Abstract: The sensor includes at least one pressure chamber that is filled with an incompressible fluid, a membrane that forms at least one wall of the pressure chamber, a pressure transducer measuring the pressure within the pressure chamber, and a pressure arm whose first end is secured to a machine tool member at a location at which force and torque are to be measured and whose second end bears on the membrane. By appropriately choosing the number and disposition of pressure chambers, membranes, and pressure arms, output signals from the corresponding pressure transducers are related to selected components of transverse force torque, and axial force of the machine tool member. Various embodiments of the sensor for use with machine tools having a rotating tool and machine tools having a stationary tool are disclosed, and techniques are described in which these embodiments can be used to determine the angle between transverse force exerted on the machine tool member and a stationary axis of the machine tool, to determine the plane of transverse loading of the transverse force, and to compensate the pressure measurements in accordance with the determined plane of transverse loading.

Abstract: Le détecteur comprend au moins une chambre de pression (PC1...PC8) remplie d'un fluide incompressible, une membrane (62...68, 248) qui forme au moins une paroi de la chambre de pression, un transducteur de pression (PT1...PT8, 250) qui mesure la pression régnant à l'intérieur de la chambre de pression, et un bras de pression (74...80, 210...218, 256, 406, 506) dont la première extrémité est fixée à un organe de machine-outil (90, 232, 400, 500) à un endroit où l'on souhaite mesurer la force, le couple et le déplacement; la deuxième extrémité du bras s'appuie sur la membrane. En choisissant de façon appropriée le nombre et la disposition des chambres de pression, membranes et bras de pression, des signaux de sortie des transducteurs de pression correspondants sont rapportés à des composantes sélectionnées de force transversale et de déplacement transversal, de couple et de déplacement angulaire, de force axiale et de déplacement axial de l'organe de la machine-outil. Différents modes de réalisation du détecteur peuvent être utilisés avec des machines-outils ayant un outil rotatif (180) et avec des machines-outils ayant un outil stationnaire (230), et des techniques diverses permettent d'utiliser ces modes de réalisation pour déterminer l'angle entre une force transversale exercée sur l'organe de la machine-outil et un axe stationnaire de la machine-outil, pour déterminer le plan de chargement transversal de la force transversale, et pour compenser les mesures de pression conformément au plan déterminé de chargement transversal.
