This paper describes the dynamic synchronous accuracy between the axes of translational and rotational in a 5-axis machining center. The 5-axis machining centers are applied to machining complex shapes, such as trurbine blades and impellers. When the 5-axis machining centers are used to machine complex shapes, the velocity of each axis varies greatly. Therefore, the synchronous accuracy of each axis is an important factor to generate high accuracy shapes. In this study, non-uniform 3-axis synchronous motion was investigated in order to estimate the dynamic synchronous accuracy. A dynamic model of the each axis including a rotary axis was developed, and the synchronous motion was simulated. As the results of experiment and simulation, it is verified the developed model can express the experimental results accurately. In addition, a method that can improve the synchronous accuracy is proposed, and its effectiveness is clarified by the developed dynamic model.
