“…An increase of 10% in ceramic reinforcements may lead to an almost 12% reduction in machining efficiency [263]. However, SiC p /Al composites with high-SiC fractions can still be machined using WEDM [260,262,264]. Yang et al [265] reported the WEDM of a 65% (volume fraction) SiC/2024Al composite and proposed that the machining mechanism was a combination of melting of the Al matrix and decomposition of SiC particles.…”

Among the various types of metal matrix composites, SiC particle-reinforced aluminum matrix composites (SiC p /Al) are finding increasing applications in many industrial fields such as aerospace, automotive, and electronics. However, SiC p /Al composites are considered as difficult-to-cut materials due to the hard ceramic reinforcement, which causes severe machinability degradation by increasing cutting tool wear, cutting force, etc. To improve the machinability of SiC p /Al composites, many techniques including conventional and nonconventional machining processes have been employed. The purpose of this study is to evaluate the machining performance of SiC p /Al composites using conventional machining, i.e., turning, milling, drilling, and grinding, and using nonconventional machining, namely electrical discharge machining (EDM), powder mixed EDM, wire EDM, electrochemical machining, and newly developed high-efficiency machining technologies, e.g., blasting erosion arc machining. This research not only presents an overview of the machining aspects of SiC p /Al composites using various processing technologies but also establishes optimization parameters as reference of industry applications.

“…Moreover, composites have created a place in the field of hard to cut materials, in which, WEDM plays an important role. Various researchers have studied the effect of process parameters upon composites with the help of WEDM [51][52][53][54][55][56][57][58][59][60][61][62]. A semi-empirical model for MRR was proposed to study the thermo-physical properties of the work-piece [63].…”

“…They found that the cutting speed of the specified composites was obtained to be 3 and 6.5 times lower than that of the aluminium alloy. Again, Ebeid, Fahmy [56] initiated a mathematical formulation on AlSiCp composites and optimized the process parameters (machining voltage, volume fraction, pulse frequency, kerf size and workpiece height of SiC particles) with the WEDM characteristics (MRR, cutting speed and SR).…”

The growth in the new advanced materials that are harder till date have led to the improvement of technologies used to machine them. Nowadays, new materials have been developed to be used in different sectors where lighter and harder materials are in vast requirement. Moreover, materials machined with high precision machine tools have to provide the greatest surface finish such that it catches the pace with other competitive materials. Research has shown that the electro-discharge machining (EDM) is the only machine tool that has created history in machining hard materials. In the recent years, metal matrix composites (MMCs) have an increasing demand in the industries since they are hard materials to machine and a good finish is required in the aerospace, marine, aircraft, nuclear and other similar industries. Thus, EDM has gained fame in machining MMCs. With due course, the powder mixed electro-discharge machining (PMEDM) has created efficient EDM, with the use of powders in the dielectric. The dielectric mixed EDM has been used for efficient material removal rate (MRR). With the change in technologies, the sizes of powders that have to be added in the dielectric fluid go on decreasing. In this review, studies by numerous researchers on the MMCs that are machined with the use of PMEDM are mentioned. The powders used in the experimentation are of nano size. Furthermore, the optimization technique used by the researchers is discussed in the present study.

The use of unconventional machining techniques in shaping metal matrix composites (MMCs) has generated considerable interest as the manufacturing of complicated die contours. Metal matrix composites are advanced materials having high specific strength, good wear resistance, and high thermal expansion coefficient. Electrical discharge machining is a best process to make complicated shapes on the difficult to machine materials. The current paper presents a review of the research work done in electrical discharge machining (EDM) on MMCs. The review is categorized in to two stages namely wire cut EDM on composites and EDM on composites .This literature review helps to identify the suitable process parameters and their ranges in machining of composites.
