    • In order to improve manufacturing of an aircraft, a drilling method is provided that allows drilling in confined spaces with less effort. The idea is to use two independent data sources for reducing the tolerances between a component (12) to be joined to a workpiece (10). The component (12) is measured at the supplier using photogrammetry or laser scanning. First geometric data (G1) of the component (12) obtained by this measurement are put in a data storage (20), such as a barcode tag (22) or database. At the manufacturer, the first geometric data (G1) are used to position the component (12) relative to the workpiece (10). Subsequently, the component (12) is measured with a measuring device (30) to obtain second geometric data (G2) that are indicative of the positions and diameters of the joining holes (16) of the component. After determining a deviation between the first (G1) and second (G2) geometric data to be smaller than a predetermined threshold, the automatic drill is positioned at the correct drilling location and joining holes are drilled with a tool (34) into the workpiece. Finally, the component and the workpiece are joined by fasteners.
