Abstract: To meet the rapid NC programming system for quality requirements of 3D aircraft-structure model,and to quickly identify the model defects which influenced NC programming,a novel automatic method for detecting 3D aircraft-structure model based on rule-matching was proposed.According to the structural characteristics of aircraft-structure model defects,the corresponding matching rules were concluded.By using the color-coded method,the fillet surface parameters were extracted,and a set of defects detection algorithm was proposed.An aircraft-structural model was taken as an example to verify the effectiveness of proposed method.

Key words: rapid numerical control programming system, aircraft structure parts, model defects, rule-matching, decision rules, color-coded
