CNC turning of gear cutters

That would be a good approach too.  Maybe a gearotic version for the lathe could be generated?  Turning the profiles, you can as easily generate a true involute as a circle I guess.  The reasons I didn't do that were, first, the approximation of using a circular profile are probably less than the inevitable tolerances, and second, for the case of a circular profile only, I am pretty sure you can ignore tip radius compensation as the direction of cut is always a tangent to the tip.  Cutting an involute I'd have had to get to grips with cutter compensation on the lathe which I gather doesn't work too well in Mach?
