Correct option is A
Electrochemical Grinding (ECG) is a
hybrid machining process that combines
electrochemical machining (ECM) and conventional grinding. In this process, material removal occurs through
electrochemical dissolution rather than mechanical abrasion. The
workpiece acts as the anode, the
grinding wheel (coated with abrasive particles) acts as the cathode, and an
electrolyte (conductive fluid) is used to carry away the dissolved material.
As the electric current passes through the electrolyte, the metal from the workpiece
dissolves into the conductive fluid rather than being physically cut or melted. This process results in
no burr formation, minimal heat generation, and excellent surface finish.
