechanical properties. Experimental results revel that the cutting forces increases with increase in weight percentage and Flank wear and decreases with increase in the cutting speed. It was observed that the cutting speed, Flank wear and the feed rate at constant depth of cut affects the surface roughness during dry turning operation of cast MMCs. Taguchi L27 orthogonal array technique is considered with four factors i.e. Material, cutting speed, feed & artificially induced tool wear, each at 3 different levels, has been employed. The experimental results reveal that cutting speed is most influencing parameter when cutting force Fx is considered. Similarly when surface roughness is considered tool wear plays the most influencing factor.
