    • In a method for cutting structural components to be joined by laser radiation that is guided by a computer-controlled manipulation system provided with a nominal path for each structural component corresponding to a joining line that is curved as a result of at least one of the structural components being three-dimensionally shaped, the structural component surfaces of the structural components including the joining line are determined measuring technologically. Based on measuring results, the nominal path corresponding to a penetration line of the structural components to be joined is calculated. A marking is formed on a first one of the structural component surfaces. When performing the cut on the structural component surface provided with the marking, the resulting cutting gap and the marking are determining measuring technologically. When a deviation of the cutting gap from the nominal path is detected, the manipulation system is controlled to correct the deviation.

    • The present invention relates to a method for measuring phase boundaries of a material during the machining of a workpiece (12) with a machining beam, more preferably with a laser beam, and a device that is embodied in such a way as to carry out the method. According to said method, during the machining, a machining region (13) containing the impact point of the machining beam (1) on the workpiece (12) is illuminated at least approximately coaxially to the machining beam (1) by means of additional optical radiation (2). Radiation (3) reflected by the machining region (13) is detected, parallel to an incidence direction of the optical radiation (2) or at small angle thereto, by means of an optical detector with local resolution, in order to obtain an optical reflection pattern of the machining region (13). From the optical reflection pattern, a course of at least one liquid/solid phase boundary in the machining region (13) is then determined in an automated manner by means of an image processing algorithm on the basis of a transition from an area containing a large-surface homogeneous area and an area containing a plurality of small-surface homogeneous areas in the optical reflection pattern.

    • A process for treating workpieces by means of laser radiation, particularlyor the cutting, hole burning and material removal with respect to metallic workpieces, in which the treated site of the workpiece is monitored by a radiation detector which contributes to reducing the intensity of the laser radiation when an upper limit value is reached and to increasing it when a lower limit value is reached. In order to achieve a controlled process without exceeding a critical temperature, such as the evaporation temperature, in a simple manner, the process is carried out such that, by the radiation detector, the heat radiation is measured which emanates from its treatment site, by which an upper temperature is monitored as the upper limit value of a predetermined temperature range and a lower temperature is monitored as the lower limit value of this temperature range, and in that the laser radiation, when the upper limit value is reached, is switched off and is switched on again when the lower limit value is reached.
