2009-1-17 · The critical speed analysis for nonlinear effects of rotor-bearing system and ball end milling are studied in this paper. The nonlinear cutting force can be calculated by using the Tlusty proposed 3/4 rule for chip thickness. The rotor system is supported by bearings with nonlinear spring effects. The critical speeds obtained from this study are compared with two sets of experimental data to

Abstract. Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter.
