John,

The light bulb just glimmered a bit! Man, do I feel like a dumb-a$$! I was mixing radius and diameter values. I had a sarge, once, who would have said that's just D...U...M... dumb!

I have the face cutting perfectly and just need to experiment with the bits I have laying around to find a combination of cutter/speed/feed gets me the smoothest possible cut in plexi to keep the hand finishing to a minimum.

Again, thanks for your help and examples that dragged me kicking and screaming toward the light! ;)

When I get stuck hand coding an arc I draw it in cad and find the start, end and offset points then it usually works.

For any plastics you want as big as possible chip to pull the heat out of the material, of course that depends on your cutter size and material size. Also use a dead sharp insert like the razor sharp ones for cutting aluminum.
