Vibration-assisted machining (VAM) has the advantage of reducing the cutting forces involved. Analysis of the cutting force of VAM is useful in characterizing the cutting process, since tool wear and surface texture levels depend closely on the cutting force . However, it is difficult to predict the transient cutting force of VAM due to its complicated motion trajectory. The study of chip formation is helpful in predicting the cutting force. The geometric features of chips have important effects on cutting force, and in order to investigate the time-varying cutting force in VAM, a model of the geometric features of chips...
