    Chatter Myths Pieces Of The Puzzle In Maximized Machining

    Sep 01, 2004 A 1/4-ball end mill is a small tool and holder assembly, which in turn, has a low mass, so it will have a higher natural frequency reading than a one-inch ball end mill assembly. Therefore, it is likely that this 1/4-ball end mill assembly in this machine will want to run much faster of an rpm to stay out of chatter than this machine can give.
