材料切削加工性的多算子二阶综合评判模型

A Model of Multi-operator,Two-level Machinability Multi-factorial Evaluation

以 Fuzzy 数学为工具按照汪培庄等提出的综合评判原理.对文献[3],[4]所给的模型进行了补充和完善,提出了材料切削加工性的多算子、二阶综合评判的数学模型.在单因素评判中,引入了相应的隶属函数:在多因素评判中.综合考虑了四种不同 Fuzzy 算子模型的评判结果。最后.提供了此模型的应用实例.

By means of Fuzzy mathematics,based upon the multi- -factorial evaluation principle proposed by professor Wang peizhuang, the models in references(3,4)are improved and hencefore,a mathematieal model of multi-operator,two-level machinability multi-factorial evaluation is advanced in this paper.Proper subordinate functions are provided for the single-factor evaluations.Four different kinds of Fuzzy evaluation models are considered for the multi-factorial evaluation. Finally,examples applying this model are provided.
