Abstract

This paper investigated the multi-axis synchronous control in a typical CNC system. The necessity of utilizing field bus is identified. In addition, the effect of jitter and skew on CNC system is analysed. A novel set-up scheme for network CNC system and corresponding EtherCNC protocol are proposed. The network topology and frame structure and the principle are introduced in detail. The hardware precision time protocol realization method is proposed. The effect of jitter on position precision controlling was validated with the experimental characterization of the proposed scheme.
