The invention relates to an optical element for guiding and forming a laser beam, and to a method for recording beam parameters, particularly in a laser system, comprising a carrier substrate () and a coating (), which is applied to at least one side of the carrier substrate (), and comprising at least one temperature sensor (). The temperature sensor () is comprised of a number of pixels arranged in a matrix, and each respective pixel has at least one temperature-sensitive element (). The at least one temperature-sensitive element () of the pixel is constructed inside the carrier substrate () made of silicon.

Systems and related methods of programming a laser processing device for automated processing of a workpiece including indicating a processing location on a workpiece with a processing location indicator. The processing location is detected with a processing location detector. The scanner optics of the laser processing device are adjusted to a set position corresponding to the detected processing location. A set position of the scanner optics is detected with a processing location evaluator, and a control program corresponding to the detected set position of the scanner optics is generated with the processing location evaluator.

Remote processing of workpieces

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.

Determining the relative positions of the axes of a laser machining beam and a process gas jet

A method and device for determining the length (b) of at least one of two legs (), of a workpiece () bent toward each other at a bending angle (&#x3b2;) requires location of the workpiece () in a defined position. The position of the bending angle vertex (S) and the position of the end (E) of the leg () 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).

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.

Laser cutting machine and method

A resistance measuring device is coupled with a controller for controlling the parameters of the cutting process. The device is connected between the laser cutting head of the machine of an electrically conducting part of the laser cutting head and workpiece, and the amount of the electrical resistance of the medium between the laser cutting head and the workpiece can be determined when cutting electrically conducting workpieces. In this method, the amount of the electrical resistance of the medium between the laser cutting head and the workpiece is determined, and the distance between the cutting head and workpiece is also determined. Depending on the detected values of the electrical resistance and distance, the parameters of the cutting process are controlled to obtain efficient cutting action.
