Abstract
In this paper, material removal rate (MRR) of near dry EDM which use two-phase liquid and gas instead of single-phase liquid dielectric medium is investigated. Experiment is conducted with a Taguchi OA L9 considering three input parameters viz. discharge current, duty factor and tool rotational speed with three levels each. The effect of input parameters on MRR is studied. The experimental results show that discharge current is the most effective input parameters on the MRR followed by the duty factor. Moreover, discharge current has most percentage of contribution of 91.51% and duty factor has 10.5% on MRR. The empirical models of MRR are formulated from the experimental results. Finally, the empirical models are examined and validated.
