In my shop, we often use tighter internal tolerances than what the prints call out. It gives us a buffer if there is any variation or tool wear. If it is outside the internal tolerances but within customer print we will ship. If it is outside customer print, upper management gets the report and the decision is all theirs. I just tell em if it's good or bad.
I have worked at places that proposed having tighter internal tolerances, but haven't seen it implemented. It always seemed like a safe approach to me. Though, I guess in a sense, that is also the purpose of going the SPC route. It's nice that even if your shop has the goal of meeting those tighter tolerances, they still give you the latitude to approve the part if it measures outside the internal tolerances but within the customer print tolerances.
I'm the same as you. I just report what it its. If a part measures out of spec and I have done all I can to confirm the measurements, I reject it and let the review process handle it from there.
