A drilling method is provided allowing drilling in confined spaces with less effort. Two independent data sources are used for reducing tolerances between the component to be joined to the workpiece. The component is measured at the supplier using photogrammetry or laser scanning First geometric data of the component obtained by this measurement are put in a data storage, such as a barcode tag or database. At the manufacturer, the first geometric data are used to position the component relative to the workpiece. Subsequently, the component is measured to obtain second geometric data indicative of the positions and diameters of the component joining holes. After determining a deviation between the first and second geometric data to be smaller than a predetermined threshold, the automatic drill is positioned at the correct drilling location and joining holes are drilled into the workpiece. Finally, the component and the workpiece are joined by fasteners.

A method of manufacturing a panel assembly includes supporting the panel assembly in a free state using a holding fixture. The panel assembly has a skin panel, and sacrificial material coupled to a skin panel inner surface. The method includes acquiring a free state outer surface contour of the panel assembly by scanning a skin panel outer surface while the panel assembly is supported by the holding fixture.
