    - The shapes and cavities, which are extremely difficult and costly to machine with conventional machining processes, can be produced by Electro-Chemical Machining (ECM)

    - The advantages of ECM process are as follows:

    1. The ECM process is capable of machining metals and alloys irrespective of their strength and hardness.

    2. The cutting forces are not involved in the ECM process.

    - There are also some disadvantages of ECM process.

    1. The ECM process consumes very high power.

    2. The floor space required for ECM process is large.
