  4. Abstract:
  5. Metal matrix composites (MMCs) have received considerable attention due to their excellent engineering properties. However, poor machinability has been the main deterrent to their substitution for metal parts. The hardness and abrasive nature of reinforcement phase causes rapid tool wear during machining which results in high machining costs. In this study, the effect of SiC particles (5, 15 & 20 percent) on tool wear in turning process is experimentally investigated. Continuous dry turning of Al/SiC particulate metal matrix composite produced by powder metallurgy and utilizing titanium carbide inserts has been achieved as the test method. The influence of machining parameters, e.g. cutting speed, feed rate and depth of cut on tool wear and cutting forces were investigated during the experiments. The results show that tool wear increases with increasing cutting speed, depth of cut and feed rate. The cutting speed and depth of cut are more dominant factors compared to feed rate on the tool wear. In addition, it is concluded that the flank wear increases with the increase of SiC percentage in the MMC
