Hi everyone!
I have a question regarding tolerancing - don't know if this is the right place for it, but here goes:
I have a drawing of a cast part with a flat base. this base has a flatness of 0.5mm applied, and is a datum face: A
In the middle of the part is a boss with a shoulder. This shoulder has a parallelism tolerance on it: "0.2mm //" to datum A.
Question: is this a contradiction? if A is allowed to be 0.5mm out of flat, can we still specifiy the "0.2mm // A" for the shoulder? I can't make my mind up.
Can someone help?
