  • Patent number: 11592278
    Abstract: A method is described for determining a relative position of an axis of rotation of a rotary table of a coordinate measuring machine. The rotary table has or forms a reference element that is arranged eccentrically in relation to the axis of rotation. The method includes a measuring step including performing a rotary movement of the rotary table, and producing measuring points that encode a position of the reference element by a sensor of the coordinate measuring machine during the rotary movement. The method includes a determining step including determining the relative position of the axis of rotation of the rotary table based on the measuring points.

  • Patent number: 11060891
    Abstract: A holder is configured to hold multiple reference standards for calibrating a measurement system. The holder includes a first receptacle that is configured to receive a first reference standard. The holder includes a second receptacle that is configured to receive a second reference standard. The holder includes a calibration jig that is configured to facilitate a bijective determination of a position and orientation of the holder in space.

  • Patent number: 10852122
    Abstract: A method and an arrangement for capturing an object by a movable sensor are provided. The method includes moving the sensor relative to the object and repeatedly ascertaining an instantaneous position of the sensor by a position measurement system, outputting the position to an evaluation device at a predetermined time point, repeatedly capturing the object by the sensor during a capturing time interval and outputting a measurement signal corresponding to the information captured during the capturing time interval. For at least one capturing time interval, a point in time of the capturing of the object is determined which lies within the capturing time interval, position values are ascertained and outputted at points in time which include the point in time of the capturing, and a position main value is ascertained based on the position values which approximates the position of the sensor at the point in time of the capturing.
