Abstract
This paper thoroughly examines the development of a prediction model for key process parameters, along with its evaluation through rigorous experimentation, to enhance the cutting performance of Abrasive Water Jet (AWJ) machining. Numerous analytical and predictive models for forecasting penetration depth in AWJ machining have been reported by various researchers. In this work, a dimensional analysis approach is employed to develop a predictive model for penetration depth that incorporates the kerf wall drag coefficient and applies the boundary layer theorem. The study experimentally investigates several ferrous and non-ferrous workpiece materials, such as EN 8 steel and alumina ceramic. Experiments on two distinct target materials utilizing two different AWJ machine setups show good agreement with the proposed model. The industrial application of these models will increase understanding of the complex AWJ machining process and reduce the need for costly experiments in the future.
