基于密度函数的三维复杂槽型铣刀片物理场分析

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,在铣削力数学模型基础上,通过铣削力试验以及切屑与前刀面接触面积试验,建立了三维复杂槽型铣刀片前刀面的受力密度函数;基于该函数,对波形刃铣刀片进行了应力场分析。在铣削温度数学模型基础上,运用传热学理论,建立了波形刃铣刀片表面受热密度函数;基于该函数,对波形刃铣刀片进行了温度场分析。这些研究结果可为槽型优选技术的研究打下理论基础。

Physics Fields Analysis of Milling Insert with 3D Complex Groove Based on Density Functions

Taking the waved-edge milling insert (the curved rake plane) developed by the Harbin University of Science and Technology as an example, based on the milling force mathematical model, the force density function of curved rake plane was established through the milling force and chip-tool contact experiments, and the stress field analysis was carried out based on this function. Based on the milling temperature mathematical model, the heat density function of waved-edge milling insert was built up by using the heat exchange theory, and the temperature field analysis was carried out based on this function. All these studies have laid down a theoretic base for the groove optimization technology.
