TP of slot on diameter
TP of slot on diameter
(OP)
Hi ,
this is always a problem for me conceptualizing and I decided to finally try and get some help. I get a lot of prints coming through with tabs, slots, punches, etc somewhere along the radius of a circle and then called out with a true position to the circle but with no other refrence to use as a datum for any angle or something. I have no idea how to get a number because it seems like if its along the circle its ok, or is it that the centerline of the slot has to be straight enough to pass through the center of the circle?

Someone forum1103: Drafting Standards, GD&T & Tolerance Analysis may be willing to give a more detailed response, in fact that may be a better place for GD&T interpretation questions.
What is Engineering anyway: FAQ1088-1484: In layman terms, what is "engineering"?

Then, the center plane of the tab must lie within two imaginary planes spaced 0.02 apart (if the tab's at MMC). This 0.02 "tolerance zone" must be perfectly centered around datum axis A.
