Review of machining metal matrix composites

Metal matrix composites (MMCs) are materials which have been widely used in the aerospace and automobile industries since the 1980s and have been classified as hard-to-machine materials. During the intervening years, only a limited amount of research has been conducted into the cutting action of MMCs. As with traditional materials, it is important to understand the wear mechanisms that contribute to tool wear which reduces tool life. The objective of this research is to evaluate the machinability characteristics for these hard-to-machine material MMCs. This review will also establish the optimum machining parameters vital to maximizing tool life whilst producing parts at the desired quantity and quality.
