Hey y'all ... I'm sure this topic has been beat to death here, I just can't find it, so please help a brother out...
People at my job throw around the term ‘concentricity’ all the time when I’m 99.9999% sure they’re really checking simple runout. I see in the machinist handbook that concentricity belongs in the “location” type along with position and symmetry. I know position, I know symmetry, I can’t seem to find a good example of concentricity.
Can anyone describe in very simple terms the difference between concentricity and runout?
Thanks in advance
EDIT: I forgot to mention that I have worked with a prime who has a spec that says any of their drawings that call out concentricity treat it as runout. Period.
