A method creates a reference recording of the unloaded state of a workpiece carrier. The method includes: A) creating a recording of the workpiece carrier with a camera; B) determining a loading state of the workpiece carrier by evaluating the recording by an algorithm; and C) storing the recording as a reference recording in a case where the workpiece carrier is determined as being unloaded by the algorithm.

The disclosure provides methods for providing panel planning geometry data for planning a laser cutting process. The methods include producing an image recording of a remaining panel-shaped material, e.g., wherein the remaining panel was processed by a laser flatbed machine and has inner cutout regions, evaluating the image recording to determine a remaining panel outer contour, evaluating the image recording to determine an inner cutout region, wherein the inner cutout region is determined by an inner cutout contour identified in the image recording, deriving a remaining area of the remaining panel using the outer contour and the inner cutout region, wherein a laser cutting process can be based on the remaining area, and outputting panel planning geometry data, which define the geometry of the remaining area. Laser flatbed machines for cutting workpieces out of panel-shaped materials using a laser beam and the methods disclosed herein are also described.

A method determines an actual state of a supporting bar for supporting a plate-like workpiece on a machine tool for a cutting the workpiece. The method includes: determining a geometry of supporting projections on the supporting bar by a light section method, which includes: projecting a longitudinal line of light onto a longitudinal side of the supporting bar; with the line of light, scanning the longitudinal side over a height region assigned to the supporting projections in the direction of the height of the supporting bar, detecting the scanned extent of the longitudinal side of the supporting bar to generate an image of the longitudinal side of the supporting bar, and determining the geometry of the supporting projections based on the generated image; and comparing the determined geometry of the supporting projections with the defined intended geometry of the supporting projections.

A method for linking information with a workpiece data record of a workpiece includes registering a selection time relating to a first action of a user that has a spatial relationship with a workpiece, determining a position of a hand of the user in a space at the selection time using a locating system, deriving a selection position in a support plane from the determined position of the hand, selecting a workpiece data record from the workpiece data records by comparing the selection position with relative positions and contours of the workpieces, registering a second action in which the user carries out a gesture movement, wherein an information item to be logged in a database is assigned to the gesture movement, reading the information item from the database, and linking the information item with the selected workpiece data record.

A method for displaying a sequence of workpiece-illustrations and/or order information for supporting a sorting process during manufacturing of workpieces with a manufacturing system includes transporting manufactured workpieces with the conveyor system to the sorting point according to a sequence and arrangement specified by the processing plan. The method further includes receiving, in the processor of the display unit, workpiece image data and/or order data provided by the machine tool control system for the workpieces transported to the sorting point. The method additionally includes displaying the workpiece image data and/or the order data on the monitor of the display unit in a sequence and/or an arrangement such that the sequence and/or the arrangement of the workpiece image data and/or the order data corresponds to the sequence and/or the arrangement of the workpieces transported from the conveyor system to the sorting point.
