Metrology Applications

    X-ray CT (computed tomography) can non-destructively scan the entire volume of various machined, printed, or assembled parts in 3D, allowing analysis of external shape, internal shape, and defects such as voids, cracks, and inclusion.

    Notes in dimensional analysis techniques

    Dimensional analysis of cast, machined, or 3D printed parts is an essential process of process control, failure analysis, and research and development. There are mainly three techniques to measure the dimensions of complicated shapes:

    Each technique has its pros and cons. A CMM is considered the most accurate, but it can measure only selected points on a surface. An optical scanner can measure the entire surface but cannot see any internal structure. An X‑ray CT scanner can scan the entire volume, including the internal dimensions and defects, but the sample size is rather limited compared to the other two techniques.

    All three techniques listed above, including X‑ray CT, can analyze parts dimensions, such as the size of parts, diameter of a hole or cylinder, etc. You can also define XYZ coordinate and apply full GD&T analysis to test tolerances of various measurements.
