3D Stability Chart and Surface Location Error Diagram for High-Speed Milling Aerospace Aluminum Alloy

The vibrations in milling process include two parts,I.e. Self-excited vibration(chatter) and forced vibration. Stability due to the chatter and surface location error(SLE) induced by the forced vibration are derived by using the temporal finite element analysis(TFEA). Corresponding to the 3D stability charts(SC) and SLE diagrams are constructed. The results show the transition between the autonomous model for turning and the discrete map model of highly interrupted cutting. And it is also shown that the SLE is especially large at those spindle speed,where high depths of cut are achievable without chatter. Thus,the influences of chatter stability and resonance due to the forced vibration should be considered in dynamic optimization of milling system,simultaneously. The results are confirmed experimentally on a high-speed milling center.
