Abrasive Jet Machining (AJM) is a non-conventional machining process that carried a high-pressure air stream with small abrasive particles to impinge the work surface through a nozzle. In this paper drilling experiment was done on glass as the work piece and aluminum oxide (Al2O3) as abrasive powder on AJM. The effect of Overcut (OC) and Material Removal Rate (MRR) of glass material was finding by using L9 Orthogonal Array (OA) based on Taguchi design. The multi-objective optimization of AJM process using the Taguchi’s quality loss function has been carried out for responses of AJM. The air pressure and stand-off-distance are considering control parameter.
