Title (EN) ADAPTIVE MACHINING AND WELD REPAIR PROCESS
(FR) PROCEDE D'USINAGE ADAPTATIF ET DE REPRISE DE SOUDURE
Abstract:
(EN) The present invention provides an apparatus and method for an adaptive machining and weld repair process useful for repairing airfoils (10), particularly damage to an airfoil leading edge (17) and tip. The process first machines away (21) damaged portions of an airfoil (10). Filler material is then added to the machined area through a process such as laser welding (22). At this point, the actual profile of the welded airfoil is measured (23) using a Coordinate Measuring Machine. This data is then used to generate a 'deformation' profile (24), an airfoil profile that approximates the ideal shape of the airfoil. The airfoil (10) is then machined (26) using the date of the deformation profile to produce that shape. The adaptive technology minimizes the amount of stock on material that needs to be removed by hand. The technique thereby significantly reduces costly manual processing.
(FR) La présente invention concerne un appareil et un procédé d'usinage adaptatif et de reprise de soudure convenant pour la réparation des voilures (10), notamment pour les détériorations des bords d'attaque (17) et des bouts. Le procédé consiste d'abord à enlever par usinage (21) les parties détériorées d'une voilure (10), puis à faire un apport de matière sur les zones usinées par un traitement tel que le soudage laser (22). On mesure (23) alors le profil réel de la voilure soudée au moyen d'une machine de mesure des coordonnées. On utilise ces données pour produire un profil de déformation (24), un profil de voilure approché de la forme idéale de la voilure. Pour obtenir cette forme, on usine (26) la voilure (10) en utilisant les données du profil de déformation. Cette technique adaptative permet de minimiser la quantité d'enlèvement de matière à faire à la main, ce qui réduit considérablement un traitement manuel coûteux.
