  • Publication number: 20240284815
    Abstract: Land cultivating systems and methods utilizing high-pressure fluid jet cutting techniques are disclosed. An example system includes a mobile unit, a traveler arrangement operably coupled to the mobile unit to ride on the surface of stubble residues as the mobile unit moves across land to be cultivated, and a fluid jet cutting head supported by the traveler arrangement. The cutting head is configured to selectively discharge a high-pressure fluid jet to make a cut through the stubble residues and underlying soil as the mobile unit moves across the land. A soil opening device is provided to form a furrow in the ground in line with the cut made by the high-pressure fluid jet, and a liquid injector nozzle is provided to discharge fertilizer or other chemical(s) into the soil.

  • Publication number: 20240139910
    Abstract: Disclosed herein are components, systems, and methods of operating an abrasive fluid jet system that recycles and reuses abrasive particles. The systems and methods described enable accurate metering and consistent feeding of wet abrasive particles thereby reducing the time and cost of operations associated with drying the recycled abrasive particles prior to reuse. The system may adjust a ratio of wet abrasive to dry abrasive being provided to a cutting head to form an abrasive fluid jet. Components of the system may overcome challenges associated with clumping and other issues that result in difficulty metering wet abrasive.

  • Patent number: 11745310
    Abstract: Disclosed herein are systems and methods for improving the performance of a fluid jet cutting system by testing and adjusting characteristics of the system based on the effect of the characteristics on forces imparted by the system to a workpiece being cut. Also disclosed are systems and methods for monitoring and validating the performance of fluid jet cutting systems, and for diagnosing such systems. In some cases, the technologies described herein can be used to determine whether components of a fluid jet system require maintenance, or that characteristics of the system require adjustment.

  • Publication number: 20220410347
    Abstract: Disclosed herein are components, systems, and methods for accessing and disassembling components of hazardous articles. A cutting head of a fluid jet system generates a fluid jet that exits an outlet toward a workpiece to be cut by the fluid jet. A shroud of the fluid jet system radially surrounds the outlet, and contains an inert substance through which the fluid jet travels between the outlet and the workpiece. A fluid jet system includes a sensor to capture an acoustic parameter of the impact of a fluid jet with a workpiece, and upon detection of a change in the acoustic parameter, discontinues generation of the fluid jet. A fluid jet system includes a sensor to measure thicknesses of various regions of the workpiece and a processor to select a path to cut the workpiece based on the measured thicknesses.

  • Patent number: 11318581
    Abstract: Fluid jet cutting systems, components and related methods for generating relatively low load abrasive fluid jets that are particularly well suited for cutting fragile, brittle or otherwise sensitive materials are provided. An example method includes supplying fluid at an operating pressure of at least 60,000 psi to an orifice having a circular cross-sectional profile with a diameter that is less than or equal to 0.010 inches to create a fluid jet that leaves a fluid jet cutting head through a jet passageway having a circular cross-sectional profile with a diameter that is less than or equal to 0.015 inches.

  • Patent number: 11292147
    Abstract: Methods of trimming fiber reinforced polymer composite workpieces are provided which use a pure waterjet discharged from a cutting head in liquid phase unladened with solid particles at an operating pressure of at least 60,000 psi and in combination with other cutting parameters to provide a final component profile without delamination, splintering, fraying or unacceptable fiber pullout or fiber fracture.

  • Patent number: 11260503
    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.

  • Patent number: 11045969
    Abstract: A catcher tank assembly is provided for a waterjet cutting machine. The catcher tank assembly includes a catcher tank having a plurality of tank sections detachably coupleable together in a side-by-side manner to collectively define a catcher tank having a desired configuration. The catcher tank assembly further includes a workpiece support system detachably coupleable to an interior cavity of the catcher tank. The workpiece support system may include a plurality of workpiece support modules arrangeable in an array to support a workpiece platform of the waterjet cutting machine. The workpiece platform may be formed, for example, by a series of slats supported transversely to parallel rows of the workpiece support modules. Methods and systems which relate to or include the aforementioned catcher tank assembly are also provided.

  • Patent number: 10744620
    Abstract: Air flow management systems and methods to facilitate the delivery of abrasives to an abrasive fluid jet cutting head are provided which enable the makeup of the discharged abrasive fluid jet to be controlled or manipulated in a particularly advantageous manner. The methods may include continuously or periodically measuring a volumetric flow rate of air (or other abrasive material carrier fluid) moving through an abrasive feed passageway at one or more measurement locations and adjusting the volumetric flow rate of air (or other abrasive material carrier fluid) moving through the abrasive feed passageway based at least in part on said measuring. Systems and methods for diagnosing changes in operational conditions and/or changes in the condition of one or more components of an abrasive fluid jet cutting system are also provided.

  • Patent number: 10589400
    Abstract: A waterjet cutting method is provided which includes directing a waterjet onto a surface of a workpiece that is exposed to the surrounding atmosphere, the interaction of the waterjet with the exposed surface defining a cutting location, and simultaneously directing a gas stream onto the exposed surface of the workpiece at or adjacent the cutting location to maintain a cutting environment at the cutting location that is, apart from the waterjet, substantially devoid of fluid or particulate matter. The method may further include moving a source of the waterjet relative to the workpiece to cut the workpiece along a desired path while continuously directing the gas stream onto the exposed surface of the workpiece at or adjacent the cutting location.
