“…Results revealed that the biodiesels offered higher MRR at top most energy settings compared to mineral oil and suggested that the biodiesels alternative to mineral oil [20]. An investigation was conducted to analyze the impact of current based parameters on response measures and found that the pulse on time had a greater impact on MRR as compared to nonelectrical parameters namely feed rate and spindle speed [21]. Surface morphology of debris particles obtained while processing SKD 11 with kerosene and eco-friendly oils at different input condition was analyzed.…”

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
