Abstract

The demand for micro products is rapidly increasing in chemical, marine and aerospace industries. The super alloys which have high strength and corrosion resistance properties play a major role here. Hastelloy, one of the super alloy which is difficult to machine by the conventional machining processes can be machined by a unconventional machining process named Abrasive Jet Machining. Abrasive jet machining is a process in which the metal removal takes place due to the impact of air+abrasive particles on work surface .The erosion of work takes place due to the mixture of air and abrasives.Hastelloy C276 sheet of thickness 1mm has been drilled on the AJM test rig using variable process parameters. In this paper optimization of process parameters of Abrasive Jet Machining of Hastelloy C276 by RSM methodology is presented. The values obtained in RSM Analysis was compared with the Analysis of Variance (ANOVA).Various levels of Experiments are conducted using L15 Orthogonal Array for both MRR and KERF.
