Parallelism question
Parallelism question
(OP)
Hi everyone
I have a tolerance that states "// 0.025/ 100 in to datum A" in milimeters
I'm interpreting that means parallelism within 0.025 mm over a 100 mm diameter area relative to datum A.
Is it correct?
Tanks

RE: Parallelism question
I also wonder what the "in" means after the 100 -- did you mean mm? It would be strange to mix a millimeter tolerance with an inch dimension on the local segment.

RE: Parallelism question
Trying another time:
" //0.025/ 100 "
it's what appears before the reference to datum A. The diameter was an interpretation i made but my initial tought about it was a linear section of 100 mm, but then only appears as i wrote above without anything after the "100".
Tanks for you attention
