Ken,
Not too sure if I understand the question correctly but if you are
looking to follow the involute shape whilst the gear is laying flat
ie, face up, then you will have a problem getting into the tooth
space with a cutter.
If you wish to cut them across the face then all you will need is a
formed endmill to the correct profile and a means of indexing.
Some CAM programs like Dolphin have an involute program built in.
I believe Fred is going to offer a paid add on to Vector at a later
date but don't quote me on this.
These are aimed at the wire erosion market where cutter size isn't a
problem.
