The process machine interactions in the flycutting machining are presented by integrating the state-space method and finite element method. The prediction of the cutting force fluctuations in the machining process caused by the compliance of machine tool structure is achieved. Furthermore, the relationship between the dynamic performance of the machine tool structure and the machining speed is discussed, which has great influence on the root mean square of waviness and flatness on the machined surface. The simulation results are validated by experiments.
