Abstract

Disclosed is a method for loading a sheet placement device of a flat bed machine tool with a material sheet, wherein the material sheet is supplied to the machining operation carried out by the flat bed machine tool, starting from a target position assigned to the machining operation in a machine coordinate system, and the flat bed machine tool comprises a camera system having at least one camera. The camera system is designed to produce captured images of the sheet placement device, which are calibrated three-dimensionally in relation to the machine coordinate system of the flat bed machine tool. The method comprises the steps: producing a captured image of the material sheet in the region of the sheet placement device; evaluating the captured image to determine an actual sheet position in the machine coordinate system; measuring a deviation of the determined actual sheet position from the target position; and using the measured deviation to align and position the material sheet.
