Abstract

The invention discloses an intelligent laser remanufacturing method and system. The intelligent laser remanufacturing method comprises the steps that a point cloud data model of a part to be repairedis obtained, and the point cloud data model is compared with a standard CAD model of the part to be repaired to distinguish an area to be repaired; a coating path is automatically generated through apath autonomous planning module, and initial process parameters are determined by using an intelligent algorithm based on a process parameter database; the defocusing amount is automatically adjusted,and an initial machining position is determined; and combined with a visual algorithm, the process parameters are adjusted in real time by monitoring the change of the shape and temperature of a molten pool, and the closed-loop feedback control of the laser cladding process is realized. The intelligent laser remanufacturing method and system have the characteristics of automation and intelligence, are suitable for the surface repair of medium and large structural parts, can reduce an operation threshold of a laser remanufacturing industry, and improve the machining quality of laser coating.

Description

technical field

[0001] The invention relates to the field of advanced manufacturing and automation, in particular to an intelligent laser remanufacturing method and system, and the system has the characteristics of automation and intelligence. Background technique

[0002] With the rapid development of laser applications and the continuous reduction of laser application costs, laser processing is increasingly widely used in various industries. The laser remanufacturing technology supported by laser cladding as the main technology can repair high value-added parts and prolong the service life of equipment, and has a good market application prospect. At present, laser remanufacturing equipment has the following shortcomings:

[0003] 1. Laser cladding is a complex physical process involving the interaction between laser beam, powder gas flow and molten pool. It is of great significance to determine the initial processing parameters reasonably to obtain high-quality cladding ...
