| 摘要 |
A method for machining a workpiece by means of a laser beam, in which material of the workpiece is removed layer-by-layer according to predetermined definitions to produce a workpiece by traversing the exposed workpiece surface in lengths across the entire surface with a laser beam in order to vaporize and/or combust workpiece material. In a first material removal phase, the laser beam is guided relative to the workpiece over the workpiece surface by adjustable mirrors inside the laser tool, more particularly without mechanical control axes being moved to adjust the relative position between the laser tool and the workpiece. In a second material removal phase, the laser beam is guided relative to the workpiece over the workpiece surface by means of one or more control axes of the machine, the focal length being variably adjustable by means of a variable optical unit. |
