The following data are given for calculating limits of dimensions and tolerances for a hole: Tolerance unit $$'i'$$ (microns) $$=0.45$$ $${\left( D \right)^{1/3}} + 0.001D.$$ The unit of $$D$$ is $$mm.$$ Diameter step is $$18-30.$$ If the fundamental deviation for hole $$H$$ is zero and $${\rm I}T8 = 26i$$ the maximum and minimum limits of dimension for a $$25{H_8}$$ hole (in $$mm$$) are

A keyway of $$5$$ $$mm$$ depth is to be milled in a shaft of diameter $$60 \pm 0.1\,\,$$ by positioning the shaft in a $$V$$-block of angle $$120deg$$ and setting the tool with reference to the intersection of the face of the $$V$$-block. The error due to shaft tolerance which would be transferred on to the component is
