[Ky...] Posted June 17, 2020 Share Posted June 17, 2020 Ok I need a bit of advice. I have a position call out on a slot with MMC. Tight tolerance on width and +/-.2mm tolerance in length. Question is when I report the slot position do I give an X only with the tight tolerance MMC and Y only with the +/-.2 MMC or do I report them in as one using the tight tolerance for MMC. Confused 😕 😕Slot call out in Y.pngSlot call out in X.png Link to comment https://qualityforum.zeiss.com/topic/15456-position-call-out-with-mmc-on-slot/ Share on other sites More sharing options...
[Ri...] Posted June 17, 2020 Share Posted June 17, 2020 You would report them independently with their respective width/length. Typically the long dimension of the slot is clearance.

[Br...] Posted June 18, 2020 Share Posted June 18, 2020 Please sign in to view this quote. It does nothing because it doesn't belong there. An elongated hole like this does not have a cylindrical tolerance zone. In fact it has a boundary at its virtual condition that the surfaces cannot violate. So the boundary has a similar shape to slot. It isn't a cylindrical shape. Before the 2009 standard you were actually required to include the word "BOUNDARY" below the feature control frame.
