Multi-criteria decision making in electrical discharge machining with nickel coated aluminium electrode for titanium alloy using preferential selection index

In the present scenario, great effort is expended to improve machining process by adopting multi-criteria decision making in electrical discharge (EDM). this research article, an attempt was made optimize parameters of EDM with Nickel Coated Aluminium Electrode for Titanium Alloy using Preference Selection Index (PSI). The experimental work were performed Taguchi based L16 orthogonal solve multi-objective optimization problem. current ( I ), voltage U ) and pulse on time T used as input response variables investigation while material removal rate (MRR) tool wear (TWR) selected performance measures. results show that set optimized problem nickel coated aluminium electrode could better surface measures less deviation from prediction. combination between PSI method reduced saved significantly cost increased accuracy process.
