Non-Traditional Machining Processes Prof. J. Ramkumar Department of Mechanical Engineering IIT Kanpur October 17, 2017
Outline Evolution of Non-Traditional Machining Classification of Advanced Machinig Processes Mechanical Machining Electro-Thermal Machining Laser Beam Machining
Limitations of Conventional Machining Methods I Increased workpiece hardness : decreased economic cutting speed. Hence, lower productivity. I Rapid improvements in the properties of materials (hardness, strength, etc) I Requires much superior quality of tool materials. I Tool material hardness should be greater than workpiece hardness.
