摘　　要：对波形刃铣刀片(前刀面为波形曲面)进行了力热实验研究及物理场分析.进行铣削力实验,建立了波形刃铣刀片前刀面的受力密度函数.在受力密度函数的基础上,对波形刃铣刀片进行应力场分析;在铣削温度实验基础上,建立波形刃铣刀片表面受热密度函数;又在受热密度函数的基础上对波形刃铣刀片进行温度场分析;最后,对波形刃铣刀片的温度场和应力场进行耦合分析,探讨耦合情况下的等效应力的分布规律和受力变形状况.以上工作为槽型优选技术的研究打下理论基础.For the waved-edge milling insert（the curve rake plane） developed by the Harbin University of Science and Technology,this paper analyzes force and heat experiments and physics fields analysis.On the basis of the milling force experiments,we build the force density function for the waved-edge milling inserts.We have the stress field analysis based on the force density function.Based on the milling temperature experiments,we build the heat density function for the waved-edge milling insert.We have the temperature field analysis based on the heat density function.In order to discuss the distribution principle of equivalent stress and distortion under coupling condition,we have the coupling analysis on the stress field and temperature field.All these studies will provide a theoretic base for the groove optimization technology.
