Study on Waste Reduction through Maximum Service Life Analysis of Electrolyte in Electrochemical Machining

This study aims to analyze the maximum service life of electrolytes used in Electrochemical Machining (ECM) to minimize chemical waste. In ECM processes, electrolytes are often discarded prematurely due to the absence of clear guidelines, resulting in increased waste and operational costs. To address this issue, a monitoring system equipped with pH, turbidity, temperature, and conductivity sensors was developed to measure electrolyte conditions in real time. The collected data was analyzed to determine the point at which the electrolyte can no longer be effectively used without compromising machining quality. The findings provide valuable insights into extending the electrolyte’s usage period, thereby reducing waste and enhancing the sustainability of ECM operations. This research contributes to improving resource efficiency and promoting environmentally friendly manufacturing practices.
