具有复杂内腔和外形的斗齿快速逆向设计
The rapid reverse design of excavator bucket teeth with both complex inner cavity and outer shapes
摘要
Abstract
To obtain physical models and CAD drawings of the point cloud reverse modeling of a bucket tooth of a certain excavator, quickly materialized method of the bucket tooth point cloud was studied. Reverse design approach which based on the "surface reconstruction-materialized-drawings" was adopted, reverse strategy include using Imageware software to complete surface reconstruction of the cavity and pin hole area which have high precision, and using Geomagic Studio software to complete surface reconstruction of the general shape of the bucket tooth, and u-sing Pro/E software to complete the surface merger and materialization was proposed. The main processes and methods included tooth point cloud data segmentation, surface reconstruction and consolidation, as well as materialization and the access to get engineering drawing was described. The results show that: for bucket teeth with many and complicated molded surfaces, the selection of the tools of reverse the surface and the data methods to segment the point cloud determine the efficiency of reconstruction of the surface and entity and if its success or failure. It will significantly improve the efficiency of the reverse design if we select appropriate strategies and tools to reverse, simplify rational point cloud segmentation, and surface reconstruction and consolidation, and the process of building physical models.关键词
