Title
(EN) METHOD AND DEVICE FOR CORRECTING TOOL POSITION ERRORS IN MACHINE TOOLS
(FR) PROCEDE ET DISPOSITIF DESTINES A CORRIGER DES ERREURS DE POSITION D'OUTIL SUR DES MACHINES OUTILS
Abstract
(EN) A method for correcting tool position errors in machine tools, characterised by: determining the at least partial difference, referred to at least one predetermined degree of freedom, between the true position of the tool and a point on the theoretical geometrical locus which the tool should describe, converting said difference into a correction signal, and using said correction signal to move the tool in accordance with that degree of freedom relative to its support structure, at a response rate at least double that of the machine.
(FR) La présente invention concerne un procédé destiné à corriger des erreurs de position d'outil sur des machines outils. Ce procédé consiste à déterminer au moins la différence partielle, en référence à au moins un degré de liberté prédéterminé, entre la position vraie de l'outil et un point du lieu géométrique théorique qu'il devrait décrire, à convertir cette différence en signal de correction, et à utiliser ce signal de correction dans le but de déplacer l'outil selon ce degré de liberté par rapport à sa structure de support, à une vitesse de réponse au moins du double de celle de la machine.
