In the advanced areas of space, missile and nuclear technologies, there arise a need for machining components to maintain exact sharp edges, high accuracy, and precisely sized components. In the present era of modern machining, these requirements can be achieved with the help of advanced machining process like Abrasive Jet Machining (AJM).This paper presents an extensive review of the current state of research and development on abrasive jet machining process.

This paper demonstrates the new multi criterion decision making (MCDM) techniques were used, i.e. the weighted aggregated sum and product assessment (WASPAS) technique. This involves the modified air abrasive jet machining (MAAJM) of Nickel 233 alloy using carbide coated nozzle in 3mm dia with three responses are considered as against the process variables of injecting pressure, standoff distance, and abrasive mesh size. The optimal combination of MAAJM process parameter for simultaneous minimization of taper angle, surface roughness and maximization of MRR are injecting pressure of 0.686MPa, standoff distance 9mm and abrasive mesh size 400µm with 3 diameter carbide coated nozzle. The optimal results attained with the WASPAS technique demonstrated to good relation with another technique multi objective optimization rational analysis (MOORA).
