Abstract :
Carrier media plays a major role in removal of material in Abrasive Jet Machining (AJM). In this paper, an attempt has been made to use hot air as carrier media in AJM. Modified Taguchi robust design analysis is employed to determine optimal combination of process parameters. The Analysis Of Variance (ANOVA) is also applied to identify the most significant factor. It can be found that the air temperature is the most significant factor on Material Removal Rate (MRR) and Roughness of machined surface (Ra). It has been observed that there is good agreement between the predicted values and experimental values of optimization. The influence of temperature on MRR and Ra has been discussed. It can be found that at high temperature, there is a sufficient evidence of more plastic deformation accompanied by brittle fracture failure which results in increase of MRR and reduction of roughness
