Abstract

The invention relates to a laser processing system and a laser processing method. The laser processing system comprises a laser generator, a nozzle, an optical unit, an image processing unit, a process model and a control device, wherein the laser generator is used for generating laser to form a weld pool on a substrate; the nozzle can provide a cladding material for the weld pool; the optical unit can acquire images of one or more intrinsic parameters in the processing process; the image processing unit can process the images to acquire the measured values of the intrinsic parameters; the process model is used for setting the target values of the intrinsic parameters, wherein the target value of at least one intrinsic parameter is a variable; an the control device can control controllable parameters in the processing process based on the comparison between the measured values and target values of the intrinsic parameters.

Description

technical field [0001] The invention relates to a laser processing system and method, in particular to a laser net shaping processing system and a method for laser net shaping processing. Background technique [0002] Laser net shaping is a laser additive technique in which a high-energy laser beam is used to deposit material on the surface of an object. By repeating this method, desired parts can be processed. Laser net shaping differs from traditional machining techniques in which the desired part is formed by removing material from an object. In this way, laser net shaping has become a very promising manufacturing technology because it can significantly reduce the time required from the formation of the initial concept to the final product. [0003] During the laser net shaping process, usually the laser is first focused on the tool path (Toolpath) of the machined surface to form a molten pool on the plane. Then, the melt pool moves along the tool path with the laser a...
