What is a 3D wall thickness measurement suitable for?

X-ray tomography utilises the ability of X-rays to penetrate objects. Mathematical methods can be used to calculate a volume model from the radiographic images in different rotational positions, which fully describes the geometry and material distribution of the workpiece. For materials that are easy to penetrate, such as plastic, this measuring method is increasingly becoming a prerequisite for manufacturers to remain competitive. One prerequisite for this was the development of the Werth TomoScope® XS family based on low-cost and low-maintenance X-ray sources.

The wall thickness can be analysed on any CT point cloud using the "3D wall thickness measurement" software procedure. As a result, you receive the minimum and maximum wall thickness as well as the average value for the selected area. An automatic colour-coded display of the deviations from the target wall thickness is also possible. On the bottle in the image above, you can clearly see that the wall is too thick at the constriction marked in red and too thin in the lower part marked in purple. The 3D wall thickness of the entire workpiece can be determined with just one calculation process. When evaluating 2D cutting contours (left), the opposing points are connected by colour-coded spines.
