批量复杂结构毛坯的快速逆向建模技术研究
Rapid Reverse Modeling of Batched Complex Blanks
摘要
Abstract
The batched complex blanks with same structure and certain deviations in geometry often needed to be reconstructed .The repeated process wasted a lot of labors and extended the produc-tion cycle .An efficient reconstruction method was proposed based on the structural template and the reverse design table .Firstly ,the feature of the blank's structure was analyzed .A template representing the structure features ,as well as a reverse design table based on open knowledge representation ,was established .Secondly ,the elements in the template and the steps in the design table were utilized to segment the cloud points automatically .Thirdly ,different types of surface were reversely reconstruc-ted and post processed orderly .The experimental results validate the method’s high efficiency .关键词
