模糊理论在零件加工误差源诊断中的应用

Application of Fuzzy Theory in Error Sources Diagnosis

将模糊理论应用到零件加工质量误差源诊断中，运用模糊语言来描述零件加工中出现的现象，建立了模糊语言的数值表达式，以及误差源和其表现形式的关系表、关系矩阵，并给出了模糊贴近度的计算方法，依据最大隶属度原则诊断出产生加工误差的原因。

ln this paper, fuzzy analysis method is applied in error sources diagnosis. ln the system. the phenomina in maching are described in fuzzy language and the indeterminacy rela- tion between error sources and their phenomina are determined with weights. The table and martrix between error sources and their phenomina are established, and the computing method of fuzzy approximation degree and the formulation to translate fuzzy language is given.
