Chatter Myths: Pieces of the Puzzle in Maximized Machining
9/1/2004 · A 1/4ball 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 oneinch ball end mill assembly. Therefore, it is likely that this 1/4ball 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.
