Verfahren und Vorrichtung zum Bearbeiten von Werkstuecken mit Hochenergiestrahlung

DE 19852302 A UPAB: 20000811 NOVELTY - The light radiation for monitoring the process and the reflected measured light are detected using a machining lens. DETAILED DESCRIPTION - Process for machining workpieces (20) with a laser beam (1) comprises focussing the beam from a lens onto a machining site (40), and evaluating light reflected from the workpiece using a detector (11) from a process monitor. Optical measurement on the workpiece surface is carried out in a machining region of the workpiece with a foreign measuring light source (34) utilizing measured light reflected from the machining region. An INDEPENDENT CLAIM is also included for an apparatus for machining workpieces. USE - For welding and cutting metallic workpieces. ADVANTAGE - Process monitoring and further monitoring measurements can be combined.
