Title
(EN) METHOD FOR COLLISION AVOIDANCE AND LASER MACHINING TOOL
(FR) PROCÉDÉ D'ÉVITEMENT DE COLLISION ET OUTIL D'USINAGE LASER
Abstract
(EN)
The invention relates to a method for collision avoidance of a laser machining head (102) in a machining space (106) of a laser machining tool (100), having the steps of: - Monitoring a workpiece (112) in the machining space (106) with at least one optical sensor; - Capturing images of the workpiece (112); - Detecting a change in an image of the workpiece (112); - Recognising whether the change comprises an object standing upright relative to the workpiece (112); - Checking for a collision between the upright object and the laser machining head (102) based on a predetermined cutting plan and/or the current position (1016) of the laser machining head; - Controlling the drives for moving the laser machining head (102) for collision avoidance in case of recognised risk of collision.

L'invention concerne un procédé d'évitement de collision d'une tête d'usinage laser (102) dans un espace d'usinage (106) d'un outil d'usinage laser (100), qui comprend les étapes consistant à : surveiller une pièce à usiner (112) dans l'espace d'usinage (106) à l'aide d'au moins un capteur optique; capturer des images de la pièce à usiner (112); détecter un changement dans une image de la pièce à usiner (112); reconnaître si le changement comprend un objet vertical par rapport à la pièce à usiner (112); vérifier la possibilité d'une collision entre l'objet vertical et la tête d'usinage laser (102) sur la base d'un plan de coupe prédéfini et/ou de la position actuelle (1016) de la tête d'usinage laser; commander les organes d'entraînement pour déplacer la tête d'usinage laser (102) afin d'éviter une collision en cas de risque reconnu de collision.
