    - In Electrical Discharge Machining (EDM) process, the metal removal is carried out by melting and vaporization as there is a controlled erosion between two electrically conducting materials, the tool and the workpiece.

    - In Electro-Chemical Machining (ECM) process, the metal removal is carried out by electrosysis

    - Whereas in Ultrasonic Machining (USM) process, the metal removal is carried out by fracture of work material due to impact of grain
