Finite Element Analysis and Fuzzy Comprehensive Evaluation of Mechanical-thermal Coupling Physical Field for Milling Insert

为获得切削性能更优良的可转位铣刀片槽型,从而改善铣刀片的力-热耦合综合物理场,进行了铣削温度试验和铣削力试验,以铣削时刀片的装夹状况和试验所获得的数据为边界条件,对带有三维槽型的波形刃铣刀片和平刀片分别进行了力-热耦合物理场有限元分析。基于模糊数学理论,建立了铣刀片耦合场的模糊综合评判模型,对两种铣刀片的力-热耦合物理场进行了模糊综合评判。结果表明,优化铣刀片前刀面的槽型可明显改善切削性能。

The milling temperature test. milling force test and finite element analysis of the mechanical -thermal coupling physical field of the wave - edge milling insert with the three - dimension groove and the flat rake plane milling insert have been carfled out to obtain the groove of indexable milling insert with better cutting performance so as to improve the mechanical - thermal cou- pling physical field. The fuzzy comprehensive evaluation of the milling insert has been built on the basis of the theory of fuzzy mathematics and the fuzzy comprehensive evaluation of the milling insert processed. The result has illustrated that the optimized milling insert groove can improve the cutting performance.
