Abstract
A device for monitoring, in particular for closed-loop control, of a thermal cutting process carried out on a workpiece. The device includes a focusing unit for focusing a machining beam, in particular a laser beam, onto the workpiece for the formation of a kerf on the workpiece. The device also includes an image acquisition unit to generate at least one image of a region of the workpiece, and an evaluation unit configured to determine, based on the at least one image, at least one measured variable for the course of the gap width of the kerf in a thickness direction of the workpiece. The invention also relates to an associated method for monitoring, in particular for closed-loop control, of a thermal cutting process carried out on a workpiece.
