摘要:
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 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. In one embodiment the DWCS embedded in the controller and performs a “look-ahead” procedure to automatically control cutting head orientation.

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. In operation, the motion program generator receives input from the CAD design module and the user interface to build a motion program that can be forwarded to and executed by the controller to control the cutting process. The replaceable models provide the motion program generator with access to sets of mathematical models that are used to determine appropriate jet orientation and process parameters. For example, in some environments, these equations are used to generate the x-position, y-position, standoff compensation value, lead angle, and taper angle of each command. The DWCS also provides two way communication between itself and the controller. The controller functions are used, for example, to display the cutting path in progress while the target piece is being cut out of the workpiece. They are also used to obtain current values of the cutting apparatus, such as the current state of attached mechanical and electrical devices.

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.
