新型NC图形验证系统的方案设计

A new framework of NC graphic verification system

根据虚拟制造环境中NC图形验证的设计原则和功能分析,提出了新型复杂曲面NC验证系统的体系结构,并以分层数据流图的形式较为详尽地描述了系统内部数据的传递。该体系结构将几何验证与切削过程物理验证相结合,能够保证在此基础上构建的NC图形验证系统更加真实地反映复杂曲面数控铣削加工的实际情况,为工程技术人员提供更为准确的验证结果。

A new framework of NC verification system for complex surface was proposed according to the design principles and functional analysis of NC verification in the virtual manufacturing environment. The new structure combined geometrical verification with physical verification into one system and the transformation of system data was described by layer DFD （data flow diagram）, which make sure that the NC verification system could more accurately reflect the actual milling situation of the complex surface and provide more accurate verification results for the engineers.
