ABSTRACT = {The purpose of this research is to obtain the optimum cutting parameters to achieve the dimensional accuracy
of Nimonic alloy miniature gear manufactured using Wire EDM. The cutting parameters investigated in this
study are current, pulse on time (PON), pulse off time (POFF), wire tension (WT) and dielectric fluids. Ethylene
glycol, nanopowder of alumina and oxygen are mixed to demineralized water to prepare novel dielectric fluids.
Deviation in inner diameter, deviation in outer diameter, deviation in land and deviation in tooth width are
considered to check the dimensional accuracy. Taguchi L<sub>16</sub> is employed for experimental design and multiple
response optimization is performed using Entropy TOPSIS and Pareto ANOVA. Results indicate that pulse on
time is the most notable parameter for good dimensional accuracy followed by dielectric fluid, current, pulse off
time and wire tension. Ethylene glycol mixed demineralized water is preferred for low dimensional deviation. The
optimum WEDM parameters are pulse on time at 20 μs, Ethylene glycol mixed demineralized water dielectric
fluid, current at 3 A, pulse off time at 4 μs, and wire tension at 18 N.},
