  • Patent number: 9844890
    Abstract: High-pressure fluid jet systems are provided which include a pump to selectively provide a source of high-pressure fluid, a cutting head assembly configured to receive the high-pressure fluid and generate a high-pressure fluid jet for processing workpieces or work surfaces, and a fluid distribution system in fluid communication with the pump and the cutting head assembly to route the high-pressure fluid from the pump to the cutting head assembly. The pump, the cutting head assembly and/or the fluid distribution system include at least one fluid distribution component having a unitary body formed from an additive manufacturing or casting process with an internal passage having at least a curvilinear portion to efficiently route matter through the fluid jet system. Example fluid distribution components include fittings, valve bodies, cutting head bodies and nozzles of the high-pressure fluid jet systems.

  • Patent number: 9636798
    Abstract: Systems and related methods are provided for maintaining a spatial relationship between a tool of the multi-axis machine (e.g., fluid jet nozzle of a fluid jet cutting machine) and a workpiece to be processed by the tool. An example system includes a contour follower apparatus having a sensor and a gimbal assembly operable with the sensor to sense a deviation between a machine focal point and a gimbal assembly focal point defined by the gimbal assembly as the gimbal assembly rides upon the surface of the workpiece during operation. The system may further include a gimbal mount assembly configured to sense a collision event of the gimbal assembly with another object.

  • Patent number: 9597772
    Abstract: Methods, systems, and techniques for automatically determining jet orientation parameters to correct for potential deviations in three dimensional part cutting are provided. Example embodiments provide an Adaptive Vector Control System (AVCS), which automatically determines speeds and orientation parameters of a cutting jet to attempt to insure that a part will be cut within prescribed tolerances where possible. In one embodiment, the AVCS determines the tilt and swivel of a cutting head by mathematical predictive models that examine the cutting front for each of “m” hypothetical layers in a desired part, to better predict whether the part will be within tolerances, and to determine what corrective angles are needed to correct for deviations due to drag, radial deflection, and/or taper.

  • Patent number: 9003936
    Abstract: A cutting head of a waterjet cutting system is provided having an environment control device and a measurement device. The environment control device is positioned to act on a surface of a workpiece at least during a measurement operation to establish a measurement area on the surface of the workpiece substantially unobstructed by fluid. The measurement device is positioned to selectively obtain information from within the measurement area indicative of a position of the cutting head relative to the workpiece. A control system is further provided and operable to position the cutting head relative to the workpiece at a standoff distance based at least in part on the information indicative of the position of the cutting head relative to the workpiece obtained by the measurement device. A method of operating a waterjet cutting system is also provided.

  • Patent number: 8894468
    Abstract: A jet receiving receptacle is provided which is coupleable to a high pressure fluid jet system opposite a nozzle thereof to receive a fluid jet discharged from the nozzle after it acts on a workpiece.

The jet receiving receptacle may further include a drive mechanism adapted to rotate the inlet feed component about the central axis such that impact of the fluid jet with the inlet feed component is distributed around the jet receiving surface. The drive mechanism may rotate the inlet feed component continuously or intermittently. Fluid jet cutting systems incorporating a jet receiving receptacle and related methods are also provided.
