Abstract: The invention relates to a method and an apparatus for the laser machining of workpieces, a laser beam being two-dimensionally positionable with the aid of a laser machining head with respect to a surface of a workpiece and it being intended for the machining of the workpiece to take place with predeterminable contours. According to the object, it is to be possible for the forming of the contours to be realized with high positional accuracy at low cost and with little effort. To achieve this object, the laser beam is correspondingly guided by means of a laser machining head, in which at least one two-dimensionally pivotable scanner mirror is accommodated. The scanner mirror or two scanner mirrors is/are connected to an electronic evaluation and control unit. Before the actual machining, a set-actual value comparison is carried out with respect to the position of the workpiece with at least one predetermined contour with respect to the laser machining head. For this purpose, a light beam of a light source is focused and directed via one or else two scanner mirror(s) onto the surface of the workpiece and deflected along at least one axis by pivoting at least one of the scanner mirrors. The light reflected from the workpiece surface passes via the scanner mirror or mirrors onto an optical detector and is focused onto the latter. Taking into account the respective pivoting angle of the scanner mirror(s), the measuring signals of this optical detector are fed to the electronic evaluation and control unit, so that the deflection of the laser beam can be controlled during the machining in dependence on the actual position of the contour ascertained in this way for the machining.

Abstract: The invention relates to a device for laser beam shaping, and in particular to a device for laser beam surface machining. The device includes at least one stationary beam-shaping mirror and at least one rotary mirror that is rotatably supported about a rotational axis and can be selectively driven for rotation. As viewed in the direction of propagation of the laser beam, the at least one static beam shaping mirror is disposed first, followed by the at least one rotary mirror. A perpendicular to a beam deflecting surface of the rotary mirror is inclined at a particular angle relative to the rotational axis by a tapered disc. The tapered disc is fastened to the side of the rotary mirror remote from the laser beam to provide the desired angle of inclination, and the beam deflecting surface of the rotary mirror may be made smooth. One of the stationary and rotary mirrors is configured so that the resulting outline of the beam on the surface to be treated includes an ellipse.

Abstract: The invention relates to a method for machining workpieces by using laser radiation, wherein the workpieces to be machined are moved during the machining and at least one laser beam is deflected with respect to two axes aligned orthogonally to one another. It is therefore the object of the invention to form large-area machining contours with as high a machining speed and as great an accuracy as possible. In the method in accordance with the invention, a procedure is followed that a laser beam is deflected within a working field with respect to two axes aligned orthogonally to one another. Positional coordinates of the respective machining contour are moreover associated in an electronic evaluation and control unit with virtual machining segments in which the machining is carried out sequentially. The borders of individual machining segments are predetermined so that the maximum spacing of mutually oppositely disposed borders of the respective machining segments does not exceed 50% of the maximum length of the working field for the laser beam in the feed direction of the moved workpiece.
