AHP-WASPAS Approach for Choice of Non-Conventional Manufacturing Process

Abstract

Titanium, ceramics, composite materials, and stainless steel are just a few examples of the high-strength, high-hardness materials that are increasingly being used in industries like aerospace, nuclear power, and steam turbines, and these materials are typically processed using a wide range of NTM techniques. However, these NTM methods require a single ideal NTM procedure for a specific material for cost-effective machining because to their excessive power requirements and high costs. Choosing the best method, however, may be a time-consuming ordeal. There are several different components that go into deciding which machining technique to use. To choose the best non-traditional approach, it is recommended to use a combination of "the Weighted aggregated sum product assessment" (WASPAS) and an "Analytical Hierarchy Process" (AHP). Using a combined approach, we determined that PAM is the best possible NTM process out of the following options: AJM, CM, EDM, EBM, USM, ECM, LBM, WJM, PAM, WEDM and AFM.
