Abstract
In this paper an attempt has been made to fabricate hybrid aluminum metal matrix composite with a composition of 7wt% Silicon carbide and 3wt% Alumina using stir casting method. Morphology of the composite and reinforced particle distribution were studied by optical microscopy. The fabricated cast composites were carefully machined. The influence of machining parameters like cutting speed (s), feed rate (f) and depth of cut (d) on surface roughness (Ra) and cutting force (F) was investigated during experimentation. The optimal machining parameters have been found by Analysis of Variation (ANOVA). Results shows that when cutting speed increases surface roughness value decreases. Also it shows cutting force is directly proportional to cutting speed. Tool wear study has been made to find out tool wear during machining. It is concluded that tool wear is directly proportional to depth of cut. © Research India Publications.
