The Integrated Digital Manufacture of Airplane Duct Based on through Process and Three Dimensional Modeling

Abstract

This study introduces the current states and progress of the overseas digitization manufacture technology of airplane ducts, and analyzes the problems about manufacture technology of bent tubes in airplane production in China. Thus, instead of the full pattern, the three-dimensional models are proposed to conduct the NC(Numerical Controling) bending and examine the bending quality, and the integrated digitization manufacture technology of airplane ducts is developed. The key problems are solved including standardization modeling of ducts, 3D data transfering, virtual processing analysis, digital modular fixture design/manufacturing, and NC bending/manufacturing/inspection of ducts. The technology has been successfully applied into the digital forming manufacturing of airplan ducts.
