I’m currently working on an ongoing project that involves inspecting tubes. We would like to inspect geometric tolerances like size, circularity, cylindricity, and runout on both the internal and external surfaces, but it is currently difficult for us to measure data more than a few inches into tube’s interior.
Here are some general specs:
- Length: about 2 feet to 8 feet
- Outside Diameter: about 2 inches to 8 inches
- Thickness: about .25 inches to 1 inch
Does anyone have any ideas for how we could measure these types of tolerances (or at least establish datums on) the inside surfaces of these tubes?
