Abstract
The invention relates to a method for determining a focal position of a machining beam, in particular a laser beam, relative to a workpiece when machining the workpiece using the machining beam, having the following steps: receiving at least one spatially resolved image of a workpiece region to be monitored, said region comprising the cut edges of a cut gap formed during the machining process on the upper face of the workpiece, ascertaining a gap width of the cut gap on the upper face of the workpiece using the cut edges in the at least one spatially resolved image, and determining the focal position of the machining beam relative to the workpiece using the ascertained gap width. The invention also relates to a corresponding device.
