基于CBR的钣金工艺实例表达及实例库建立

Research on Sheet Metal Process Case Representation and Case Base Building

结合特征描述法和分类编码法,建立基于特征和编码的钣金工艺信息模型,并提出了基于XML的工艺规程表达,实现钣金工艺实例的多层次描述。同时根据R5模型的原理,对不同类的钣金零件,采用不同的相似性关系建立钣金工艺实例库。

Combining the method of character description and the method of class coding. we built the model of sheet metal process information. Based on the technology of XML, we put forward the process expression. Thereby we carried out multi-levels representation of sheet metal process cases. According to the theory of the R^5 model, we adopted different similarity methods to build case bases.
