Suppression of chatter is still an important measure to increaseproductivity. Spindle speed variation is a known possibility to reduce chattervibrations without changes to the machine tool using the degree-of-freedom ofthe spindle speed. In this paper the new adaptive spindle speed variation(ASSV) method is presented. The ASSV algorithm automatically adapts theamplitude and the frequency of the spindle speed variation due to the currentprocess stability conditions taking into account the machine capability andthe process technology. A simulation model of the milling process is used toanalyze and verify the functionality of the ASSV. With just using a simple P-or PI-controller in combination with the ASSV algorithm the depth of cut andthus the productivity can be increased to 150% in comparison to cutting withconstant spindle speed with respect to the displacement of the tool tip.
