Abstract
Research on static electrochemical machining processes carried out on Stainless steel 304 or AISI 304 specimens to determine the optimum combination of parameters to produce surface roughness with a high MRR value or feed rate. Static electrochemical machining research does not involve the presence of flow by combining various parameters to produce the desired goal. This study's voltages are 10, 15, 20, and 25V, with temperatures of 25, 40, and 50 0C. The time used is 1 minute, and using the test solution, NaNO3 added Ferric Nitrate in the content of 1%, 3%, and 5%. The selected test place uses acrylic material and is connected with a cable connected to the DC Power Supply. Then, the finished test object is taken macro images to see the surface of the test object. After that, microscopy was carried out using an optical microscope to determine the topography of the test so that the results obtained on the test object showed that there had been intergranular corrosion on the surface and got good test object surface results.
