Waterjet technology development for 600-MPa (87-Ksi) operations involves efforts on machining process development, pumps, plumbing, nozzles, and machining systems development. In this paper, data will be presented on cutting with water and abrasive waterjet at these elevated pressures. The effects of waterjet (WJ) and abrasive waterjet (AWJ) parameters on cutting rates of several materials are analyzed. It is observed that the power required for cutting is reduced as the pressure increases. Sheet metal and composites can be cut effectively with waterjets. The quality of the cut surfaces, however, improves by increasing pressure, adding abrasives, and operating at optimal standoff distances.
