文中针对哈尔滨理工大学开发的波形刃（前刀面为波形曲面）铣刀片，进行三维复杂槽型铣刀片受力密度函数分布规律的研究。在已建立的铣削力数学模型的基础上，通过铣削力试验以及刀一屑接触面积的试验，建立三维复杂槽型铣刀片前刀面的受力密度函数；对表面受力密度函数进行定量分析计算，编制计算程序对表面受力密度函数分布模型进行三维图形表示，从而分析其分布规律，为铣刀片应力场分析及槽型优选的研究打下理论基础。

英文摘要：

This paper studies on the distributing principle of force density function for complex three-dimension groove milling insert with the waved-edge milling insert （the curve rake plane） developed by Harbin University of Science and Technology. On the basis of the milling force mathematical model, the force density function of the curve rake plane is built by the milling force and chip-tool contact experiments. Having quantitative calculation on the force density function and programming, the distributing model of force density function is shown with 3D Figure, so as to analyze its distributing principle. All these studies will provide a theoretic base for the stress field analysis and groove optimization.
