Method for dimensional measurement with coordinate measuring devices characterized in that a computer tomography sensor is integrated in the coordinate measuring device.
Coordinate measuring device for measuring an object (3, 28, 30, 32) with an X-ray sensor system as first sensor system comprising an X-ray radiation source (10, 42) and at least an X-ray radiation sensor that captures the X-rays (7, 56), as well as a second sensor system, such as a tactile and/or optical sensor system (8, 11;
- 9, 44, 46), which can be positioned in the x, y and/or z direction of the coordinate measuring device relative to the object, where the X-ray sensor system (7, 10, 42, 56) can be positioned in accordance with the second sensor system (8, 11;
- 9, 44, 46) in the coordinate measuring device (10),
- characterized in that the object (28) consists of a core (20, 30) with a first density and an envelope (22, 32) with a second density, the first density is much higher than the second density, the core is measurable with the X-ray sensor system (7, 10, 42, 56), and the envelope with the second sensor system (8, 9, 11, 44, 46).
