Electrochemical Machining (ECM) is a non-traditional machining process that removes material through electrochemical reactions rather than mechanical interaction. This makes it suitable for machining hard, brittle, and thermally sensitive materials used in advanced engineering applications. This study presents a comprehensive investigation into the influence of key ECM parameters—voltage, feed rate, electrolyte concentration, and inter-electrode gap—on material removal rate (MRR), dimensional accuracy, and surface finish. Experiments conducted on stainless steel workpieces revealed that increasing voltage significantly enhances MRR, while moderate electrolyte concentration improves machining stability and reduces pitting. Lower feed rates improve surface integrity but may compromise productivity. The study identifies an optimal parameter combination that balances precision and efficiency, contributing to improved machining strategies for industrial applications requiring high accuracy and minimal surface defects.
