Abstract: Electrochemical machining (ECM) is a technique of eradicating metal by an electrochemical procedure. It utilizes an electrolyte and electrical current to ionize and eradicate metal atoms. Electrochemical Machining is a relatively ancient machining system which basis were laid way backside in the 19th century. The process has enhanced extremely everlastingly since, thus becoming an extremely defined practice with gigantic limitless application possibilities across engineering. In this research paper our emphasis would be on understanding the operating principles of electrochemical machining and to know its economical impact. We will also discuss the advantages and disadvantages of ECM and its applications.

Operating principle: Electrochemical machining is a procedure of a choosy dissolution of the anodically linked work piece material submerged in an electrolyte collectively with an anodically connected device.
Predominantly electrochemical machining is alike Electro polishing where the work piece surface unevenness diminishes due to the changing of the atoms into ions and their removal from the surface as a result of a passage of an electric current.
Electrochemical machining is in general differing to electroplating where the metallic ions wandering through the electrolyte solution set down on the surface of the cathodically connected work piece.
The electrochemical reactions taking place in the electrochemical machining process are as …show more content…
Power supply- The power needed to operate the ECM is observably electrical. There are numerous requirement s to this power. The current density must be high. The gap between the tool and the work piece must be low for high accuracy, thus the voltage must be small to prevent a short circuit. The control system uses some of this electrical power.
B. Electrolyte circulation system- The electrolyte must be injected in the gap at high speed (between 1500 to 3000 m/min).The inlet pressure must be between 0.15-3 Mpa. The electrolyte system must include a fairly strong pump.
C. Control system-Control parameters include: Voltage, Inlet and outlet pressure of electrolyte, Temperature of electrolyte. The current is dependent on the above parameters and the feed rate.
D. Machine - The machine is a major subsystem of the ECM. It includes the table, the frame, work enclosure (prevents the electrolyte from spilling), the work head (where the tool is mounted).The tools (electrodes) are also part of the machine system.
IV Advantages:
1. There is no cutting forces therefore clamping is not required except for controlled motion of the work piece.
2. There is no heat affected zone.
3. Very accurate.
4. Relatively
