CA 2554189

A method and apparatus for manufacturing wings includes a fixture that holds wing panels for drilling and edge trimming by accurate numerically controlled machine tools using original numerical part definition records, utilizing spatial relationships between key features of detail parts or subassemblies as represented by coordination features machined into the parts and subassemblies, thereby making the parts and subassemblies intrinsically determinant of the dimensions and contour of the wing. Spars are attached to the wing panel using the coordination holes to locate the spars accurately on the panel in accordance with the original engineering design, and in-spar ribs are attached to rib posts on the spar using accurately drilled coordination holes in the ends of the rib and in the rib post. The wing contour is determined by the configuration of the spars and ribs rather than by any conventional hard tooling which determines the wing contour in conventional processes.

Méthode et appareil de fabrication d'ailes. Comprend un bâti qui retient les panneaux d'aile pour le perçage et le rognage par des machines-outils numériques de précision qui utilisent les dossiers numériques de définition des pièces d'origine. Il utilise les relations de représentation spatiale entre des caractéristiques clés de pièces ou de sous-ensembles détaillés et fait que ceux-ci déterminent, de façon intrinsèque, les dimensions et les contours de l'aile. Les longerons sont fixés au panneau d'aile en utilisant les trous de coordination pour situer précisément les longerons sur le panneau, conformément à la conception technique d'origine. Les nervures des longerons sont fixées à des supports de nervures sur le longeron au moyen de trous de coordination percés précisément aux extrémités de la nervure et dans le support de longeron. Le contour de l'aile est formé par la configuration des longerons et des nervures au lieu de l'automatisation fixe conventionnelle qui détermine le contour de l'aile dans les processus conventionnels.
