I want to measure gage R&R on the center deflection of composite tubes. The gage is pretty simple. It supports the tube on both ends and then a fixed weight deflects the center. The gage measures the deflection in mm with a digital indicator.
Can I pick tubes that are designed with different stiffness values and test together in a gage R&R? All tubes have the same tolerance spec for deflection but some will be stiff (low deflection) and some will be soft (high deflection).
This would be like measuring OD with calipers, but measuring parts in the gage R&R that have different spec OD's (some small and some large).
The reason that I ask this question is that only using 1 design won't test the entire range of the gage.....plus I don't have 10 tubes of the same design.
Thanks for your input.
