Abstract
The sustainability of Electrical Discharge Machining (EDM) is a green technology which is able to produce a green environmental condition and healthy human condition. The characteristics of hydro-carbon based dielectrics are identified to have disturb the machining performance due to their carbon properties, more debris formation, recast formation and formation of oxide on processed surface.To achieve the green technology in machining, decrease the environmental impact, reduce the machining cost and save energy, neem oil is employed as a bio-dielectric fluid. Hence, the circular holes have been carried out on AA8011/SiC/Si3N4 composites in EDD using a neem oil. The responses, Rate of Material Removal (MRR), Rate of Electrode Wear (EWR) and Surface Roughness (Ra) produced results with neem oil are analyzed to virgin kerosene and Cu-Si in kerosene dielectric. The XRD report produced that the Mg2Si and MgAl2 intermetallic phases have been formed in composites. The higher improvement in 67.5% MRR, 26% EWR and 24% Ra has been achieved using neem oil. The pulse duration has highly contributed for improving the selected responses and identified by using an Analysis of variance (ANOVA). The ELimination Et Choix Traduisant la REalite (ELECTRE) has found an optimum factor value of 500 µs pulse duration, 55 µs pulse interval, 4 A current and 45 V gap voltage.
