TL;DR: In this article, a method and apparatus for manufacturing wing spars is described, which includes a fixture (52) that holds spar webs (45) for drilling and trimming by accurate numerically controlled machine tools.
Abstract: A method and apparatus for manufacturing wing spars (30) is disclosed. The apparatus includes a fixture (52) that holds spar webs (45) for drilling and trimming by accurate numerically controlled machine tools (85). The apparatus also includes a chord tool (95) for positioning a pair of chords (40, 42) on a spar web (45). The method includes the steps of positioning a spar web (45) on the fixture (52), determining the actual posiion of the spar web (45) on the fixture (52) with relation to a fixed known location, normalizing a machine tool (85) in accordance with the determining step, drilling chord locator tool coordination holes in the spar web (45) temporarily mounting the chord tool (95) on the spar web (45) by passing fasteners through the coordination holes and corresponding holes in the spar web (45) supporting upper and lower chords (40, 42) on the chord tool (95), clamping the chords (40, 42) to the spar web (45), and then fastening the chords (40, 42) to the spar web (45) by passing fasteners through corresponding holes thereof.
