Abstract

The invention provides a process monitoring system and method for laser additive remanufacturing equipment. The process monitoring system comprises a processing bin, a laser device assembly, a base plate, a scraper assembly, a material cylinder, a powder overflowing opening, a scraper limiting switch, a camera shooting assembly, a controller and an image processor. The processing state in the processing bin is monitored and recognized in real time through the camera shooting assembly and the image processor, recognition is conducted based on the gray difference of the image area, the position of a sudden change point is found around a mass point in the image area, and if the sudden change point reaches a preset value, the sudden change point is detected. And if the problems of buckling deformation, uneven powder laying and the like occur in workpiece processing, an alarm is triggered, so that the processing state of the workpiece in the processing bin can be conveniently, quickly and automatically detected, workers can timely process, the quality problem of the produced workpiece is effectively ensured, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of laser additive manufacturing, in particular to a process monitoring system and method for laser additive remanufacturing equipment. Background technique [0002] Laser 3D printer is a machine of rapid prototyping technology, which integrates mechanical engineering, material engineering, numerical control technology, laser technology and other technologies. It is a digital model file based on the use of powdered metal or plastic and other adhesive materials , The technology of constructing objects by layer-by-layer printing is a cumulative manufacturing technology. Three-dimensional objects are produced by printing layers of adhesive materials. The basic principle is that by putting data and raw materials into the 3D printer, The machine will build the product layer by layer according to the program, and the printed product can be used immediately. [0003] The more mainstream methods include stereolithog...
