Electrochemical machining (ECM) is nontraditional machiningwhich is used to remove metal by anodic dissolution. In this study themetal workpiece (WP) was stainless steel (AISI 316) and potassiumchloride (KCl) and potassium sulphate (K2SO4) solutions were used aselectrolyte, and the tool was used from copper. In this work theexperimental parameters that used were concentration of solution,current and voltage as input. While surface roughness (Ra) and materialremoval rate (MRR) were the output. The experiments on electrochemicalmachining with using concentration (10, 20 and 30) g/l, current (2, 5 and10) A and voltage (6, 12 and 20)V. Gap size between tool and WP (0.5)mm. The results showed that (K2SO4) solution gave surface roughnessand material removal rate less than (KCl) solution in all levels, maximum(Ra) is (0.471) and minimum (0.049), while (KCl) solution gavemaximum (Ra) was (4.497) and minimum was (0.837). Generallyincreasing in machining parameter (concentration of solution, currentand voltage) lead to increase in (Ra) and (MRR). This study aims tocompare the effect of using different electrolyte solution includingpotassium chloride (KCl) and potassium sulphate (K2SO4) on the surfaceroughness (Ra) and material removal rate (MRR).
