Non-Traditional Machining (NTM) processes employ different forms of energy in their direct form to removal material from the workpiece. Such energy forms include mechanical energy (AJM, AWJM, USM), chemical energy (CHM), electro-chemical energy (ECM), thermal energy (EDM, LBM, EBM, PAM), etc. The mechanism of material removal also varies accordingly. As the name suggests, chemical machining employs an appropriate chemical solution to etch away material from work surface. Such chemical solution
