Slower SFM. If you have just a bit of set on the teeth, rather than a
narrow-kerf blade, you can run pretty fast, but since the material is
cooling the teeth, you have to adjust your feed rate to keep the blade and
plastic cool.

If your teeth have any appreciable set, you'll need to cut a few thou.
large, and abrasively clean up the edges.
