Water jet cutting (Hydrodynamic cutting)
...profiling sheet materials. Cutting medium is water with additives to aid coherence of the jet stream, reduce noise and prevent freezing. The jet has a velocity of 5–15 m s-1, a flow rate of up to 75 l min-1 and produces a force of 5–135 N on the workpiece. Pressure of jet varies from 70 to 415 MPa; the greater the pressure, the greater the penetration and quality of...
