Surface topography is generated by the cutter marks of ball-end mill. It has been reported that the surface topography is determined by the eccentricity and tilting angle of tool axis and phase difference of cutting edges. However, the surface topography machined practically based on the theoretical cutting conditions is in disagreement with the simulated one. In this paper, influence of acceleration/deceleration and spindle speed deviation on cutter marks array has been investigated by changing the phase difference of cutting edges. From the experimental and simulation results, it is shown that the cutter marks array is changed by acceleration/deceleration of corner tracking motion. This cause is that a decrease in the tool traveling time by the tracking error changes the phase difference of cutting edges. In addition, it is found that a small deviation of the spindle speed to the input command in the NC data bring a big change to the cutter mark array.
