Abstract

In the method according to the disclosure for the unloading of a workpiece part from a workpiece, in parallel with processing time, by means of an unloading element, e.g. a vacuum sucker, the workpiece part is cut from an especially plate-form workpiece by means of a laser beam. The movement of the laser beam relative to the workpiece at least along a first movement axis (X) is divided into a movement of the workpiece and a movement of the laser beam. Before executing a final cut, which separates the workpiece part from the workpiece, the workpiece is decelerated until standstill and the final cut is then executed for example, by moving the laser beam. The workpiece part is being unloaded by an unloading element that operates at least partially during cutting of the workpiece. The unloading element operates according to one of three operating options.
