“…13 As the EDM process depends on the flow of electrons and their collision with one another also with the medium; hence the nature of the dielectric medium also plays a significant role in determining the nature of the final machined surface. Experiments conducted by Niamat et al 36 and Kumar 37 with distilled water and kerosene showed higher MRR for kerosene dielectric than distilled water due to arcing taking place in distilled water. It also showed a lower electrode wear rate (EWR) in the case of kerosene due to the formation of carbon on the electrode.…”

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.

“…HMMC materials are challenging to machine using traditional methods due to their high reinforced strength, so the machining of these HMMC's is usually done by non-traditional machines. Electric Discharge Machine (EDM) is an unconventional machine used for machining materials possessing high hardness and specific strength like superalloys, Metal Matrix Composite (MMC) and HMMC [3]. The background of the EDM process began with Joseph Priestly's findings in 1770.…”

The tendencies of using composite materials are increasing rapidly in advanced engineering and technology applications. Ceramic reinforced aluminum composites are difficult to machine by conventional machining processes. In this work, ceramic reinforced aluminum composites are machined by Electric Discharge Machine (EDM). The goal of this study is to focus on the influence of EDM settings on Al6061 Metal Matrix Composite (MMC) reinforced with Silicon Carbide (SiC) and Boron Carbide (B4C) particles. The MMC is prepared by stirring casting route, then the workpiece is mounted on the electric discharge machine to perform the machining. Because MMC contains high abrasive ceramic (SiC and B4C) particles that are difficult to machine using traditional machining methods, an electrical discharge machine is used for machining. The experiments were conducted with four process parameters like Pulse current (I), Pulse off Time (P-Off), Pulse on Time (P-On), and Tool Lift (TL) with three levels in each parameter to examine the response measures such as Material Removal Rate (MRR), Surface Roughness (SR), Tool Wear Rate (TWR) and Surface Crack Density (SCD). The experimental results reveal that the surface crack density, MRR, SR, and TWR increases with an increase in current and pulse in time.The optimal combinations of process parameters were identified. Obtained optimal machining conditions are I input level at 9 Amps, P-On input level at 20 µs, P-Off input level at 50 µs, and Tool Lift input level at 4.5 µs with results of 0.103g/min MRR, 0.022 g/min TWR, 4.108µm SR and 0.0048 µm SCD.

“…The total carbon emissions during fabrication processes can be calculated by total energy used for the fabrication process and machining processes, which can be calculated by software like GaBi. Further, sustainable machining for composite materials like Dry machining of composites, 52 Dry-EDM processes 53,54 and machining with eco-friendly oils are the popular research areas at present time, which are contributing to promote sustainability in the area of composite materials.…”

In the last few decades, man has become more innovative in discovering new materials to make his life more sustainable. Copper metal matrix composite is the most promising material for many engineering applications where the higher temperature resistance and good microstructural stability is required. The sustainable development of copper metal matrix composite is based on the use of ceramics as reinforcements. The choice of reinforcement material is highly influenced by their mechanical properties such as hardness, wear resistance, cost advantage, availability in market and refractory nature. In the current scenario, copper and its alloy are gaining popularity due to their high sustainability, high conductivity and good corrosion resistance. However, the relatively low wear resistance and high temperature strength restrict the use of copper in many applications. Recent developments in metal matrix composites have provided new means to produce high sustainable copper metal matrix composite materials with high wear resistance and high strength materials. It has been found that the wear resistance and strength of materials can be improved by adding hard ceramic particles such as Al2O3, SiC, TiC and ZrO2 into the metal matrix. The aim of the present study is to summarise the research work carried out in the field of sustainable copper metal matrix composites. It also reports the various manufacturing routes along with the structural, mechanical, electrical and corrosion properties. It is found that copper metal matrix composites are preferred over the conventional composites. Sustainability issues around the globe has forced the industries to adopt the eco-friendly materials with their fabrication and machining routes, which results in less carbon emission and also has less affect to the environment. Fabrication of eco-friendly composites is an emerging research area, which has made several research scopes in production of sustainable composites. It is expected that this study can be beneficial for the researcher to decide their research direction in the field of sustainable material production.
