Non-Traditional Machining Process Selection

Abstract

In the contemporary world, manufacturing by means of non-traditional machining (NTM) processes is gaining profound importance. However, there remains a plethora of choices for machining a particular product with desired accuracy and surface finish. This research delves into the need for selecting the best possible NTM machine which can produce a specific shape on a particular job material. In the work, initially analytic hierarchy process has been applied to find the relative importance of various NTM processes on the basis of combination of features pertaining to a product as well as process. Finally, using quality function deployment methodology a complete solution in terms of scores have been estimated for various NTM processes considering various shape features and work material combination. Also, the possible variance in the process capability features are taken to account during the analysis. The result obtained shows that electro chemical machining process overrules other NTM processes with reference to production time, radii at corner, surface finish, and tolerance.
