“…As a result of this instability, recast layer is formed due to melting and vaporization that makes the surface of work piece uneven and rough. Chiang [110] emphasized that current has a direct effect on TWR whereas pulse-on time has an inverse effect. TWR can be reduced by using rotary tube electrode in EDM and electrode having higher electric, thermal and wear resistance along with easy manufacturability.…”

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.

“…Nanoindentation and SEM results show the heat-affected zone has more compact microstructure and higher hardness and modulus of elasticity than that of the bulk material [6]. The recast layer with craters, cracks, and bubbles deteriorates the surface properties and reduced the wear and fatigue life of EDM mechanical parts [2][3][4][5][6]. In this study, the abrasive microblasting process was applied to remove the damaged surface layers and improve the surface integrity of WC-Co parts machined by wire EDM.…”

“…11,28,58,59 Residual stresses Amongst the various defects observed during EDM, residual stress, which is generated due to uneven solidification of molten metal, is the most significant defect that may lead to failure, especially under tensile loading or may also cause corrosion. 60,61 When the induced residual stresses exceeds the ultimate strength of material the failure appears in the form of cracks. 62 A sudden collapse of bridges and heavy structures in March 1938 in Belgium attracted attention of designers toward residual stress, which is induced during processing.…”

Processability of metal matrix composite depends upon the appropriately chosen elements, their properties, distributions and interface between them. The ductile property of matrix embedded with ceramics reinforced particles serves to reduce the coefficient of thermal expansion and increase strength and modulus. High tool cost in traditional machining process results in limiting the application of these materials in advance technologies; hence, electric discharge machining process is a widely accepted machining option for geometrically complex-shaped components. This article presents the basic selection of elements and fabrication methods of metal matrix composites and further reviews the research work carried in the field of electric discharge machining to explore ways to improve the efficiency of the machining process. Finally, the research works carried out to measure the residual stress are also addressed, followed by concluding remarks and future scopes.
