Experimental investigation of non-edible dielectric fluid (bio-dielectric) in electrical discharge machining process

Abstract

The implementation of the perception of sustainable manufacture and the necessity to accept the standards significant for the assessment of all manufacturing process with the sustainability concept. This paper is based on experimental investigation for the advancement in dielectric medium, based on non-edible oil that is Jatropha-curcas for electrical discharge machining (EDM) process. In conventional EDM process kerosene was used as a dielectric which was unfriendly environmental and poor safety for operator, bio-dielectric fluids can increase the machining process in unconventional EDM. In this paper output (responses) results of Jatropha bio-dielectric is much better as compared to kerosene (dielectric fluid). Comparative studies of Jatropha and kerosene have been conducted which shows that the efficiency of process in term of Material removal rate (MRR) is 30–60% more and Electrode wear rate (EWR) is 20–25% less. By means of input factors pulse on time, duty cycle, peak current and gap voltage were chosen on the basis of single variable at once and DOE plans to examine the performance of proposed bio-electric and obtained output result shown the recital in term of MRR and EWR with good surface finishing.
