    1. Machining head for a laser machining device

      Machining head for a laser machining device

      The invention relates to a machining head for a laser machining device, which is equipped for machining a workpiece (24) using laser radiation (30). The laser machining head comprises an adjustable focusing optical unit (34), which focuses the laser radiation (30) in a focal spot (22). The distance between the focal spot (22) and a machining head can be modified by modifying the focal length of the focusing optical unit (34). A scanning apparatus (44) deflects the laser radiation (30) in different directions. An optical coherence tomography device (48) measures a distance between the treatment head and the workpiece (24 ...

    2. Method for measuring the distance between a workpiece and a machining head of a laser machining apparatus

      Method for measuring the distance between a workpiece and a machining head of a laser machining apparatus

      According to a method for measuring the distance between a workpiece and a machining head of a laser machining apparatus, a machining head is provided, which has a housing that has an interior and an opening for emergence of the laser radiation from the machining head. The laser radiation is directed on to the workpiece, after it has passed through the interior and the opening. An object beam is directed on to the workpiece by a light source of an optical coherence tomograph in such a manner that the object beam passes through the interior and the opening before being ...

      Machining device and method for machining material

      The invention relates to a machining device (10) comprising at least one machining head (16) designed to provide at least one high-energy machining beam (22), especially an electron or laser beam. Such a machining device is used to remove material from workpieces (28) or for connecting workpieces (28) by bonding, especially by means of welding. According to the invention, at least one scanning device (32) designed as an optical coherence tomograph and provided for surface scanning is associated with the machining head (16). The invention also relates to a method for machining material using a high-energy machining beam for scanning ...
