It is adding tolerances of each parts dims tol to check for fit (max/min) into another part within an assy. One of the most important things to know in Mech Eng.

For complex parts, simple tolerance stackups usually show that the part won't work when the worst-case tolerances are considered. One should introduce statistical probability. But who can put numbers to that without making some parts and measuring them? I can't count the number of times a stackup tempted me to chuck the design but all other things told me to keep it. None of those designs have come back to bite me. That doesn't mean that just because I drive over the same bridge everyday that it will never collapse!
Appreciate the replies. So maybe I am asking alittle too much now, but anyone show me a site where I see a small example. Seems to me easier to understand if I can actually see a small example. THANKS MUCH
They make tools that help analyze stackup tolerances.
"Wildfires are dangerous, hard to control, and economically catastrophic."
"Fixed in the next release" should replace "Product First" as the PTC slogan.
