Abstract: Machining of hard-to-cut materials to high precision level is a prerequisite in fabricating various intricate engineered components in both a macro and micro scale. One of the most common but also a demanding task is the drilling of deep holes having small diameters, to the required degree of accuracy, using abrasive waterjet machining. In this paper, an experimental investigation of drilling high aspect ratio holes with abrasive waterjet machining is presented. A multivariate analysis method was invited to study the effect of different input parameters on various machining performance measures such as material removal rate and kerf characteristics in a full factorial design of experiment. The statistical models to predict the process response variables investigated are as well presented

Key words: Abrasive waterjet, aspect ratio, removal rate, standoff distance, taper angle.
