Abrasive water jet (AWJ) machining is regarded as a high potential technology in the field of machining difficult-to-cut materials due to its great virtues. The distinct advantages over the conventional machining processes includes no thermal distortion of the workpiece, high machining versatility, high flexibility to cut in any direction, and small cutting forces.
The water jet facility has a capability of producing 55,000 psi and speeds of up to 2,000 mph. This is powerful enough to cut through materials including difficult to machine materials, such as Metal Matrix Composites, to great depths and accuracy. The machine itself is designed for high accuracy, control and performance. There is a five-axis gantry manipulator and a 360° rotary table which is continuous or indexing. All axes are CNC programmable. The processing axes are 1.8m (72”) in x and y axes and 1m (39”) in the z axis.
Some of the materials and complex geometries, demostrating the waterjet capability, are presented in the following:
