摘要
论述了航空液压壳体数控编程的特点及存在的问题,针对孔及孔系特征采用目前基于CAT-IA软件的人机交互编程方法带来的编程周期长、重复工作量大、知识重用率低等难题,提出通过引入基于特征的快速编程技术加以解决.重点介绍了典型加工特征分类、工艺知识库建立、工艺决策规则定义、基于特征的快速编程系统构建等应用实践,并通过实例进行了验证.结果表明,基于特征的快速编程技术能够大幅缩短编程周期,降低重复工作量,提高编程规范性和质量一致性,促进知识积累.最后,给出了基于特征的快速编程技术的应用建议,以期为在其他类型零件或特征上的应用提供借鉴和参考.
Abstract
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.
