    • A method for controlling a height of a cutting torch, includes loading a workpiece onto a numerical control machine, scanning the workpiece with a scanning device at a plurality of discrete points on an upper surface of the workpiece, measuring an X-, a Y-, and a Z-coordinate for each respective one of the scanned discrete points, where X and Y define a plane substantially parallel to the loaded workpiece and Z represents a distance between the upper surface and the scanning device at a respective discrete point, storing the measured XYZ coordinates from each of the scanned discrete points into a data set, mathematically fitting the stored data set to a smooth surface representative of the upper surface of the loaded workpiece, and cutting the workpiece along a cutting path programmed into the numerical control machine, while controlling the cutting torch height to correspond to the representative smooth surface.
    • 一种用于控制割炬的高度的方法,包括将工件装载到数控机床上,在工件的上表面上的多个离散点处用扫描装置扫描工件,测量X,Y轴, ,以及每个扫描的离散点的Z坐标,其中X和Y限定基本上平行于加载的工件的平面,Z表示在相应的离散点处的上表面和扫描装置之间的距离, 测量从每个扫描离散点的XYZ坐标到数据集,将存储的数据集数学拟合到表示加载工件的上表面的光滑表面,以及沿着被编程到数控机床中的切割路径切割工件, 同时控制割炬高度对应于代表性的光滑表面。

    • Systems and methods NC plasma cut a metal fabric based upon a two-dimensional cutting path. An NC cutting machine (150) is controlled to make a first pass along the cutting path with the laser height measuring device (160) to collect height data (134) from the metal fabric positioned on a bed (100) of the NC cutting machine (150). Positions for starting and stopping a plasma arc of a cutting torch (120) of the NC cutting machine (150) are determined based upon the height data (134). An enhanced NC program (133) is generated based upon the cutting path, the height data (134), and the positions for starting and stopping the plasma arc, to control the NC cutting machine (150) to cut metal of the metal fabric along the cutting path.
    • 系统和方法NC等离子体切割基于二维切割路径的金属织物。 数控切割机(150)被控制成利用激光高度测量装置(160)沿着切割路径进行第一次通过,以从位于NC切割机床(100)上的金属织物收集高度数据(134) (150)。 基于高度数据(134)确定用于启动和停止NC切割机(150)的割炬(120)的等离子体弧的位置。 基于切割路径,高度数据(134)和用于启动和停止等离子弧的位置产生增强的NC程序(133),以控制NC切割机(150)切割金属织物的金属 切割路径。
