Title (EN) NC PROGRAM PREPARATION METHOD OF INTERACTIVE NUMERIC CONTROLLER OR AUTOMATIC PROGRAMMING APPARATUS
(FR) PROCEDE DE PREPARATION DE PROGRAMMES DE COMMANDE NUMERIQUE POUR UNITE DE COMMANDE NUMERIQUE INTERACTIVE OU APPAREIL DE PROGRAMMATION AUTOMATIQUE
Abstract:
(EN) This invention relates to a method of preparing an interactive numeric controller program for a 2-spindle 2-turret 4-axis lathe on the basis of the shapes of a product and work which undergoes primary and secondary machining. The point between the primary and secondary machining processes is determined (S1, S2, S3) on the basis of the data of the inputted shape constituent elements of the product and work. This point in the NC program is selected (S4-S10) so that the time necessary for the primary and secondary machining is substantially equal. In this manner the NC program for the 4-axis lathe having high efficiency can be prepared.
(FR) Procédé de préparation d'un programme d'unité de commande numérique interactive pour un tour à deux broches, deux tourelles revolver et quatre axes en fonction des formes d'une pièce à usiner ainsi produite, subissant un usinage principal et un usinage secondaire. Le point entre les processus d'usinage principal et secondaire est déterminé (S1, S2, S3) en fonction des données relatives aux éléments constitutifs de la forme de la pièce à usiner introduits. Ce point dans le programme de commande numérique est sélectionné (S4 - S10) de sorte que le temps nécessaire pour l'usinage principal et l'usinage secondaire soit sensiblement égal. On peut ainsi préparer un programme très efficient pour la commande numérique d'un tour à quatre axes.
