Design, modeling and parametric optimization of WEDM of Inconel 690 using RSM-GRA approach

Design, modeling and parametric optimization of WEDM of Inconel 690 using RSM-GRA approach Wire electric-discharge machining (WEDM) is the most desirable material processing technique for making complex designs, especially in hard-to-machine conductive materials with high fidelity and accuracy. Current study aims to streamline the WEDM parameters to process Inconel 690. Experimental trials are effectuated using Box-Behnken design of response surface methodology. Processing conditions of parameters are varied to scrutinize the performance of the technique. Federated mode of analysis of variance and grey relational analysis (GRA) are implemented to the study the significance and streamlining of the parameters respectively, to attain increasing material removal rate and small surface roughness for inconel 690 which is highly preferred for nuclear reactor and gas turbine industry. After applying GRA technique, streamlined condition of parameters is found which gives results with acceptable error.

Abstract

Wire electric-discharge machining (WEDM) is the most desirable material processing technique for making complex designs, especially in hard-to-machine conductive materials with high fidelity and accuracy. Current study aims to streamline the WEDM parameters to process Inconel 690. Experimental trials are effectuated using Box-Behnken design of response surface methodology. Processing conditions of parameters are varied to scrutinize the performance of the technique. Federated mode of analysis of variance and grey relational analysis (GRA) are implemented to the study the significance and streamlining of the parameters respectively, to attain increasing material removal rate and small surface roughness for inconel 690 which is highly preferred for nuclear reactor and gas turbine industry. After applying GRA technique, streamlined condition of parameters is found which gives results with acceptable error. Surface topography of the post processed workpiece is also anatomize using scanning electron microscopy.
