I am familiar with the basic concepts of fits and tolerances, and I am aware of the various online calculators for determining them. However, I don't understand how to apply those numbers to my actual CAD design for the parts that I want to fit together. None of the calculators seem to account for the actual manufacturing tolerances of the shop I'm working with (in this case +/- 0.1 mm).
So, to be more specific, let's say I have a shaft and hole and I want to work with a nominal size of 6 mm. I want a "locational clearance" fit between them. The calculators tell me the maximum and minimum hole sizes, etc., but I don't know how to gather from this information what I should make the nominal sizes of the hole and shaft in my CAD model. And how can a calculator tell me that anyway, if it doesn't know what size my manufacturing tolerance is?
Can anybody elucidate?
