Abstract:This present work is aimed to optimize the machining parameters and study the
effect of powder mixed dielectric fluid on EDM process. TOPSIS method of
optimization is adopted to identify the optimal machining parameters. HCHCr
die steel is preferred as machining material. Ni, Zr and Ni+Zr were selected
as powder inclusion in dielectric fluid due to hard and ductile nature. L9
array Taguchi DOE is preferred to perform the experiments with parameters
like peak off time, pulse off time and pulse… Show more
