4th axis gear cutting question

I am nearly finished with my ballscrew conversion, but a question has been
nagging me....I want to do some gear cutting projects as a first real
project on the cnc setup, and with little real machining background
experience, am wondering whether this is a viable project. What I want to
do specifically is cut a set of change gears for my South Bend toolroom
lathe to permit cutting metric threads.
I located a web based utility that permits entering gear pitch information
and it spits out a really cool dxf you can save to the hard drive and finish
tailoring to suit your thickness and other particular 3d info before running
in a cam app (VisualMill in my case). But is this a reasonable project for
my full size cnc setup and what cutters should be used?
Also is this a reasonable job to do using only 3 axes? I don;t ahve the
rotary table converted just yet.

thanks as always for any insight.
