This paper is focused on drilling of K-60 alumina ceramic using various grades of hot abrasives at different temperatures with pressurized and fluidized bed abrasive jet machining (FB-AJM) process. The fluidized bed mixing chamber, pressurized powder feed system, and abrasive heating chamber are fabricated and modified to study the effects of different machining parameters, like, pressure, standoff-distance, grain size, and temperature on material removal rate and taper angle.
