Schematic diagram of ECD set-up. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl).
An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Electrochemical machining is the reverse of electroplating. Fig. Electrolysis is based on Faraday laws of electrolysis which is stated as. 4 Schematic view of electrolysis product distribution when using In the process, workpiece is taken as anode and tool is taken as cathode. Fig. Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece.

Electrochemical machining (ECM) is a non-traditional machining process uses the principle of Faraday to remove metal from the workpiece.
Both the tool and the workpiece are stationary.

The tool is given linear and rotary motion while the workpiece is stationary.

weight of substance produced during electrolysis is proportional to current passing, length of time the process used and the equivalent weight of material which is deposited.

Schematic diagram of (a) working principle and (b) generation of shape on anodic workpiece, in the electrochemical machining process. Wire electrochemical machining (WECM) is a promising approach for the fabrication of various metal parts. One phenomenon used to produce intense localized heat generation without using any sophisticated technology like electron beam or …
