摘　　要：以哈尔滨理工大学开发的波形刃(前刀面为波形曲面)铣刀片为例,以最小粘结破损为目标,进行铣刀片槽型优化目标函数的研究。在已建立的三维复杂槽型铣刀片受热密度函数的基础上,进行铣刀片不同切削参数下的温度场有限元分析,应用模糊数学理论对温度场进行模糊综合评判,建立温度场模糊评判结果与粘结破损切削参数之间的目标函数关系,从而进行目标函数的槽型优化设计。上述研究成果为铣刀片的开发及解决自动化生产中刀具破损这一关键技术问题的研究打下理论基础。This article takes the waved-edge of Science and Technology as an example insert （the curve rake plane） developed by Harbin University , as the goal of minimal adhering disrepair, the optimization object function of the milling insert grooves is studied. Based on the heat density function of the 3D complex groove milling insert, we have the finite element analysis on the temperature field of different cutting parameters, and have fuzzy comprehensive judgement with fuzzy mathematic theory. We build the object function relation between the fuzzy judgement result and cutting parameters of adhering disre- pair, so to have optimization groove design. All these studies provide the theoretic basis for the groove development and the cutter disrepair which is the key problem in the automatization production and groove optimization.
