Abstract：The current aircraft automatic drill off-line programming has the disadvantage of high degree of manual participation, low efficiency and unable to prevent quality problems. To solve this problem, an offline programming method based on database and defined label is proposed. According to the process characteristics of aircraft automatic drilling, the off-line programming process is established. According to the requirement of offline programming data, the programming database is established. Combined with the database and MBD model, the information extraction rules of fastener, lamination, thickness and process parameters are formulated. The tag based process information expression and equipment attitude control are realized in DELMIA by using the characteristics of attribute feature, direction feature and point feature of label. Finally, the transformation of label in product coordinate system and equipment coordinate system is analyzed, and the correct output of processing program coordinate value is realized.
