摘要：

基于知识的工程(Knowledge Based Engineering,KBE)技术为楔横轧模具设计知识的整理、收集与重用提供了手段。本文将楔横轧轧件作为对象,采用特征表达的方法来描述轧件。建立了轧件特征的提取原则,通过对轧件的材料特征、坯料特征、主形特征3个特征类的分析,得出了楔横轧轧件特征的描述方法。重点分析了对楔横轧工艺影响较大的特征属性。采用特征表达法简单、完整的描述了轧件,简化了楔横轧知识运用的步骤以及内容,为基于KBE的楔横轧模具设计提供了知识基础。

KBE(Knowledge Based Engineering) technology provides a method to organize,collect and reuse the knowledge of CWR(Cross Wedge Rolling) mold design.CWR part was taken as an object,which was researched and described by characteristics expression method.Based on the characteristic extracting principle,the way of CWR part's characteristics expression was obtained by analyzing three characteristic classes,which were material characteristic,roughcast characteristic and part's main shape characteristic.Characteristics which had greater influence on CWR technology were introduced emphatically.The steps and content of knowledge using were simplified by simple and complete part describing based on characteristic expression,which provided knowledge foundation for CWR mold design based on KBE.
