This paper presents an approach for determining the optimal cutting condition for milling thin-walled elements with complex shapes.The approach is based on the interaction between the thin-walled detail and its periodic excitation by tooth passing,taking into account the high intermittency of such a process.The influence of the excitation frequency on the amplitude of the detail oscillation during milling was determined by simulation and experiments.It was found that the analytical results agreed with experimental data.The position of the detail when the tooth starts to cut was evaluated through experiments.The influence of this parameter on the processing state is presented herein.The processing stability is investigated and compared with the proposed approach.Thereafter,spectral analyses are conducted to determine the contribution of the vibrating frequencies to the detail behavior during processing.
