Abstract: An arrangement (1) and a method for optical measurement of a thread, in particular for measurement of an internal thread (12) on a sleeve or on a sleeve end of a metal pipe (11), are disclosed. The arrangement (1) comprises at least one optical sensor (5), at least one further optical element that can be adjusted relative to the optical sensor (5) and that is arranged on an optical bench (3) at a determined distance from the sensor along an optical axis (7) and is designed for optically scanning the internal thread (12), as well as means for acquiring and/or storing and/or evaluating the measurement data recorded by the sensor.

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.
