I look for engineers to ask a question (casting, forge or mechanical production).

How do you assign dimensional tolerances (for example 80 +0.5/-0.3)? What do you use for this work?

 

Who is involved - designer or technologist?

 

Do you make drawings or use only electronic 3d models?

I am not exactly sure what information you are looking for. Tolarancing is determined by many factors. Often they are contingent on mating part tolerances. Of course in extreme cases it could be required to account for thermal expansion. In these cases programs can be used to determine the amount of expansion and contraction that may occur in that area. Although usually we just use math and, geometric dimensioning and tolarancing.
