Abstract

Electrochemical discharge machining (ECDM) is a proven technology for machining glass work materials with effective material removal rate. In the ECDM process, electrolyte selection plays a pivotal role in controlling the gas film stability and other machining features owing to their discrete electrochemical properties. This present article investigates the effect of three different electrolytes viz. NaOH, KOH, and NaCl on the removal rate of material by using Taguchi's L9 Orthogonal array design. Electrolyte type, its concentration, and applied voltage were chosen as process parameters. Response measurements were analyzed through the S/N ratio to obtain parametric optimization for maximum removal rate of material or Material Removal Rate (MRR) values. Results revealed that the electrolyte type is the most significant parameter influencing the removal rate of material with a percentage contribution of 60.83% followed by applied voltage and electrolyte concentration. The optimum values of parameters for maximum MRR are found to be A3B1C3 i.e., (50V, NaOH, 25 wt %).
