摘要：
To improve the synchronization of sapphire multi-wire saw, a new tension and synchronization control method was designed. Based on analyzing the tension principle of sapphire multi-wire saw synchronization control system, the tension dancer design, wire passing design and wire traverse design were optimized. To reduce the shock of emergency traverse direction switch, a flexible direction switch method was proposed. To realize multi-axis synchronization, the virtual main axis was used based on analysis of axis coupling relation and synchronization movement. To avoid the shake of two mail rollers, a master slave roller control method was designed which could make two motors get accurate torque synchronization. The hardware platform and software structure of control system based on Ethercat was designed and realized, and the whole control system was proven by DX4040 sapphire multi-wire saw. © 2019, Editorial Department of CIMS.
