摘要： A method for determining measurement points of an adapted measurement path for measuring a measurement object includes determining measurement points of an ideal measurement path. The method includes determining target measurement points of at least one guide path, which differs from the ideal measurement path. The method includes capturing actual measurement points along the at least one guide path using a coordinate measuring device. The method includes determining deviations between the target measurement points and the actual measurement points of the at least one guide path. The method includes determining the measurement points of the adapted measurement path by changing the measurement points of the ideal measurement path based on the deviations.

摘要： In a probe unit having a measuring probe, a signal processing circuit includes: a signal synthesizing portion configured to process an output of a detection element to output a composite signal obtained by synthesizing displacement components of a contact part in three directions perpendicular to one another; and a signal outputting portion configured to output a digital touch signal to the outside of the probe unit when the composite signal satisfies a predetermined threshold condition. The signal outputting portion includes three comparing portions each configured to compare a threshold condition with the composite signal. When the measuring probe measures the object to be measured, the signal outputting portion outputs the digital touch signal corresponding to outputs of the first and second comparing portions. Thus, there can be provided a probe unit and a measuring system that can stably make measurements with high accuracy while keeping high noise resistance.

摘要： A method and an arrangement for increasing the throughput in a workpiece measurement with a coordinate measuring machine (CMM) is provided. The CMM measures a workpiece, and the measurement is described by at least one measurement parameter, a value of which is variable. The method includes setting an initial value of the at least one measurement parameter, the initial value being a predetermined value of the at least one measurement parameter valid for measuring the workpiece, measuring the workpiece with the initial value, determining a value of at least one predetermined test characteristic based on results of the measuring of the workpiece, determining whether the at least one predetermined test characteristic satisfies a predetermined iteration criterion; and changing the initial value of the at least one measurement parameter and repeating the prior steps upon determining that the at least one test characteristic satisfies the predetermined iteration criterion.

摘要： A positioning apparatus, having first and second members relatively moveable in a substantially vertical degree of freedom. At least one energy conduit is mounted to at least one of the first and second members, which imparts a load on at least one of the members it is mounted to that varies dependent on the relative position of the first and second members. A compensatory member is configured to apply a load that varies, dependent on the relative position of the first and second members, inversely to the variation in load applied by the at least one energy conduit, so as to at least partially counteract the variation in load applied by the at least one energy conduit on said at least one of the members.

摘要： A stylus is arranged on a coordinate measuring machine. A method for aligning a component in relation to the coordinate measuring machine includes positioning the stylus and the component in relation to one another according to a defined arrangement. The method includes acquiring at least one coordinate of the component. The method includes changing at least one of a position and an orientation of the component in relation to the coordinate measuring machine while maintaining the defined arrangement.

摘要： To provide an operation method of a position measuring device capable of accurately and quickly designating a detection point of an object by intuitive operability, such as directly moving the probe with a hand. One aspect of the present invention is an operation method of a position measuring device that includes a measurement head having a probe for designating a detection point of a position of an object, and a moving mechanism for moving the measurement head, and acquires a coordinate of the detection point designated by the probe. The operation method of a position measuring device includes the steps of: using a terminal device including an image acquisition part and a display part to acquire an image of the probe by the image acquisition part and display the image on the display part; detecting a relative positional relation between the probe and the terminal device when having received a movement instruction by the terminal device in a state where an image of the probe is displayed on the display part; and performing a movement control of the measurement head following the movement instruction received by the terminal device by actuating the moving mechanism on the basis of the positional relation.

摘要： Rotating/pivoting sensor system for a coordinate measuring apparatus is provided. The rotating/pivoting sensor system includes a coupling mechanism with which the rotating/pivoting sensor system can be coupled to a measurement head of a coordinate measuring apparatus, a sensor-holding part which is connected directly or indirectly to the coupling mechanism, a sensor which is mounted rotatably about a first rotation axis on the sensor-holding part and which is pivotable about the first rotation axis in a continuous angle range, an angle-measuring system with which a pivoting angle of the sensor can be determined, a fixing device with which the sensor can be fixed in a pivoting position, and a method for adjusting a rotating/pivoting sensor system in a coordinate measuring apparatus.
