I think you just want the formula for gear lead?
Gear lead = [PI x Teeth] / [NDP x Sin(HA)]
I originally thought you didn't have the differential formula and were looking for a way to calculate HA from a known setup:
Sin(HA) = differential ratio / [.101614 x NDP ]
The formula above is true for single start cutter.
Is this what you need to know?
