KERF CHARACTERISTICS IN ABRASIVE WATERJET CUTTING OF CERAMIC MATERIALS

An abrasive water jet (AWJ) can provide a more effective means for pre cision cutting of ceramic materials as compared with conventional mach ining methods, but many aspects about this cutting technology are stil l under flux and development. In this study, experimental techniques b ased on statistical experimental design principles and theoretical inv estigations were conducted to study AWJ cutting of alumina-based ceram ics. Semi-empirical cutting depth equations are determined for the pre diction and optimization of the AWJ cutting performance. Topographical characteristics of uncut-through kerf and the effects of various para meters are discussed. In addition, visualization studies are conducted to develop further understanding of the macromechanics of the AWJ cut ting process. Copyright (C) 1996.
