CNC machine tools play important role in industries. The dynamic characteristics of the machine tools are the main factor which affected the status of a machine tools. A three‐dimensional model of a five‐axis CNC machine tool was built by using PRO/E. First, the model was imported into ANSYS software in order to analyse the dynamic characteristics of the machine tool; the first six natural frequencies and vibration modes of the machine tool were obtained through modal analysis and harmonic response analysis. The accuracy of the finite element analysis model was verified through the experimental results. Finally, the optimisation suggestions of the machine tool structure were proposed.
