REAL-TIME MONITORING DEVICE FOR LASER NEAR-NET SHAPE MANUFACTURING, AND MANUFACTURING APPARATUS AND METHOD

摘要

Disclosed are a real-time monitoring device for laser near-net shape manufacturing, and a manufacturing apparatus and method. In the design of the monitoring device, an annular monitoring motion platform (200) and a 360° rotary machining table (15), which are coaxially arranged, are provided; a molten pool morphology monitoring portion and a workpiece three-dimensional profile monitoring portion are arranged beside a laser machining head (7) and maintain a synchronous motion therewith; a laser ultrasonic monitoring portion, a molten pool temperature distribution monitoring portion, a stress-strain monitoring portion (100) and a laser-induced breakdown spectroscopy monitoring portion (300) are carried on the annular monitoring motion platform (200); and a CT defect monitoring portion is carried beside the annular monitoring motion platform (200). The components cooperate with each other to achieve omnidirectional, real-time and online monitoring of parameters of a workpiece in a laser near-net shape manufacturing process. The monitoring device has the advantages of simple structure, convenient operation, high applicability, etc.
