    • 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.
    • 提供了用于自动化控制流体射流取向参数的方法和系统。 示例性实施例提供了一种动态水射流控制系统(“DWCS”),以根据速度和其它过程参数来动态地控制射流相对于被切割材料的取向。 取向参数包括例如沿着切割路径的射流的x-y位置以及射流的三维取向参数,例如切割头的间隔补偿值和锥形和引导角。 在一个实施例中,DWCS使用一组预测模型来确定这些取向参数。 DWCS优选地包括运动程序生成器/内核,用户界面,一个或多个可替换的定向和过程模型,以及到流体喷射装置控制器的通信接口。 可选地,DWCS还包括用于设计目标件的CAD模块。 在操作中,运动程序生成器接收来自CAD设计模块和用户界面的输入,以构建运动程序,该运动程序可被转发到控制器并由控制器执行以控制切割过程。 可更换型号为运动程序生成器提供访问用于确定合适的喷射方向和过程参数的数学模型集。 例如,在某些环境中,这些方程用于产生每个命令的x位置,y位置,平台补偿值,引导角和锥角。 DWCS还提供了自身与控制器之间的双向通信。 例如,当将目标件从工件切出时,使用控制器功能来显示正在进行的切割路径。 它们也用于获得切割装置的当前值,例如附接的机械和电气装置的当前状态。
