Abstract: A method for removing a predetermined amount of material from the inner surface (16, 18, 20, 22) of a circular article (10) which deviates from a true circular configuration. The outer surface (32) of the article (10) is touch probed to determine its true location in space, data are then compared to engineering design data to establish the location of the surface (16, 18, 20, 22) to which material removal is desired. A control computer (70) sends commands to the machine control system, causing the machine to remove the excess material down to the desired dimension. Any deviations from circular are compensated for by moving the article (10) radially relative to the cutting tool as the article (10) moves circumferentially relative to the cutting tool.

Abstract: Blade attachment slots for gas turbine engines are prepared by grinding to a stepped, generally straight sided configuration, semi-finish grinding to an envelope about 0.005 inches (.013cm) to 0.010 inches (.025cm) above the blueprint configuration, and finishing by broaching. This reduces the overall cost of the manufacturing process, permits a more economical use of existing broach machines, and allows greater versatility for short model runs and "just-in-time" production.

Abstract: Procédé pour enlever une quantité prédéterminée de matériau abrasable de la surface interne (16, 18, 20, 22) d'un article (10) dont le profil s'écarte d'une configuration parfaitement circulaire. On sonde par contact la surface externe (32) de l'article (10) afin d'en déterminer l'emplacement vrai dans l'espace, les données étant comparées ensuite aux données d'ingénierie pour délimiter l'emplacement de la surface (16, 18, 20, 22) où il faut procéder à l'enlèvement de matériau. Un ordinateur de commande (70) envoie des ordres à un système de commande de machine, cette dernière effectuant l'enlèvement de matériau excédentaire afin de conférer à l'article les dimensions désirées. Tout écart de la configuration circulaire requise est compensé par le déplacement radial de l'article (10) par rapport à l'outil de coupe, à mesure que l'article (10) avance dans le sens de la circonférence par rapport à l'outil de coupe.
