Rapid Analysis on Chatter Stability Lobes for High Speed Milling Based on Frequency Response Function

Based on the traditional analytical solution of chatter stability for milling process, a new method for fast constructing chatter stability lobes diagram directly from tool tip's FRF was put forward. The calculation speed has been improved for 2～3 orders of magnitude. The validity and effectiveness of the proposed method was approved by good agreement of the chatter stability lobes diagram with that of traditional simulation results. The machining performances of a machining center with three different tools were evaluated and the corresponding optimized cutting parameters were given.
