Abstract

In the manufacturing industry, to produce high-quality products at a reasonable cost, Optimization is a useful technique for determining the optimal production conditions. The focus of this research is to learn more about the influence of input parameters and determine the best settings for these variables to maximize MRR while decreasing SR and TWR while using Nimonic 90 NPEDM.The EDM characteristics of peak current, MWCNT powder, and nano Al powder were measured at three different levels using the L27 orthogonal array (OA). To improve the response parameters of material removal rate (MRR), surface roughness (SR), and tool wear rate, data envelopment analysis-based ranking method (DEAR) is widely used .The ideal values are achieved at MWCNT 0.5g/l, nano Al powder 2g/l, peak current 15 Amp, respectively, based on the findings of calculated Multi performance rank index (MRPI) values. MWCNT and peak current (Ip) discovered to be the most effective important parameters impacting quality attributes based on the results of the ANOVA.
