摘要： A method of operating an articulated arm CMM is provided. One or more coordinates on an object can be measured with the articulated arm CMM. At least one of the encoders can then be at least partially powered-off. The encoder can then be powered on and one or more coordinates on the same object can be measured without recalibrating the encoder.

摘要： The present invention discloses a quasi-zero-stiffness (QZS) based six-degree-of-freedom (6-DOF) absolute displacement and attitude measurement device. A lower end coil and an upper end coil are respectively charged with currents in the opposite directions; The electromagnetic field and the magnetic fields of an upper magnet and a lower magnet per se are mutually acted to produce an electromagnetic stiffness opposite to the stiffness of a spring. The stiffness of the whole leg is close to zero stiffness. When the to-be-measured platform generates space motion, the reference platform is in the stationary state. At this point, the deformation amounts of the six legs can be measured by laser displacement sensors. The six deformation amounts are respectively inputted into the displacement and attitude resolver, and by forward kinematic solution of the 6-DOF device, the displacement and the attitude of the to-be-measured platform can be obtained.

摘要： An articulated arm coordinate measurement machine is provided with a configurable arm bus. The arm bus being comprised of a plurality of busses that may be selectively coupled to form one or more logical data communications busses. The logical busses may be configured to allow accessory devices to be coupled to the arm and transmit data at higher speeds and at lower costs than may be possible using data busses having fixed communications protocols. In one embodiment, one or more communications switches may be arranged in the probe end of the arm to selectively combine the busses into a logical bus.

摘要： Some embodiments of the invention relate to a location determination apparatus for determining a location of two components relative to one another. The apparatus may comprise at least one location encoder having a read head in cooperation with a code for generating first position determination data at a first measurement frequency. According to some embodiments of the invention, at least one inertial measurement unit is arranged for additionally determining translational and/or rotational accelerations of at least one of the two components and, moreover, for generating second position determination data with respect to the location at a second measurement rate.

摘要： A coupled state versus a decoupled state of a part relative to a machine, in particular of a coordinate measuring device or a machine tool, is determined. The part to be coupled can be moved toward a contact region of the machine in an axial direction in order to establish the coupled state, and can be moved away from the contact region in the axial direction in order to establish the decoupled state. A magnetoresistive sensor is used to generate a sensor signal that depends on an axial position of the part and a further sensor signal that depends on a rotational position of the part relative to the machine. The sensor signals are evaluated and the result is used to determine whether the part is coupled to the contact region of the machine and/or whether the part is decoupled from the contact region.
