True position of... length?

Erikir
I have a round slot, 17 mm from edge of radius to edge of radius and 4mm wide.

My drawing says
17 +/- 0.3
|TP|0.5 MMC |A|B|C| (length)
Boundary

4+/- 0.3
|TP|0.2 MMC |A|B|C| (width)
Boundary

How do I report that?

  • You should use the vector of the slot as tolerance zone for the TP. Depending on how the leader lines are connecting to the slot, they also depict the tolerance zone for you to use (at least thats the way it's done in ISO-land). Often these leader lines are connected either parallell or perpendicular to the slot, meaning that the direction of the slot tells you the direction of the tolerance zone. Extra important when there is a TP in one axis (non-Ø tolerance zone).

    Same here in ASME land. Problem is word Boundary under FCF, which controls inside boundary of the slot (profile) but they want it reported as TP. Thats why I reported each end of the slot and not centroid of the slot. See link for Tec-Ease in my post
