Abstract: The invention relates to a method for the cutting processing of a panel-type material in a machine which comprises a processing station in a machine base frame, and the processing station is assigned a loading and unloading station. The panel-type material is laid on a pallet which is movable between the processing station and the loading and unloading station, and the pallet is moved into the processing station for subsequent processing and is positioned on a pallet carrier of the machine base frame for the subsequent processing of the panel-type material, wherein, before the start of the processing process of the panel-type material by the processing unit, the pallet is lifted from the pallet carrier by an air spring device and is positioned in a manner decoupled from the pallet carrier, and after the processing process of the panel-type material, the pallet is coupled to the pallet carrier.

Abstract: 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.
