Method for linking information with a workpiece data record, and flatbed machine tool

A method for linking information with a workpiece data record of a workpiece in an arrangement of workpieces located in a support plane of a sorting table, the workpieces having been produced from a planar material by a flatbed machine tool in accordance with a processing plan stored in a control unit of the flatbed machine tool, the processing plan comprising workpiece data records, in which relative positions and contours of the workpieces in the arrangement of workpieces are stored, the method comprising:

• registering a selection time relating to a first action of a user that has a spatial relationship with a workpiece to be selected,
• determining a position of a hand of the user in a space above the arrangement of workpieces at the selection time using a locating system,
• deriving a selection position in the support plane from the determined position of the hand,
• selecting a workpiece data record corresponding to the workpiece to be selected from the workpiece data records by comparing the selection position with the relative positions and the contours of the workpieces in the arrangement 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.
