• Traditional machining is mostly based on removal of materials using tools that are harder than the materials themselves.
• New and novel materials because of their greatly improved chemical, mechanical and thermal properties are sometimes impossible to machine using traditional machining processes.
• Traditional machining methods are often ineffective in machining hard materials like ceramics and composites or machining under very tight tolerances as in micromachined components. • The need to a avoid surface damage that often accompanies the stresses created by conventional machining. Example: aerospace and electronics industries.
• They are classified under the domain of non traditional processes.
