Does it make sense to make a tolerance that does not exist in the tolerance tables ?
Does it make sense to make a tolerance that does not exist in the tolerance tables ?
(OP)
Hi All
I am trying to use the tolerance standards more appropriately and with more sense, but regarding to the work we do , that is for the different machines that we have , we happen very often to be obliged to replace a broken piece. for example I see that sometimes tolerances like -+0.01 are chosen , that for fit and precise running, I did not find any, but it seems that they do that by experience or feeling ?! is there any way to reason that if such a tight tolerance is not ok and for example a H7/g6 is a better one?

Certainly on any interference fit, the insertion forces, induced stress in the mated parts, different material properties and other factors may work against simply using the standard limit & fit tables without any extra thought.
In theory using the standard fits should conform to available tooling, ground shafts, mating parts... but varies in practice.
