摘要： The invention relates to a device (1) for monitoring, more particularly controlling, a cutting process carried out on a workpiece (3), comprising: a focussing element (4) for focussing a high-energy beam (2), more particularly a laser beam, onto the workpiece (3); an image capture apparatus (9) for scanning a monitoring region of the workpiece (3) that includes a region (18) of interaction between the high-energy beam (2) and the workpiece (3); and an analysis apparatus (19) designed to analyse the scanned region (18) of interaction and work out at least one characteristic variable (α) of the cutting process, more particularly a kerf (16) formed during the cutting process. The image capture apparatus (9) can be designed to form an observation beam (7a) for observing the region (14) of interaction from an observation direction (R1) at an angle (ß) to the beam axis (13) of the high-energy beam (2), and can include an imaging optical system (14) for generating an image of the region (18) of interaction from the observation direction (R1) at an angle (ß) to the beam axis (13) of the high-energy beam (2). Alternatively or additionally the analysis apparatus (19) can be designed to analyse the scanned region (18) of interaction and work out characteristic variable(s) of the cutting process, namely a cutting front angle (α) in the kerf (16) and/or an amount by which the cutting front angle is greater and/or less than a specified cutting front angle (α
G ) in the kerf (16), and the device (1) can comprise a controller (20) for controlling the cutting front angle (α) to achieve a specified constant value (α
G ) by influencing at least one manipulated variable (v, P) of the cutting process. The invention also relates to associated methods.

摘要： The present disclosure relates to a device for monitoring and for controlling a laser cutting process on a workpiece, and a method of using the same. The device includes an image capturing apparatus for capturing an image of a region of the workpiece to be monitored, in which the region of the workpiece to be monitored includes a region of interaction of a laser beam with the workpiece, and an evaluation apparatus for detecting material boundaries of the workpiece using the captured image. The evaluation apparatus is configured to determine at least one characteristic value of the laser cutting process based on a geometric relationship between at least two of the detected material boundaries, the region of interaction, or combinations thereof.
