David,
If you don't otherwise get exactly what you need, you might check this site's FAQ. See topics H-5 and H-7 for ways to determine differential and feed constants. You may need to do some trial & error to get the machine data you need.

Basically, all you really need is the differential ratio formula, and I am aware of only two specific machine formula types, shown as A and B in the FAQ H-5 topic.

You already know the index constant if you are cutting spur gears.

Let us know if you have questions.
