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.

Unloading a cut-free workpiece part during machining

This disclosure relates to methods and apparatuses for cutting out a workpiece section along a target path from a plate-shaped workpiece using a laser beam of a laser cutting machine having a first drive for moving the workpiece along a first drive axis, a second drive for moving a laser cutting head along the first drive axis. Target values of the target path of the laser beam are divided into target values for the first drive and for the second drive. Before the laser beam reaches a cutting-out end position of the workpiece section, the target values for the first drive are set to a constant value, so that after braking of the first drive, the cutting out of the workpiece section is only still executed by moving the laser cutting head and the workpiece comes to a stop at latest at the cutting-out end position.

Method for cutting out a section of a workpiece using a laser beam, and an associated laser cutting machine

The invention relates to a machine tool for processing a plate-like workpiece, including a processing tool. The processing tool is movable relative to the workpiece and the workpiece is movable relative to the processing tool along a common movement axis. A control unit selectively actuates the processing tool and the workpiece in such a manner that in a first processing mode both the processing tool and the workpiece are moved along the common movement axis and, in a second processing mode the processing tool alone is moved along the common movement axis. The invention further relates to a method for processing a workpiece of the kind mentioned above, to a method for creating a processing program, and to a computer program product having code for performing all steps of the method for creating the processing program.
