Question

Calculate the fundamental deviation and tolerance and hence the limits of size for the shaft and hole for the following fit 64H₈ –f₇ mm.  The diameter steps are 50 mm and 80 mm. For shaft designation f, upper deviation is assumed as –5.5 D^0.41.

         Data:      For       tolerance

                        H 8      25 i

                        f 7        16i
