Abstract
A method for machining workpieces (6) uses a moving laser beam (4), whereby the laser tool (3) is held at a separation above the workpiece (6) by means of a multi-axis mechanical manipulator (2) with a manipulator hand (8) and moved along a given track in an offset movement. During the machining process an at least partly opposing compensation movement of the laser beam (4) is superimposed on the offset movement. A device is provided for machining workpieces (6) with a moving laser beam (4). The laser tool (3) is held by means of a multi-axis mechanical manipulator (2) and a device for generation of a opposing compensation movement of the laser beam (4) is superimposed on the offset movement.
