Hi,
we're facing a problem with a tube part which is approx. 500mm in lenght and consist of multiple diameters.
We have a concentricity on a diameter which is almost in the middle of the tube. Datum is A-C - two diameters - one on each side.
Now the problem is, that with every turn of the tube, concentricity is always different - as told, it shouldnt be.
Example:
Concentricity without moving the tube - 5 measurements - there's no deviation between measurements.
If we turn the tube 4 times for 120° - 1st and 4th measurements are identical.
Tried with different alignments - calculated concentricity is always the same.
Any idea?
BR
