An Experimental Investigation into Torsional Vibration in

Torsional vibration in ball mills can be a serious problem -even leading to failure. In the design of such mills it is therefore important to be able to design them so that such vibration will not be a problem. It is thus desirable to be able to model the torsional vibration of a rotating system which includes a ball mill.

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.
