ABSTRACT
This chapter introduces for the Non-Traditional Machining (NTM) Processes, their classifications, advantages, and limitations. The traditional methods using cutting tools are found to be unsuitable to machine Difficult-To-Cut (DTC) materials economically and there is no possibility that they can be further developed to do so, because most of these materials are harder than the materials available for use as cutting tools. Non-traditional processes are capable to machine a wide spectrum of metallic and non-metallic materials irrespective of their hardness or strength. These are non-traditional in the sense that-traditional tools are not employed; instead energy in its direct form is utilized. However, NTM-methods cannot replace the traditional machining (TM) methods. They can only be used when they are economically justified or it is impossible to use TM-processes.
