Material Removal Rate on Electrochemical Machining of

MRR on electrochemical machining has been observed. The type of material has effect to the MRR. On average, MRR of brass is 2.96 x 104. g/s, stainless steel has MRR 2.54 x 10. g/s, and MRR aluminium is 7.9 x 105. g/s. The ECM has been done initially using 2 mm of brass rod electrode and 1 mm thickness of workpiece material. For 6 mm of brass electrode, the MRR becomes 5.74 x 104. g/s and 2
