摘　　要：螺纹铣削作为一种先进的螺纹加工方法,研究其加工过程中切削力和切削温度的变化规律对提高刀具使用寿命及被加工表面质量具有重要的现实意义。以某可转位螺纹铣刀铣削加工45#钢为研究对象,在三维设计软件Pro/e中建立刀具三维实体模型,并导入金属切削工艺有限元软件AdvantEdge中进行铣削加工模拟仿真,得到加工过程中切削力和温度随时间的变化关系,对比分析了不同进给量的选择对切削力和切削温度的影响,分析结果为实际螺纹铣削加工及其进给量的选择提供参考。Thread milling is an advanced thread machining method,it has important practical significance for improving the tool life and the quality of machined surface to study the change rule of cutting force and cutting temperature in the machining process.Firstly,the 3D solid model of an indexable thread milling cutter is established in 3D design software Pro /e,the cutter is used to mill 45# steel.Secondly,the AdvantEdge which is a metal cutting process finite element software is used to simulate the thread milling process,and the relationships of cutting force and cutting temperature changing with time are obtained.Then,the effect of different feed rate on cutting force and cutting temperature is comparatively analyzed.The analysis results provide a reference for the actual thread milling and the selection of feed rate.
