Hi So I got this part where an ID is datum A (measured as circle)
then i have an OD (also circle) which i evaluate runout and concentricity on.
The runout deviation of the OD is about 0.01mm but the concentricity deviation is around 0.07mm
How can this be?
Correct me if I'm wrong but i know both runout and concentricity is how an object deviates from a perfect circular shape or position.
so runout basically measures the wobble when rotating to an axis (so circularity and position)
And concentricity is how closely the object and the datums axis are aligned to each other (so circularity isn't involved)
How can the concentricity deviation be so much higher than the runout?
Ty all for the gdpt tips!
