“…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].…”

“…Satishkumar, Kanthababu [54] studied the machining characteristics of Al 6063/SiCp and developed regression equations to predict the output parameters. Rozenek, Kozak [55] carried out experiments to analyse the machining process parameters upon surface roughness of AlSi7Mg/SiC and AlSi7Mg/Al2O3 using WEDM. 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.…”

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.

“…Results show that the WEDM rates (mm/min) of both composites are equal. Rozenek et al (2001) investigated the effect of machining parameters (discharge current, pulse-on time, pulse-off time, voltage) on the machining feed rate and surface roughness during WEDM of AlSi7Mg/SiC and AlSi7Mg/Al 2 O 3 MMCs. Generally machining characteristic of metal matrix composites machined by WEDM is similar to those that occur in the base material (AlSi7Mg aluminium alloy).…”

In this study, the machinability of standard GGG40 nodular cast iron by WEDM using different parameters (machining voltage, current, wire speed, and pulse duration) was investigated. From the results, the increase in surface roughness and cutting rate clearly follows the trend indicated with increasing discharge energy as a result of an increase of current and pulseon time, because the increased discharge energy will produce larger and deeper discharge craters. Three zones were identified in rough regimes of machining for all samples: decarburized layer, heat affected layer, and bulk metal. High machining efficiency can be obtained when the proper electrical parameters are selected, but whether high energy or the low energy is used, a coarse surface is always obtained. The variation of surface roughness and cutting rate with machining parameters is mathematically modeled by using the regression analysis method.
