Abstract

This disclosure relates to methods for cutting metal workpieces in sheet form with a thickness of at least 2 mm. A laser beam is positioned in a nozzle opening of a cutting gas nozzle configured to cut via the laser beam and a cutting gas so that a beam axis of the laser beam along a direction of propagation of the laser beam is at least a distance of 3 mm from a rear opening wall portion of the nozzle opening. Cutting gas configured for concurrently exiting the nozzle opening with the laser beam is emitted through the nozzle opening at a cutting gas pressure (p) of at most 10 bar.
