    摘要: 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.

    摘要: A laser machining system for machining a work-piece includes a laser scanning head, external optical subsystems, and an image acquisition device. The external optical subsystems correspond to optical channels that include a first optical channel and a second optical channel. The laser scanning head controls an optical path so that a laser beam is directed and focused on the work-piece through the first optical channel and the second optical channel at different times. The first optical channel and the second optical channel correspond to respective specific portions of the work-piece to be machined by the laser beam. The image acquisition device is positioned to view the work-piece through the optical path. The image acquisition device acquires via the first optical channel one or more images of the work-piece to determine a displacement of the work-piece with reference to a best optical focus position of the second optical channel.

    摘要: A processing machine includes mirrors and to reflect a beam L oscillated from a laser oscillator to a predetermined surface on which a workpiece is arranged, optical axis operating mechanisms and to position an optical axis of the beam L at a desired target irradiation position by changing directions of the mirrors and, a camera sensor to capture an image of the target irradiation position and its periphery reflected in the mirror, and an error calibration mechanism to detect an error between the target irradiation position instructed to the optical axis operating mechanisms and an actual position of the optical axis of the beam L in the predetermined surface by referring to the image captured by the camera sensor. A correction amount to the optical axis operating mechanisms and is determined based on the error to irradiate the target irradiation position with the beam L during processing.
