Robert, The only helpful advice I can give is to keep the cutter cool.
We used a wash of liquid nitrogen when machining big fiberglas wind tunnel blades. A 3/4" copper tube fed the LN from the top of the dewar to the tool. No pump was necessary, as the LN flowed freely. You need a valve in the tube to stop it from flowing. Don't let it flow when you're not cutting. The operator must protect himself from the cold when handling the tube. For the best, most accurate finish, we used a diamond coated router ball in a high speed head, mounted to the spindle. It would take a few thousandths only. You had to keep the part cool or the composite would melt and smear.
