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.
