I'll write a longer and more detailed post about this when I get a chance, but the two main things you need to do when milling carbon-fiber is; [1] keep it wet, soapy water works best because it stays on the CF longer instead of just running off, or [2] put a layer of tape on both sides before cutting. You can use multiple strips of masking tape if you want, but the best option is to use a large, single piece of mask instead...it is comonly used in painting, where the mask is put on and then a design trimmed out of it.
