基于NX二次开发的自动提取基准信息研究

Research on Automatic Extraction of Benchmark Information Based on NX Secondary Development

近年来,随着科学技术的不断发展,数字化设计成为机械设计与制造领域中不可缺少的环节,对整个机械制造行业发展有着重大的意义。现代航空航天汽车等机械制造行业逐渐引进了MBD(Model Based Definition)数字化技术。为了解决MBD模型信息的基准信息提取等问题,本文通过NX二次开发,并以NX的开发界面为支撑,开发了程序实现了自动导入零件,使MBD模型中基准信息可导出外部excel表中。避免手动输入造成的繁琐,缩短产品研发周期,降低生产成本,提高产品质量。

In recent years,with the development of science and technology,digital design has become an indispensable link in the field of mechanical design and manufacturing,which is of great significance to the development of the whole machinery manufacturing industry. MBD( Model Based Definition) digital technology has been gradually introduced into modern aerospace and other mechanical manufacturing industries. In order to solve the problem of extracting the reference information of MBD model,this paper develops a program based on the second development of NX and based on the development interface of NX,the program realizes the automatic import of parts,so that the reference information in the MBD model can be exported to the external excel table. Avoid red tape caused by manual input,shorten R & D cycle,reduce production cost and improve product quality.
