    • An articulated arm portable coordinate measurement machine (PCMM) can be calibrated or recalibrated using a coordinate measurement machine (CMM). In one method for PCMM calibration, the CMM can be moved to one position, and the PCMM moved to a contact position where a probe head of the PCMM contacts a probe head of the PCMM. The PCMM and the CMM can be operatively coupled, for example, by a synchronizing cable such that position data from the PCMM and the CMM can be obtained at the contact position. The PCMM can be repositioned one or more times to obtain position data at multiple PCMM positions. The CMM can be repositioned as desired and additional contact position data sets obtained by subsequent positioning and repositioning of the PCMM. Various probe head types such as touch trigger probes, hard probes, and contact probes can be used in the calibration systems and methods.
    • 铰接臂便携式坐标测量机(PCMM)可以使用坐标测量机(CMM)进行校准或重新校准。 在一种用于PCMM校准的方法中,CMM可以移动到一个位置,并且PCMM移动到PCMM的探头与PCMM的探针头接触的接触位置。 PCMM和CMM可以例如通过同步电缆可操作地耦合,使得可以在接触位置处获得来自PCMM和CMM的位置数据。 PCMM可重新定位一次或多次,以获得多个PCMM位置的位置数据。 可以根据需要重新定位CMM,并通过PCMM的后续定位和重新定位获得的附加接触位置数据集。 可以在校准系统和方法中使用各种探头类型,例如触发式探针,硬探头和接触探针。

    • Objects having complex geometries, such as tubular segments with multiple bends, can be measured using a system including a coordinate measurement machine. The system can include multiple supports for the object to reduce error due to sag of an object under its own weight. The supports can include positionable support members formed of metal tape. The system can further include a processor configured to determine one or more support locations for the object based on a set of definition data for the object. With support locations for the object have been determined and supports placed, the object can be measured, and a post-comparison operation can be performed. Where the object differs greatly from the definition data, the support locations can be revised.
    • 可以使用包括坐标测量机的系统来测量具有复杂几何形状的物体,例如具有多个弯曲的管状段。 该系统可以包括用于对象的多个支持以减少由于其自身重量下的对象的下垂而引起的错误。 支撑件可以包括由金属带形成的可定位的支撑构件。 系统还可以包括处理器,其被配置为基于对象的一组定义数据来确定对象的一个​​或多个支持位置。 已经确定了对象的支持位置并支持放置,可以测量对象,并且可以执行后期比较操作。 对象与定义数据的区别很大,可以修改支持位置。
