Abstract: Methods and systems for automating the control of fluid jet orientation parameters are provided. Example embodiments provide a Dynamic Waterjet Control System (a “DWCS”) to dynamically control the orientation of the jet relative to the material being cut as a function of speed and other process parameters. Orientation parameters include, for example, the x-y position of the jet along the cutting path, as well as three dimensional orientation parameters of the jet, such as standoff compensation values and taper and lead angles of the cutting head. In one embodiment, the DWCS uses a set of predictive models to determine these orientation parameters. The DWCS preferably comprises a motion program generator/kernel, a user interface, one or more replaceable orientation and process models, and a communications interface to a fluid jet apparatus controller. Optionally the DWCS also includes a CAD module for designing the target piece.

Abstract: An apparatus for generating and manipulating a high-pressure fluid jet includes an end effector assembly coupled to a manipulator that imparts motion to the end effector along one or more axes. The end effector assembly includes a cutting head coupled to a source of high-pressure fluid and to a source of abrasive, to generate a high-pressure abrasive fluid jet. A motion assembly is coupled to the cutting head via a clamp positioned around the cutting head. A nozzle body assembly is removably coupled to the cutting head assembly upstream of the orifice. The nozzle body assembly may be separated from the cutting head assembly to allow access to the orifice, without removing the cutting head assembly from the clamp. The clamp has a quick release mechanism, allowing an operator to open the clamp by hand to allow access to the cutting head, and an alignment member is provided on an inner surface of the clamp to accurately locate the cutting head in the clamp.
