  • this also applies as far as the geometry of the milling tool 10 itself and / or its constant or alternately reversing running direction is concerned.

Abstract

L'invention concerne un procédé d'usinage partiel ou total d'une cavité quelconque (24) dans une pièce brute au moyen d'une fraise (10), caractérisé en ce que la fraise (10) est déplacée pendant un mouvement de pénétration dans le matériau de la pièce brute et/ou pendant un usinage par enlèvement de matière de la pièce brute, sur une trajectoire de guidage (12) avec au moins un segment de trajectoire tridimensionnel en spirale (14, 14-1, 14-2, 14-3, 14-4, 14-5, 14-6, 4-7, 14-8, 14-9), de forme conique ou sensiblement conique, jusqu'à un point final (18, 18-1, 18-2, 18-3) du ou des segments de trajectoire (14, 14-1, 14-2, 14-3, 14-4, 14-5, 14-6, 14-7, 14-8, 14-9), qui coïncident avec un point de destination (20) d'un renfoncement (22) à l'intérieur de la cavité quelconque (24) ou avec un point de départ (16-1, 16-2, 16-3) d'un segment de trajectoire suivant (14-2, 14-4, 14-5, 14-6, 14-7, 14-9).
