A new model for predicting the depth of cut in abrasive waterjet contouring of alumina ceramics

A new predictive model for the depth of cut in abrasive waterjet (AWJ) contouring of alumina ceramics is developed using a dimensional analysis technique. The model is then experimentally verified when cutting an 87% alumina ceramic within the practical range of process variables. It is found that the model can give adequate predictions of this cutting performance measure with about 1% average error.
