在现有轴类零件相似性检索方法的基础上,将轴类零件的信息模型划分为结构特征层和加工工艺层,并利用可拓基元方法进行形式化描述.提出从轴类零件结构和加工工艺两方面进行相似性检索的方法:首先基于结构矩阵表达方法,对轴类零件的结构特征进行相似性检索,从实例库中检索出2~5个相似实例,然后以可拓综合关联函数进行加工特征的相似度匹配,得出与新零件最相似的零件.通过实例验证,该方法具有可行性,并且可在检索过程中动态调整系数水平,具有检索适应性强的优点.
在現有軸類零件相似性檢索方法的基礎上,將軸類零件的信息模型劃分為結構特徵層和加工工藝層,併利用可拓基元方法進行形式化描述.提齣從軸類零件結構和加工工藝兩方麵進行相似性檢索的方法:首先基于結構矩陣錶達方法,對軸類零件的結構特徵進行相似性檢索,從實例庫中檢索齣2~5箇相似實例,然後以可拓綜閤關聯函數進行加工特徵的相似度匹配,得齣與新零件最相似的零件.通過實例驗證,該方法具有可行性,併且可在檢索過程中動態調整繫數水平,具有檢索適應性彊的優點.

The information model of axis class parts are di-vided into structure feature layer and machining feature layer based on the similarity retrieval method of existing axis class parts. The extensible basic elementmethod is used for the formal description. The method makes similarity retrieval from the struc-ture and machining process aspects are provided. At first, the structure features perform the similarity retrieval based on the method of structure descripted by matrix,2~5 similar cases will be searched in the instance database. Then, the best similarity part is selected by the method, which is applied in similarity match of machining feature using extension comprehensive corre-lation functions. The good feasibility of this method is verified by a simple example, and the method has an advantage that its a-daptability and derivative are strong, with the level adjustment of coefficient in retrieval process.
