The apparatus includes a machining laser source for generating a machining laser beam; an illumination laser source having a power for generating an illumination laser beam having a spectral range; an outlet opening for the machining laser beam and the illumination laser beam; and a laser beam guiding device which is designed such that the machining laser beam and the illumination laser beam emerge coaxially through the outlet opening; wherein at least one element selected from the power of the illumination laser source and the spectral range of the illumination laser beam is selected such that the illumination by the illumination laser beam is brighter than a self-emission of the workpiece in a machining region during laser machining. Additionally, a method for laser machining a workpiece is also included in the present disclosure.
The present disclosure relates to a method for creating a robot control program for operating a machine tool, in particular a bending machine, having the steps of generating image material of a machining operation of a workpiece on the machine tool by means of at least one optical sensor; extracting at least one part of the workpiece and/or at least one part of a hand of an operator handling the workpiece from the image material; generating a trajectory and/or a sequence of movement points of at least one part of the workpiece and/or at least one part of a hand of an operator from the extracted image material; and creating a robot control program by reverse transformation of the trajectory and/or the sequence of movement points.
