Abstract
Metal matrix composites (MMCs) are widely employed in many industrial applications due to their excellent strength and wear characteristics. In order to overcome the challenges faced during machining MMCs, knowledge regarding machinability of MMCs is considered to be an asset. This paper contributes to this field through development of a novel micro-mechanical finite element model of the process. The developed model includes simulation of all phases of MMC workpiece and is employed for investigation of the effect of cutting speed on MMC machining process. Verification of the model predictions is achieved through comparison with the experimentally measured data. The presented model sheds light on the effect of cutting speed on the change in MMC behavior during machining and provides a significant contribution to the knowledge of MMC machining.
