“…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].…”

“…Lal, Kumar [53] investigated the effect of parameters upon Al 7075/SiC/Al2O3 hybrid composite and found out that current has more effects upon kerf than the discharge time. 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.…”

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.

“…In the past, researchers had determined the optimum combination of process parameters for WEDM using techniques such as GA, SA, ABC, NSGA, and TLBO (Yusup et al 2012;Rao and Kalyankar 2014;Karunamoorthy 2006, 2008;Chiang and Chang 2006;Pradhan et al 2009;Satishkumar et al 2011;Sadeghi et al 2011;Mukherjee et al 2012;Rajyalakshmi and Ramaiah 2013;Garg et al 2014). Now, the NSTLBO algorithm is applied to solve the multiobjective optimization problem of WEDM.…”

Multiobjective optimization aspects of a traditional machining process namely surface grinding and five modern machining processes namely, wire-electro discharge machining process, micro-wire-electric discharge machining process, laser cutting process, electrochemical machining process, and electrochemical discharge machining process are presented in this chapter. A posteriori multiobjective optimization algorithm named as nondominated sorting teaching-learning-based optimization (NSTLBO) algorithm is proposed to solve the multiobjective optimization problems of the machining processes. A Pareto optimal set of solutions along with a Pareto front is presented for each of the considered machining processes.

“…Furthemore, mathematical models were also developed for the responses. Satishkumar et al (2011) investigated the effects of process parameters of WEDM on unreinforced Al6063 and also Al6063 reinforced with SiC 5%, 10%, 15% with a brass wire as an electrode. An L9 Taguchi orthogonal array was used and responses that were selected are MRR and SR.…”

In this paper an attempt has been made to study the effects of the process parameters of wire cut electrical discharge machining (WEDM) on Magnesium-Silicon Carbide MMC with 5% SiC in particulate form. For the analysis, six factors, namely pulse on time, pulse off time, spark gap voltage, peak current, dielectric flushing pressure and servo feed have been taken and a Taguchi L16 orthogonal array for two levels was used. Response surface methodology was also used to develop second-order models for material removal rate (MRR) and surface roughness (SR). From the analysis of variances, it has been observed that pulse on time and pulse off time were the most significant parameters among all those observed in predicting the MRR and SR, respectively.
