Abstract
The abrasive water jet (AWJ) is a non-traditional process that can be employed to machine a variety of materials that are significantly difficult to machine using conventional machining processes. This paper presents an experimental investigation conducted to evaluate the influence of the jet tilt angle, a kinematic process parameter, on the characteristics of the milled pocket as milling aluminium alloy 6065. The influences of this parameter are assessed by measuring differences in the depth of the milled pocket, the width, and the slope of the pocket wall. It is found that as the jet tilt angle decreases, it has a significant influence on characteristics of the milled pocket due to changing the material removal mechanism during the erosion process. Insight the influence of the jet tilt angle, this work paves a good fundamental for developing strategies for controlled 3D AWJ machining of complex shapes and improving the quality of the milled surfaces
