Abstract
A method for monitoring cutting processing on a workpiece whereby a part of the workpiece is separated from a remainder of the workpiece along a desired cut contour, wherein, after the cutting processing, the following steps are carried out: irradiating the workpiece with a laser beam at a location within the desired cut contour, detecting radiation generated by an interaction between the laser beam and the workpiece, and evaluating the detected radiation to determine whether, during the cutting processing, the part of the workpiece was completely separated from the remainder of the workpiece. The invention also relates to a laser processing machine for carrying out the method.

A method for monitoring cutting processing on a workpiece whereby a part of the workpiece is separated from a remainder of the workpiece along a desired cut contour, wherein, after the cutting processing, the following steps are carried out:
- irradiating the workpiece with a laser beam at a location within the desired cut contour,
- detecting radiation generated by an interaction between the laser beam and the workpiece, and
- evaluating the detected radiation to determine whether, during the cutting processing, the part of the workpiece was completely separated from the remainder of the workpiece.
A laser processing machine for cutting processing on a workpiece for separating a part of the workpiece from a remainder of the workpiece along a desired cut contour, comprising:
- a laser processing head for radiating a pulsed laser beam or laser beam pulse onto a location within the desired cut contour after the conclusion of the cutting processing,
- a detector unit for detecting radiation generated by an interaction between the laser beam and the workpiece, and
- an evaluation device, which is designed to determine, on the basis of the detected radiation, whether the part of the workpiece was completely separated from the remainder of the workpiece during the cutting processing.
