Abstract

Procédé de préparation d'un programme d'usinage de rainures cylindriques pour une unité de commande numérique interactive permettant l'usinage d'une rainure sur la surface latérale d'un pièce cylindrique. On fait correspondre la surface latérale sur une périphérie d'une pièce avec un plan (22a) d'un système de coordonnées orthogonales composé d'un axe (C) se développant linéairement par rapport à une broche et d'un axe (Z) dans le sens de la longueur d'un cylindre. Les données requises (2, 3) sont introduites de manière interactive par l'utilisation des valeurs des coordonnées du système de coordonnées orthogonales, de manière à définir la forme de la rainure et à préparer un programme d'usinage. Le programme d'usinage peut ainsi être préparé aisément et de manière interactive dans le système de coordonnées orthogonales bidimensionnel.
