Analysis of Electrochemical discharge machining by bipolar fuzzy WASPAS method

Abstract

Weighted Aggregated Sum Product Assessment (WASPAS) is the consolidation of familiar MCDM patterns, Weighted Sum Model (WSM) and Weighted Product Model (WPM) which provides enhanced ranking accuracy. Electrochemical discharge machining (ECDM) process for creating micro-drills on silicon nitride a non-conducting ceramic is considered. The working of ECDM mechanism is predominantly affected by parameters such as voltage applied, electrolyte concentration and inter electrode gap. The appropriate parametric combinations to attain the preferred levels of mechanizing rate and accuracy are determined using WASPAS method.
