Aiming at the whole leaf disc of aeroengine, a new type of control system of surface laser shock enhancement is developed. This system is a fully automatic and controllable operation system. Through the integrated control of industrial computer / PLC, automation and digital control are realized, and real-time on-line monitoring And interactive feedback, belong to the open distribution system. The system is used in the laser shock enhancement core equipment (including laser, robot, auxiliary control, quality inspection device and auxiliary system, etc.) to realize the information exchange and system cooperation in all aspects. Through the real-time monitoring system, the system can observe the machining status remotely and effectively Avoid major accidents. At the same time, the control system adds the laser shock enhancement process test data recording function, according to the actual needs of the backstage process parameters database, to achieve efficient process parameters optimization. In addition, the system can also realize such functions as laser shock enhancement model establishment, finite element simulation of machining process, automatic planning of complex curved surface machining trajectory and formulation of machining strategy, so as to realize the automated production of laser blade impact hardening of aeroengine blade, which is currently in Engineering application stage.
