Abstract: A mechanical apparatus maintains and/or cleans support strips of a workpiece support that forms a support plane for supporting workpieces. The mechanical apparatus includes a transport device for moving the workpiece support along a transport axis X and a service device that has a tool for processing the support strips. The service device is movable by means of a mechanical movement unit along a movement axis Y that is arranged at an angle relative to the transport axis X and/or along a movement axis Z that is arranged at an angle relative to the transport axis X and that is different from the movement axis Y, with the movement of the workpiece support along the transport axis X and the movement of the service device along the movement axis Y and/or along the movement axis Z being controllable in a coordinated manner by means of a control unit.

Abstract: For examining a metal sheet processing operation, a method includes scanning a detection beam along a processed metal sheet by causing a relative movement between the detection beam and the processed metal sheet, during the scanning, determining a position of an edge of the metal sheet hole by monitoring the detection beam, determining, from the determined hole edge position, a geometric configuration of the metal sheet hole, performing a comparison of the determined geometric configuration of the metal sheet hole with a corresponding desired hole configuration; and then sending a signal indicating information about the metal sheet processing operation, based upon the comparison.
