    Abstract: It is provided a fluid jet cutting system (110, 210), comprising: a multiaxial industrial robot (112, 212) having an end effector (115, 215) to grip a workpiece (114, 214) to be processed, the multiaxial industrial robot (112, 212) configured to selectively move the workpiece within a working envelope defined by a range of motion of the multiaxial industrial robot (112, 212); a tank (122, 222) positioned within the working envelope of the multiaxial industrial robot (112, 212) to enable the workpiece (114, 214) to be submerged under fluid within the tank (122, 222) during a workpiece processing operation; and at least one fluid jet cutting head (118, 119, 218) having an orifice (130) to generate a high pressure fluid jet (132, 232) and a fluid jet outlet (134) from which to discharge the high pressure fluid jet (132, 232), characterized in that the cutting head (118, 119, 218) is located relative to the tank (122, 222) such that, during the workpiece processing operation, the high pressure fluid jet (132, 232) discharges from the fluid jet outlet (134) beneath an upper surface of the fluid within the tank (122, 222), cuts through the workpiece, and dissipates within a region of the fluid in the tank (122, 222), located adjacent a side of the workpiece (114, 214) opposite the cutting head (118, 119, 218).

    Abstract: A valve pin is provided. The valve pin comprises an engagement portion with a tapered surface, the tapered surface including an asymmetrical surface feature. The asymmetrical surface feature is in the form of an indentation, a depression, a notch, a hole, an aperture, or a cavity formed in a side of the valve pin. The valve pin defines a central axis and the asymmetrical surface feature is only symmetric about one plane of symmetry that includes the central axis of the valve pin.

    Abstract: An abrasive slurry delivery system configured to discharge a high pressure mixture of water (30) and abrasives (54, 54′) for further admixture with a flow of high pressure water (30) to generate an abrasive slurry and ultimately an abrasive slurry jet is provided. The delivery system includes a storage chamber (56), a discharge chamber (58) and a shuttle chamber (60) positioned therebetween. The shuttle chamber (60) is configured to intermittently receive abrasives (54) from the storage chamber (56) and intermittently supply the abrasives (54, 54′) mixed with high pressure water (30) to the discharge chamber (58) to be selectively discharged therefrom. High pressure abrasive slurry cutting systems and related methods are also provided.

    Abstract: A waterjet cutting head assembly is provided which includes an orifice unit to generate a high-pressure waterjet, a nozzle body and a nozzle component coupled to the nozzle body with the orifice unit positioned therebetween. The nozzle component may include a waterjet passage, at least one jet alteration passage and at least one environment control passage. The jet alteration passage may intersect with the waterjet passage to enable selective alteration of the waterjet during operation via the introduction of a secondary fluid or application of a vacuum. The environment control passage may include one or more downstream portions aligned relative to the fluid jet passage so that gas passed through the environment control passage during operation is directed to impinge on an exposed surface of a workpiece at or adjacent to a location where the waterjet is cutting the workpiece. Other high-pressure waterjet cutting systems, components and related methods are also provided.
