Electrochemical machining works on the Faraday law of electrolysis which state that if two electrode are placed in a container which is filled with a conductive liquid or electrolyte and high ampere DC voltage applied across them, metal can be depleted form the anode (Positive terminal) and plated on the cathode (Negative terminal).
b) Electrochemical machining (ECM): This is based on dissolving ions of the processed material (metal) in the area around the tool, which is the electrode (-) of the DC source and the processed part is the (+), the ions thus being removed from the conductive electrolyte.
Electrochemical machining is a process of a selective dissolution of the anodically connected work piece material submerged in an electrolyte together with an anodically connected tool. Principally electrochemical machining is similar to Electropolishing where the work piece surface roughness decreases due to the conversion of the atoms into ions and their removal from the surface …
