“…Senthilkumar T.S. [21] investigated the effect of particle content on the surface topography in EDM of aluminum hybrid composites with a particle content of 5-8%. It was found that, with an increase in particle content, MRR decreased, while the surface hardness and the diameter of the craters increased.…”

With the properties of high specific strength, small thermal expansion and good abrasive resistance, the particle-reinforced aluminum matrix composite is widely used in the fields of aerospace, automobile and electronic communications, etc. However, the cutting performance of the particle-reinforced aluminum matrix composite is very poor due to severe tool wear and low machining efficiency. Wire electrical discharge machining has been proven to be a good machining method for conductive material with any hardness. Even so, the high-volume SiCp/Al content composite is still a difficult-to-machine material in wire electrical discharge machining due to the influence of insulative the SiC particle. The goal of this paper is to analyze the machining characteristics and find the optimal process parameters for the high-volume content (65 vol.%) SiCp/Al composite in wire electrical discharge machining. Experimental results show that the material removal method of the SiCp/Al composite includes sublimating, decomposing and particle shedding. The material removal rate is found to increase with the increasing pulse-on time, first increasing and then decreasing with the increasing pulse-off time, servo voltage, wire feed and wire tension. Pulse-on time and servo voltage are the dominant factors for surface roughness. In addition, the multi-objective optimization method of the nondominated neighbor immune algorithm is presented to optimize the process parameters for a fast material removal rate and low surface roughness. The optimized process parameters can increase the material removal rate by 34% and reduce the surface roughness by 6%. Furthermore, the effectiveness of the Pareto optimal solution is proven by the verified experiment.

“…It was observed that pulse on time had the most significant effect on surface roughness. Senthilkumar and Muralikannan 165 employed an L27 Orthogonal array to design an experiment and studied the effect of powder addition and process parameters on TWR and MRR. An augmentation in MRR was observed with an increase in pulse on time, whereas a diminishing MRR was observed with enhancement in powder concentration.…”

Electrical discharge machining (EDM) is an exigent focus of interest for researchers since its inception. EDM has a wide range of applications due to its non-contact machining process based on the spark erosion method. EDM is a non-conventional machining process with high potential in the recent industrial era. Due to the few limitations of EDM, many hybrid techniques are evolved in recent years. The present review paper elucidates the in-depth mechanism of the material removal process in EDM. Hybrid EDM processes are also reviewed with special attention on powder mixed electrical discharge machining (PMEDM). A detailed comparison between the EDM and PMEDM is presented with a meticulous portrayal of the advancement and evolution of PMEDM. The emphasis is given on significant performance parameters, namely tool wear rate, material removal rate and surface roughness, besides other parameters. In addition, the study also includes different modelling, optimization, and surface analysis techniques on EDM. The paper concludes with the future scope of PMEDM in the fields of manufacturing along with its applications.

“…Dissemination of grains is acknowledged to be intra-granular, in which the maximum particles locate inside the grains. The uniform distribution is commensurate with the efficient and timely stirring action during the stir casting process [22]. The crater's size is less with B 4 C particles this could be because of the creation of a boron oxide (B 2 O 3 ) layer on the B 4 C ceramic, because of liquid-to-liquid reaction leading to an expansion in the wettability, which is observable at a specialized high temperature [23].…”

This unit deals with the selection and fabrication of HMMC (Al6063-10SiC-5B4C-Mg) constituents by extensive biography review and satisfactory fabrication design. Researchers have promoted an extensive collection of Al6063 composites employing organic and inorganic reinforcements. The fundamental purpose of the broken-up stages is to constrain the metal matrix in a relevant capacity to strengthen the properties of the base materials. In the case of Al6063, the reinforcement weighty subject matter in the composite varies from 5 wt.% to 30 wt.%. Diverse classes of reinforcements had sought to integrate and operate in the composite formulation as hybrid reinforcements. This chapter further discusses the comprehensive development stages of 84% wt of Al 6063, 10% wt of SiC, 5% wt of B4C with 1% wt of Mg hybrid metal matrix composite (HMMC) through the stir casting approach. During the stir casting process, the melting action of the material emanates numerous gases and residuals apart from the expected composite. The residuals have numerous environmental concerns, which require discussion since some of the vapors and substantial waste can lead to detrimental effects on the environment in terms of air and soil pollution.
