Abstract
The present invention discloses a method to calibrate a laser cutting machine without stopping the production. The method is adapted to laser cutting machine which use a conveyor belt to convey the sheets while cutting them with the laser. The method allows to place calibration marks at locations on the sheet that are convenient according to the production job, thereby minimising the waste of material.
Claims14
A characterization method, for characterizing a laser processing machine having a working area and a laser system configured to direct a laser beam in any location of the working area to process a medium, the characterization method comprising:
- moving the medium along a height of the working area using a conveyor system of the laser processing machine;
- processing a set of marks on the medium with the laser system of the machine according to a set of nominal locations in the working area;
- synchronizing the conveyor system with a location of the laser beam location to spread the marks the medium, wherein each mark can be respectively associated with a processing location in the working area where the mark was processed;
- and
- recording each individual mark on the medium using a camera.
