It is for helical gears, and is linked to the feed gears. (Also easy
to do with LinuxCNC
The differential gears are nothing to do with prime but to add the
traverse into the equation and also to add a rotation for a helical.
I have a diagram of one at
http://www.collection.archivist.info/hobbing.html
then you can wind the hob back along its cut traverse and it remains "in gear"

It's actually almost trivial with HAL.
