Abstract

L'invention concerne un procédé de commande d'un système de scie murale (10) lors de la réalisation d'une coupe de séparation dans une pièce (24) entre un premier et un second point limite. Le système de scie murale (10) comprend une scie murale (12) comprenant une tête de scie (14), un bras de scie (17) pivotant, une première lame de scie et une seconde lame de scie de plus grande dimension. La coupe de séparation est effectuée en plusieurs coupes principales, les paramètres des coupes principales (diamètre de la lame de scie utilisée, angle de coupe principale) étant fixés avant le lancement d'une séquence de coupes principales. Une fois la réalisation de la coupe de séparation terminée au moyen de la première lame de scie, la réalisation commandée de la coupe de séparation est interrompue par une unité de surveillance et la scie murale (12) est amenée dans une position de parcage par l'unité de surveillance. La position de parcage est sélectionnée de telle sorte que toutes les actions menées lors d'un changement de lame de scie (pivotement du bras de scie jusqu'à un angle de 0°, démontage de la première lame de scie, montage de la seconde lame de scie et pivotement du bras de scie à partir de l'angle de 0°) puissent être exécutées.
