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,进行三维复杂槽型铣刀片物理场分析。在已建立的铣削力数学模型的基础上,建立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;在铣削温度数学模型基础上,建立波形刃铣刀片表面受热密度函数;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,探讨耦合情况下等效应力的分布规律和受力变形状况。Taking the waved-edge milling insert （the curve rake plane） developed by the Harbin University of Science and Technology as an example, this paper has the analysis on the physics fields for the complex three-dimension groove milling inserts. On the basis of the milling force mathematical model, 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 mathematical model, we build the heat density function for the waved-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.
