Abrasive jet machining is a non-traditional machining process which is mostly used in machining of hardened metals. In this machining process a focus stream of abrasive particles are forces to impinge on work piece at high velocity. These high velocity abrasive particles remove metal by brittle fracture or erosion from work piece.
