I'm sure with those router speeds, you'll be able to go faster. We're running a very different type of mill (a HAAS toolroom mill), so take my cutting speed experience with a grain of salt.

Perhaps we do cut too slow, but since the chip looks good and our part tends to vibrate excessively if we push it much faster, I'm inclined to stick with what we have now.

A HAAS TM should be able to go faster.......... we were cutting up to 30IPM on ours in Alum with no problem.

What kind of spindle speeds are you spinning at?
