Abstract

The invention relates to a metal additional material manufacturing system and an online real-time tracking monitoring system therefor, and the system comprises a laser position detection module, a laser speed detection module, a laser intensity detection module and a central controller. The laser position detection module is used for carrying out the real-time detection of the position of a laserbeam and carrying out the comparison of the position with a preset slicing track. The laser speed detection module is used for carrying out the real-time detection of the moving speed of the laser beam, and comparing the real-time speed with preset laser beam moving speed information. The laser intensity detection module is used for carrying out the real-time detection of the intensity of laser acting on powder and comparing the intensity with the preset laser processing intensity information, thereby achieving the real-time regulation and control of the process.

Description

technical field [0001] The invention relates to an online real-time tracking monitoring system for metal additive manufacturing and a metal additive manufacturing system with the online real-time tracking monitoring system. Background technique [0002] In recent years of research at home and abroad, additive manufacturing technology has made a qualitative leap, but it has not yet formed a large-scale industrial application. In the manufacturing process, the performance and manufacturing accuracy of the molded parts will be substandard to a certain extent. The current yield of SLM products is about 70%, which seriously affects the process of large-scale industrial manufacturing. The main reason is that the process repeatability and quality reliability problems in the processing process have not been solved by substantial reliability. At present, in the field of aerospace, because most of the devices are large-scale components, the general additive manufacturing process take...
