Abrasive Water Jet Machining (AWJM) is the non-traditional material removal process. It is an effective machining process for processing a variety of Hard and Brittle Material. And has various unique advantages over the other non-traditional cutting process like high machining versatility, minimum stresses on the work piece, high flexibility no thermal distortion, and small cutting forces .
