Tolerance hole to have interference fit to shaft, RFS
Tolerance hole to have interference fit to shaft, RFS
(OP)
Hi,
I have been made mechanical drawings most of my life and I guess I am having a brain sneeze (Thanks Si).
Besides just long hand stating it, how would you draft having a bore interference fit a shaft regardless of the shaft diameter. In this case the shaft varies and we do not want to machine it but make the mating hole have an interference fit of .0005/.001". Would like to state in GD&T terms if possible but interested in all responses.
Man I feel dumb asking. Be gentle or not.
Thanks,
Mark

Not the easiest thing to inspect though.

However this may be the best way? I admit something like the above is how I have always done this before. Now however I have a big name customer asking me how to do this and I thought I might be showing my country boy heritage.
Something so simple I may be trying to make it hard, thought about using ISO fits but they really do not address this occurrence.

Measure shaft. Calculate hole limits. Make hole within limits.

In terms of functional requirement arguably you should perhaps specify the min pull out force or some such.

And BTW, if pieces are fitted on individual basis, doesn't it make them "matched pair"?
Just some thoughts.
