Application Practice and Suggestions of Rapid Programming of Aviation Hydraulic Shells based on Feature
It was discussed that the characteristics and existing problems of NC programming of aviation hydraulic shell.In response to the problems of long programming cycle,large repetitive workload and low knowledge reuse caused by the current human-machine interaction programming method based on CATIA software for holes and hole system characteris-tics,we proposed the method for solving the problems by introducing feature-based rapid programming technology.It was introduced that the typical machining feature classification,process knowledge base establishment,process decision rule def-inition,feature-based rapid programming system construction and other application practices,and it was verified by exam-ples.The results indicated that feature-based rapid programming technology could significantly shorten programming cy-cles,reduce repetitive workload,improve programming standardization and quality consistency,and promote knowledge ac-cumulation.Finally,suggestions for the application of feature-based rapid programming technology were given,which pro-vided reference and inspiration for its application in other types of parts or features.
