【 摘 要 】

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. Box Behnken Design of Response Surface Methodology is used to study the parametric effect on responses. Finally, a single experiment is performed at the predicted optimal condition, obtained from the multi-response particle swarm optimization to validate the model.
