Abstract: A method for producing a thread on at least one end of at least one metal tube (3) by machining the metal tube (3) in at least one CNC-controlled machine tool (2) comprises an optical measurement of the thread during the thread-cutting process and/or following the thread-cutting process, and the electronic detection and evaluation of the measurement data of the thread profile and/or of a sealing lip (6) of the thread, and the derivation of control commands for controlling the machine tool (2) from the measurement data with use of at least one closed-loop control unit coupled to the machine tool (2). A corresponding thread-cutting facility is also disclosed.
