Title (EN) MACHINE TOOLS AND METHODS OF OPERATION THEREOF
(FR) MACHINES-OUTILS ET LEURS PROCÉDÉS DE FONCTIONNEMENT
Abstract:
(EN) A machine tool (40) comprises first and second support arms (44,46), and a rigid structure (42) which couples the first support arm to the second support arm. A first rotary drive (50) is operable to rotate the first support arm and the rigid structure relative to each other about a first rotational reference axis (53), and a second rotary drive (52) is operable to rotate the second support arm and the rigid structure relative to each other about a second rotational reference axis (55), wherein the first and second rotational reference axes are parallel and spaced apart by a fixed distance. A control arrangement (47) is configured to control the first and second rotary drives such that a workpiece mount carried by the second support arm follows a predetermined path relative to a tool mount carried by the first support arm in a plane perpendicular to the rotational reference axes.
(FR) L'invention concerne une machine-outil (40) comprenant des premier et second bras de support (44, 46), et une structure rigide (42) qui accouple le premier bras de support au second bras de support. Un premier entraînement rotatif (50) sert à faire tourner le premier bras de support et la structure rigide l'un par rapport à l'autre autour d'un premier axe de référence de rotation (53), et un second entraînement rotatif (52) sert à faire tourner le second bras de support et la structure rigide l'un par rapport à l'autre autour d'un second axe de référence de rotation (55), les premier et second axes de référence de rotation étant parallèles et espacés d'une distance fixe. Un agencement de commande (47) est configuré pour commander les premier et second entraînements rotatifs de sorte qu'une monture de pièce portée par le second bras de support suive un trajet prédéterminé par rapport à une monture d'outil portée par le premier bras de support dans un plan perpendiculaire aux axes de référence de rotation.
