• Generally macroscopic chip formation by shear deformation
• Material removal takes place due to application of cutting forces – energy domain can be
Classified as mechanical
• Cutting tool is harder than work piece at room temperature as well as under machining
Conditions
Non-conventional manufacturing processes is defined as a group of processes that remove excess material by various techniques involving mechanical, thermal, electrical or chemical energy orcombinations of these energies but do not use a sharp cutting tools as it needs to be used for traditional manufacturing processes. Material removal may occur with chip formation or even no chipformation may take place. For example in AJM, chips are of microscopic size and in case of Electrochemical machining material removal occurs due to electrochemical dissolution at atomic level.
