In Electrochemical grinding, the metal bonded grinding wheel filled with a non-conductive abrasive. The grinding wheel act as a cathode and the workpiece is act as an anode. The electrolyte, which is usually sodium nitrate, sodium chloride, potassium nitrite, with a concentration of 0.150 to 0.300 kg/litre of water.grinding effect, EDM effect and ECM effect namely the Grinding-aided Electrochemical Discharge Ma-chining (G-ECDM) process to machine MMCs [27]. The process is different from the electrochemical grinding (ECG) process which only involves elec-trochemical action and grinding without the EDM action. Also, the ECG process removes the bulk
