Description

technical field [0001] The invention belongs to the technical field of laser near net shaping, and more specifically relates to a real-time monitoring device, forming equipment and method for laser near net shaping. Background technique [0002] As a new production process, laser near-net forming technology combines numerical control, computer, laser and other new technologies, and realizes the manufacture of three-dimensional metal parts by cladding metal powder particles layer by layer with laser. Compared with the traditional processing method, it has the advantages of less processing steps, short cycle time, many types of materials, and the ability to process parts with complex shapes. It is widely used in industrial manufacturing, biomedical, aerospace and other fields. [0003] Due to the processing characteristics of layer-by-layer laser cladding and rapid melting and solidification of metal powder particles in the laser near net forming process, the workpiece is pron...
