interference means that the difference between the size of the hole minus the size of the mating shaft is negative.
An interference fit refers to a fit having an interference (including a minimum interference equal to zero). At this point, the tolerance band of the bore is below the tolerance band of the shaft. The size of the hole in each direction minus the size of the mating axis in each direction is an algebraic difference, which when negative is an interference fit.
