Abstract

The research focuses on static Electrochemical Machining (ECM) applied to 304 stainless steel samples to determine the optimal parameter combination for achieving high material removal rates (MRR) and a consistently smooth surface. Previous studies have extensively explored Electrochemical Machining, while this research approach incorporates ferric nitrate to expedite the ECM process. The study examines various variables, including 25°C, 40°C, and 50°C temperatures, alongside different ferric nitrate concentrations (ranging from 0% to 5%) at 10V, 15V, 20V, and 25V. The ECM procedure is conducted within an acrylic enclosure, utilizing 304 stainless steel as the anode and gold as the cathode, interconnected via a cable to a DC power source. The research identifies an optimal parameter combination: operating at 50°C with 1% ferric nitrate addition and a voltage of 20V. This configuration consistently yields high MRR values while ensuring a uniformly smooth surface on the test specimens.
