Abrasive water jet machining (AWJM) is one of the modern machining process that came into existence during the last quarter of 20th century . AWJM involves the high pressure (typically 200–350 MPa) water that is accelerated by a fine orifice (typically diameter 0.24–0.40 mm) containing abrasive particles (typically mesh size#50–#120) on ...
