Since cutting force acts on feed drive and spindle drive systems as force disturbance, feed speed and spindle speed are changed. As the results, cutting force is changed because the depth of cut and cutting speed are changed due to the feed and spindle speed changes. In this study, a coupled simulation method, which considers the dynamic behaviors between feed and spindle drive systems and the cutting force, is developed. Simulation results are compared with the experimental results, and it is confirmed that the vibration of the feed and spindle drive systems due to the cutting force can be simulated by the proposed method. It is also confirmed that the cutting force influenced by the vibrations can be expressed.
