1 Nontraditional Machining Processes Nontraditional Machining Processes (NTM) ME 202 Manufacturing Technologies ME 202 Manufacturing Technologies 2 Nontraditional Machining Processes Machining processes that involve compression-shear chip formation have the following disadvantages. 1. High (cutting-clamping) forces create problems in regard to holding the workpiece and cause distortion , 2. Large amounts of energy causes problems of heating (and cooling ), 3. It is an expensive process, since large amounts of energy is used in producing chips, end energy and money are required to remove, dispose and recycle chips. 5. Mostly burrs are formed, 6. There are limitations in regard to the delicacy and/or complexity of the work that can be done, As a result of these disadvantages, Non-Traditional Machining Processes (NTM), that do not involve the formation of chips by shear deformation have been developed.
