shaft was manufactured with an English standard hob and the sprocket is
manufactured with a Metric standard hob, as long as both members use the
appropriate profile shift which will assure that the reference diameters of shaft
and internal spline are identical. Also, a simple method for determining the
pressure angle of an existing spline has been presented. The result was com-
pared to the ANSI and ISO table of recommended spline pressure angles
which allowed a mature choice of the closest value.

The final section of the article aids in the selection of a hob cutter for the shaft
and a shaper cutter for the internal spline. For the correct setup of the manu-
facturing machine the calculation of the center distances between work and
tool was presented.
