ABSTRACT OF THE DISCLOSURE 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 pres- sure 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 have a rota- ting tool and machine tools having a stationary tool are disc- losed, and techniques are described in which these embodiments can be used to determine the angle between transverse force exer- ted on the machine tool member and a stationary axis of the mach- ine 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.
