Abstract
The disclosure relates to methods and apparatuses for controlling a cutting process in which a workpiece is cut by a high-energy beam. A process light signal is detected emanating from an interaction region of the high-energy beam with the workpiece in a first wavelength range (Δλ), in which at least one metallic constituent (Fe, Cr) of the workpiece has at least one emission line, and in a second wavelength range (Δλ), which differs from the first wavelength range, in which continuum radiation of the workpiece without emission lines is detectable. Vaporization of the at least one metallic constituent (Fe, Cr) is monitored on the basis of an intensity of the process light signal detected in the first wavelength range (Δλ) and on the basis of an intensity of the process light signal detected in the second wavelength range (Δλ).
