Electrochemical Machining(ECM), Laser Beam …

Disadvantages of Electrochemical Machining(ECM) Process: Workpiece material must be electrically conductive. Out of all the Non-traditional machining methods, electrochemical machining requires the highest specific cutting energy Therefore, the cost of machining will be high. This is preferable for producing contours only but not for holes.

On the application of electrochemical machining …

The process is carried out by passing an electric current through an electrolyte flowing within the inter-electrode gap between the tool (cathode) and the workpiece (anode). Since this machining method is achieved by electrochemical reaction, hard and difficult-to-cut materials can be machined (Domanowski and Kozak, 2001).
