摘　　要：This paper presents an approach for determiningthe optimal cutting condition for milling thin-walled ele-ments with complex shapes. The approach is based on theinteraction between the thin-walled detail and its periodicexcitation by tooth passing, taking into account the highintermittency of such a process. The influence of theexcitation frequency on the amplitude of the detail oscil-lation during milling was determined by simulation andexperiments. It was found that the analytical results agreedwith experimental data. The position of the detail when thetooth starts to cut was evaluated through experiments. Theinfluence of this parameter on the processing state is pre-sented herein. The processing stability is investigated andcompared with the proposed approach. Thereafter, spectralanalyses are conducted to determine the contribution of thevibrating frequencies to the detail behavior during processing.This paper presents an approach for determiningthe optimal cutting condition for milling thin-walled ele-ments with complex shapes.
