Effect of Addition of Nanoclay on Machinability of Al/Nanoclay Metal Matrix Composites

Abstract

In this study, machinability test was conducted on Al-Nanoclay metal matrix composites using lathe tool dynamometer. Composites were prepared with aluminium as the matrix and nanoclay particles with 2, 4, 6 percentage by weight as reinforcement. The effect of clay particles and machining parameters such as cutting speed, feed rate and depth of cut on tangential force and chip formation was studied. From the results it is observed that the tangential force applied by the tool on MMC, facilitate chip breaking and the generation of chips significantly depends on feed but almost independent of speed. These results reveal the roles of the nanoclay reinforcement particles on the machinability of MMCs and provide a useful guide for a better control of their machining processes
