Classification of Non Conventional Machining Process

Classification of non-conventional machining process :

They are classified in the various groups according to the type of fundamental machining they employ named mechanical, electrical, chemical, electro-chemical, thermo-electric etc.

They are classified according to energy used, the mechanism of metal removal in the process and the medium for transfer of those energies etc.
