To explore the effects of the VSS technique on the stability of milling, we show a threedimensional stability diagram at a nominal spindle speed of 22,000 rpm in Figure 8. With VSS, ADOC is always higher than CSS in Figure 7. However, this is different at a nominal spindle speed of 22,000 rpm, where ADOC does not always increase with VSS ...
