Title (EN) INSTRUMENTED TOOLS FOR MONITORING INTERACTION DYNAMICS DURING CONTACT TASK
(FR) OUTILS INSTRUMENTÉS POUR SURVEILLER LA DYNAMIQUE D'INTERACTION PENDANT UNE TÂCHE DE CONTACT
Abstract:
(EN) An instrumented tool for surface finishing of a work-piece, the instrumented tool comprising: a tool configured to be spun and brought into contact with the work-piece while spinning; a spindle configured to provide a spinning torque to spin the tool; a flexible coupler provided between the spindle and the tool to transmit only spinning torque of the spindle to the tool; a rigid connection provided between the spindle and the tool in parallel to the flexible coupler; and a multi-axis force/torque/strain/pressure sensor attached to at least the rigid connection; wherein the rigid connection and the multi-axis force/torque sensor are decoupled from spinning of the spindle and the tool, and wherein the multi-axis force/torque sensor is configured to measure at least one of: contact force and torque between the tool and the work-piece.
(FR) L'invention concerne un outil instrumenté pour la finition de surface d'une pièce à usiner, l'outil instrumenté comprenant : un outil conçu de façon à être mis à tourner et mis en contact avec la pièce à usiner pendant la rotation ; un arbre conçu pour former un couple de rotation pour faire tourner l'outil ; un couplage flexible prévu entre l'arbre et l'outil afin de transmettre seulement un couple de rotation de l'arbre à l'outil ; un raccord rigide situé entre l'arbre et l'outil en parallèle au couplage flexible ; et un capteur de force/couple/contrainte/pression à axes multiples fixé au moins au raccord rigide ; le raccord rigide et le capteur de force/couple à axes multiples étant désaccouplés de la rotation de l'arbre et de l'outil et le capteur de force/couple à axes multiples étant conçu pour mesurer la force de contact et/ou le couple existant entre l'outil et la pièce à usiner.
