Abstract
This paper introduced control system for complex curved surface laser shock processing, which was a set of automatic and digital control system operation, and controlled by the industrial PC/PLC. And it completed the real-time online monitoring and information interaction feedback, belonging to the open distributed system, by the fact that the remote monitoring and control system status of processing effectively avoid the occurrence of major accidents. This system was laser shock processing core device (including laser, robot, auxiliary control, quality testing device and auxiliary system, etc.), that implemented each link of information interaction and systems work together. By the remote monitoring, control system status of processing effectively avoided the occurrence of major accidents. At the same time, the control system added process of laser shock processing test data record function. According to actual demand parameters database called the background, parameter optimization was processed effectively. In addition, the system also could realize laser shock processing model established in this paper, complex surface machining trajectory planning automatically and processing strategy. The system can realize the automatic production of the whole blade laser impact of aero engine, and it is already in the engineering application stage.
