I am currently designing a mechanical tensile testing setup to operate at different temperatures (-20 to 100 C) in a wet environment. I plan on machining two sets, one from stainless and one from PMMA. Of course, this setup will have a clamp setup similar to the below picture.
When I tolerance the drawing prior to machining, I would probably want to tolerance both of the threaded shafts and all four of the smooth bolts for a sliding fit. How can I (or should I even try to) assess the need to consider the various temperatures when tolerancing these parts?
