Runout Vs. Total Runout: What is the Core Difference?

WebAug 18, 2003 · Using a TIR methodology to verify a concentricity specification is technically incorrect based on the standard interpretations. Yet, I see it done this way time and time again and parts that pass this check seem to work just fine in their intended application. This tells me that runout, and not concentricity, was probably the specification that ... WebAlthough position will control the "concentric" idea, it is not measured in TIR. (TIR also feels error in shape, as well as alignment.) So maybe that's not enough to represent the original note. So, you need to determine the original intent of the note: to control center-to-center alignment (even if they are oval shaped)? Or to control shape only?
