Aggressive material removal is not recommended when machining clamps to size. Suggested machining practice is to spiral down with a .500" end mill by conventional milling 0.020" off the desired clamp diameter at 400 SFPM and .001" per flute and .02 depth per trip around. Finish final diameter at 700 SFPM using same .001" per flute feed and .250" depth and climb mill.

Using these parameters it's going to take over 10 hours per clamp and I have to do a dozen of them... Anyone have any real world reccomendations?
