“…The results of mineral oils using as dielectric medium proven that superior in terms of MRR and surface finish compared to ecofriendly oil. Hence, researchers are proposed that machining efficiency can be improved by addition of nano powder in eco-friendly oil [2][3][4][5][6][7]. Feasibility of biodiesels using as a dielectric medium for EDM of Ti alloy at various input parameter settings were analyzed and compared output measures of biodiesels with kerosene under same parameter settings simultaneously.…”

µED-milling is an excellent micro machining process for machining of complex micro structures on conducting materials. In this paper, the feasibility of SiC nano powder mixed Pongamia BD as a dielectric medium while µED-milling of Inconel 718 alloy at different parametric settings namely capacitance (10 nf, 100 nf, 400 nf), powder concentration (0 g/L,0.1 g/L ,0.3g/L) and voltage (120v, 130v, 140v) is analysed. Further, the craters dimensions are correlated with the 3D roughness parameters (Spk, Sk and Svk) in this investigation. Lower settings of capacitance (10nF) offered a maximum MRR (601767.1µm3/s) compared to intermediate (398080.62 µm3/s) and higher (273498.29 µm3/s ) settings of capacitance. MRR is increased around 1.3 times with Pongamia BD compared to SiC nano powder mixed Pongamia BD at considered parametric settings. Crater diameter is decreased by 24.1% with SiC nano powder mixed Pongamia BD due to lesser amount heat transfer to workpiece. Droplet angle of machined surface with SiC nano powder mixed Pongamia BD is 20% higher than Pongamia BD at considered parametric settings. Capacitance and voltage have the significant influence on crater diameter and roughness. Maximum MRR (1034239.41 µm3/s) is achieved with machining condition (10nF, 120V,0g/L) for considered biodiesels. RLT appears to be higher around 27% with the processed surface of SiC nano powder mixed Pongamia BD as compared to Pongamia BD due to reaction of powder particles with work material. 3D roughness parameters (Spk, Sk and Svk) were greatly reduced due to inclusion of powder in biodiesels

Purpose This study aims to understand the current production scenario emphasizing the significance of green manufacturing in achieving economic and environmental sustainability goals to fulfil future needs; to determine the viability of particular strategies and actions performed to increase the process efficiency of electrical discharge machining; and to uphold the values of sustainability in the nonconventional manufacturing sector and to identify future works in this regard. Design/methodology/approach A thorough analysis of numerous experimental studies and findings is conducted. This prominent nontraditional machining process’s potential machinability and sustainability challenges are discussed, along with the current research to alleviate them. The focus is placed on modifications to the dielectric fluid, choosing affordable substitutes and treating consumable tool electrodes. Findings Trans-esterified vegetable oils, which are biodegradable and can be used as a substitute for conventional dielectric fluids, provide pollution-free machining with enhanced surface finish and material removal rates. Modifying the dielectric fluid with specific nanomaterials could increase the machining rate and demonstrate a decrease in machining flaws such as micropores, globules and microcracks. Tool electrodes subjected to cryogenic treatment have shown reduced tool metal consumption and downtime for the setup. Practical implications The findings suggested eco-friendly machining techniques and optimized control settings that reduce energy consumption, lowering operating expenses and carbon footprints. Using eco-friendly dielectrics, including vegetable oils or biodegradable dielectric fluids, might lessen the adverse effects of the electrical discharge machine operations on the environment. Adopting sustainable practices might enhance a business’s reputation with the public, shareholders and clients because sustainability is becoming increasingly significant across various industries. Originality/value A detailed general review of green nontraditional electrical discharge machining process is provided, from high-quality indexed journals. The findings and results contemplated in this review paper can lead the research community to collectively apply it in sustainable techniques to enhance machinability and reduce environmental effects.
