I notice that MMC or LMC is always used with mostly position control. Can it used with, say, a run out? Some literature say no. I just can't understand why? Can you explain?
Thank you.


In my experience and the resources I've got say that MMC/LMC cannot be used with runout tolerances. Both circular runout and total runout are surface controls and feature modifiers (MMC/LMC) are not applied to surface controls.
