Intrinsically smart, metal matrix composites (MMCs) are lightweight and highperformance materials having ever expanding industrial applications. The structural and the functional properties of these materials can be altered as per the industrial demands.The process technologies indulged in fabrication and machining of these materials attract the researchers and industrial community. Hybrid Electric discharge machining is a promising and the most reliable non-conventional machining process for MMCs. It exhibits higher competence for machining complex shapes with greater accuracy. This paper presents an up-to-date review of progress and benefits of different routes for fabrication and machining of composites. It reports certain practical analysis and research findings including various issues on fabrication and machining of MMCs. It is concluded that polycrystalline tools and diamond coated tools are best suitable for various conventional machining operations. High speed, small depth of cut and low feed rate are a key to better finish. In addition, hybrid EDM has proved to be an active research area in critical as well as non-conventional machining since last few years. This paper incorporates year wise research work done in fabrication, conventional machining, nonconventional machining and hybrid machining of MMCs. Conclusions and future scope are addressed in the last section of the paper.
