EMPIRICAL ASSESSMENT AND MODELING OF MRR AND SURFACE ROUGHNESS ACQUIRED FROM WIRE ELECTRICAL DISCHARGE MACHINING OF INCONEL 718

The primary objective of the current experimental work is to pick up the ultimate consequential cutting factor set in wire electrical discharge machining (WEDM) of Inconel 718 for the purpose of acquiring greater MRR and elegant surface quality for machined samples. Input variables of WEDM such as spark voltage, pulse on time, wire tension, and dielectric pressure have been taken for analysis. L12 Taguchi orthogonal arrays have been adopted for the desirable planning of experimental run. A series of cutting operations are effectuated on Inconel 718 material by taking the different combination of machining factors. The MRR is measured for the entire machined sample and surface roughness is also probed properly. Taguchi method and linear model analysis have been exploited in order to optimize machining variables and to correlate the input variables and response variables. Analysis of variance is also accomplished in order to identify the significant cutting factor of WEDM process in cutting Inconel 718.
