In this presentation, the development of analytical model for the prediction of the kerf profile and the kerf characteristics of single-layered structures (SLSs) and double-layered structures (DLSs) with abrasive waterjets (AWJs) are presented. The models are developed by considering the effects of the AWJs (waterjet pressure, jet traverse rate, abrasive mass flow rate, standoff distance), workpiece properties (thickness, resistance to erosion, stacking sequence), effect of interaction between the abrasive velocity profile and the abrasive distribution across the cross-section of the jet, and the effect of stacking materials on the kerf (geometry and characteristics). Further, the specific cutting energies of the constituent materials used for the construction of the SLS and DLS were determined experimentally. In addition, a new parameter, depth of damaged region was introduced and used for the determination of the top kerf widths. The performance of the model was evaluated by comparing the kerf profile and characteristics of specially fabricated workpieces (SLS: MS and Al; DLS: MS-Al and Al-MS). It was found that the predicted kerf profiles of both SLS and DLS matched the experimentally observed kerf profiles. Further, the kerf characteristics were predicted with good accuracy and also captured the effect of variation in AWJ process parameters.
