Fig. 1.1 Schematic principle of Electro Chemical Machining (ECM)
1.2 Principle of ECM
Electrochemical machining removes material from the work piece by electrochemical process. The working principle is anodic dissolution in which the work piece as anode and the tool as cathode. Both electrodes are immersed in the electrolyte and electrical applied to these electrodes. The electric conduction is achieved through the movements of ions between the anode and cathode through the electrolyte. The current is passing through the system of arrangements will cause the dissolution of anode. This process of electrolysis is working based on Faradays law of electrolysis. The principal and process detailing of ECM for steel is shown in Figures 1.1 and 1.2, generally a neutral salt solution of sodium chloride (NaCl) is taken as the electrolyte.

1.3: Process details of Electrochemical Machining.
Unlike traditional cutting methods, work piece hardness is not a factor, making ECM suitable for difficult-to-machine materials. Takes such forms as electrochemical grinding, electrochemical honing and electrochemical turning. The process schematic is such that a cathode (tool) is advanced into an anode (work piece). The pressurized electrolyte is injected at a set temperature to the area being cut. The feed rate is the exact same rate as the rate of liquefaction of the material. The area in-between the tool and the work piece vary within .003 in. And .030 in.
1.3 Process Parameters
The operating parameters which are within the control of the operator and which influence ECM process capabilities can be described as follows:
i. Feed Rate
A high feed rate results in higher metal removal rate. It decreases the equilibrium machining gap resulting in improvement of surface finish and tolerance
