Abstract
This paper describes the dynamic synchronous accuracy of translational and rotational axes in 5-axis machining centers. 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. The dynamic model mainly consists of a moment of inertia, friction forces, a velocity controller and a position one. As the results of experiment and simulation, it is clarified 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 verified by the developed dynamic model.
