The application is a simple straightforward condition of diameter to diameter.
His position is this:
The callout on his drawing is concentricity (doubled circle symbol) = .008. His inspection shows Total Indicated runout of .010. He claims that this is concentricity.
I have tried to explain the ASTM definition of both, but to no avail.
My position is that in this case, T.I.R. approximates twice the out of concentric condition, and that his T.I.R. result should be divided by two.
Does anyone know of a simple definition for this premise that I can show my customer?
I am obviously not arguing with this guy, but I could use some help on this one.
