Abstract: Aiming at the problems of too much manual participation and low intelligence in the existing sawing processing systems for honeycomb denitration catalysts, the physical properties and cutting dimensions of honeycomb denitration catalysts were analyzed, and the existing achievements of sawing cutting system for honeycomb denitration catalysts were summarized. A novel high efficiency and intelligent saw cutting system was designed which combines with a 6DOF industrial robot. The saw cutting system can perform a complicated workflow, automatic feeding, robot loading, doubleended synchronous sawing, robot layingoff, and automation ejection. The fuzzy PID control strategy was used to achieve the closedloop control of the constant cutting force while varying the cutting feeding speed, and the Profibus bus was used to exchange the information between the 6DOF industrial robot and the PLC control system. The experiment results indicate that the presented intelligent saw cutting system can work on the situation of unmanned operation, so as to greatly reduce the toxic sawdust damage on the human body, the system also has the remarkable features of high efficiency, high precision and intelligence.
