Abstract: Determination of the relative positioning of a laser machining beam and a process gas jet on a laser machine tool are accomplished by motion of detections made while moving the machining beam and gas jet in relation to a detection element. In some cases actions of the beam and gas jet themselves are detected, such as by cutting light response and sensor deflection caused by the gas jet. Relative head positions at the time of the deflections are used to calculate misalignment between the laser beam and gas jet.

Abstract: A method and device for determining the length (b) of at least one of two legs (13, 14), of a workpiece (12) bent toward each other at a bending angle (?) requires location of the workpiece (12) in a defined position. The position of the bending angle vertex (S) and the position of the end (E) of the leg (13, 14) to be measured are determined. Based on the position of the bending angle vertex (S) and of the end (E), the length (b) is calculated as the distance between the bending angle vertex (S) and the end (E). The measuring apparatus includes a system serving to determine the position of the bending angle vertex (S), a unit serving to determine the position of the end (E) and an evaluation unit which, based on the position of the bending angle vertex (S) and of the end (E), calculates the length (b) as the distance between the bending angle vertex (S) and the end (E).

Abstract: A method and installation for precision imaging of the geometry of workpieces provides relative movement of a CCD detector (13) and the object workpiece (4) in a guided motion. In the process, the CCD detector (13) images the workpiece (4) segment by segment, and the positions of the CCD detector (13) relative to the workpiece (4) and the positions of the imaged workpiece segments are determined. Prior to functional motion of the CCD detector relative to the workpiece (4) to determine its geometry, a rectilinearity and/or angularity calibration is/are performed and, if necessary, a correction value is defined. In at least one subsequent functional motion of the installation, the correction value is factored in for the determination of the positions of the imaged workpiece segments.

Abstract: A laser cutting method employs at least two sensors which are operative during the cutting operation to monitor process parameters and send signals indicative of the monitored parameters determining parameters of the cutting operation in which are indicative of the status of the penetration of the workpiece. The signals from each of the sensors is evaluated by comparing the sensed parameters in the signals with usability criteria to determine the usability of the signals. The signal which compares most favorably with the usability criteria therefor is transmitted to the controller to modify the parameters for the cutting workpiece. In the absence of a control signal from the evaluation, the controller proceeds with the cutting in accordance with parameters which are then operative in the controller. Generally, the selected signal effects the speed of relative movement between the workpiece and cutting head.
