Dimensional changes after Heat treat
Dimensional changes after Heat treat
(OP)
I am curious how you guys handle the dimensional differences before and after heat treating on your drawings. Do you build in the shrink factor,do you inspect the components before heat treat ,or do you call out a before and after heat treat dimensional specification?????
Thanks in advance...
Thanks in advance...

I am of the same mind set, the finished print should be to finished dimensions.
We have a couple of inspection steps in the route and do produce semi-finished parts, so where you choose to inspect in the process can effect the pass/fail criteria for a part, but not necessarily the assembly.
The "shrink" does not effect Form, fit, or function, and we haven't had any issues over the last few years, but as we try to limit inspection steps and simplify the inspection criteria, this issue came to light.
