“…In view of the palm oil's enriched oxidation, the sparking cycle is more effective, resulting in an increased TWR. 34 Moreover, when EDM oil is used, more amount of carbon is adhered on the surface of electrode resulting low conductive carbide layer and hence less heat is conducted into tool electrode, resulting low TWR which promotes in an extension of the tool's useful life and a reduction in the cost of producing the tool electrode. The same is also observed from optical image of tool tips, as shown in Figure 5.…”

In electrical discharge machining, the material removal phenomenon is heavily influenced by the breakdown strength of the dielectric fluid and the inter-electrode gap monitoring. This innovative research addresses a comparative performance evaluation and sustainability assessment between biodegradable palm oil and conventional EDM oil during machining of stainless steel (SS-316) using copper electrode. The cutting performance is investigated by comprehensive result analysis of various machinability aspects including material removal rate, surface integrity, tool wear rate, radial overcut of machined components. According to the findings, machining with palm oil dielectric outperformed the usual EDM oil with regards to improved material removal, surface morphology and finish, increased machined surface hardness with minimum surface crack density and hole overcut. Pyrolysis of conventional EDM dielectric oil leads to deposition of thin film carbon on bottom surface of the copper electrode which prevents the quick tool wear due to its higher breakdown voltage. The total machining cost expenditure per component under palm oil (INR383) is reduced by 11% than expenditure in traditional EDM oil (INR426). Compared to EDM oil, machining under biodegradable palm oil as dielectric fluid is better socio-economical viable and environmental conscious to enhance sustainability.

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
