Abstract

The invention relates to a system for obtaining a defect part model of a damaged part. The system comprises a computer and a scanner electrically connected with the computer. A modeling method comprises the following steps of (1) performing pre-scanning preparation on a to-be-scanned damaged part; (2) calibrating the scanner; (3) performing parameter configuration by the system; (4) performing scanning through the scanner to obtain initial model data; (5) processing the initial model data to obtain point cloud model data; (6) processing the point cloud model data through a mesh reconstruction algorithm to obtain a curved surface reconstruction model; (7) performing registration alignment on the curved surface reconstruction model and a standard part model; and (8) obtaining the defect part model of the to-be-scanned damaged part: after the registration alignment of the models, performing subtraction Boolean operation on the curved surface reconstruction model and the standard part model to obtain the digital model of the defect part of the to-be-scanned damaged part. The modeling method is high in modeling efficiency and high in precision.

Description

technical field [0001] The invention relates to the technical field of additive remanufacturing, in particular to a system for obtaining a model of a damaged part's defect. Background technique [0002] Additive remanufacturing technology is an advanced forming repair technology that has been rapidly developed in recent years to restore the defect size and service performance of damaged parts (components). This technology is based on the "value" cycle theory of the whole life of zero (component) parts, with damaged zero (component) parts as the object, with high quality, high efficiency, energy saving, material saving and environmental protection as the criteria, and characterized by multidisciplinary integration It is a general term for a variety of advanced technologies to maximize the use of the "residual value" of damaged zero (component) parts, while restoring their original geometric dimensions, and to restore or even improve their service performance. Its outstanding...
