CA 2515459

A cutting tool and track system includes a multi-segment track assembly (14) configured to be removably attached to a surface of a workpiece (50), a carriage assembly (18) configured to ride along the track assembly (14), a carriage drive mechanism (16) arranged to drive the carriage assembly along the track assembly, a cutting tool assembly (12) connected to the carriage assembly (18), and a tool driving system (46) connected to the cutting tool assembly (12). The cutting tool assembly rotatably supports an end mill type cutting tool (24) that may be driven in a radial cutting plane about the axis of a tubular workpiece or along a workpiece surface. A method is provided for cutting a workpiece wherein a cutting tool assembly rotatably supports an end mill mounted for travel along a predetermined transport path in a cutting plane about a central axis of the workpiece wherein the end mill is first fed through the wall thickness of the workpiece and the cutting tool assembly is moved along the transport path in the cutting plane to cut the workpiece.

L'invention a pour objet un outil coupant et un système de tracé comprenant un ensemble de tracé multi-segments, fixé, de manière à pouvoir être détaché, à la surface d'une pièce, un ensemble chariot conçu pour rouler le long de l'ensemble de tracé, un mécanisme de commande d'un chariot permettant de commander ledit ensemble chariot le long de l'ensemble de tracé, un ensemble outil coupant relié à l'ensemble chariot, et un système de commande de l'outil relié à l'ensemble outil coupant. Ledit ensemble outil coupant supporte de manière rotative un outil de type fraise en bout qui peut être commandé dans un plan de coupe radial autour de l'axe d'une pièce tubulaire ou le long de la surface de la pièce. L'invention concerne un procédé pour couper une pièce, un ensemble outil coupant supportant de manière rotative une fraise en bout, conçue pour se déplacer le long d'un chemin de transport prédéterminé dans un plan de coupe autour de l'axe central d'une pièce, ladite fraise en bout étant introduite à travers l'épaisseur de la paroi de la pièce, puis l'ensemble outil coupant est déplacé le long du chemin de transport dans le plan de coupe, ce qui permet de couper la pièce.
