摘要

在研究利用内R 成型铣刀加工孔口圆角工艺方法的基础上，针对TB6 高强度钛合金材料，设计并开展了基于铣削参数的正交疲劳性能测试试验，分析了内R 成型铣刀的最大切削线速度vc、每齿进给量fz 和切削深度ap 对试件疲劳寿命的影响规律，得到对TB6 钛合金材料疲劳极限影响最大的铣削参数是每齿进给量，其次是切削深度和线速度。基于试件的疲劳寿命测试数据对铣削参数进行优化，得到使TB6 试件疲劳极限最高的铣削参数为vc=20m/min，fz=0.04~0.08mm/z，ap=0.1mm。

Abstract

Based on the process of orifice chamfer machining with inner R forming milling cutter

orthogonal milling experiments on TB6 were carried out to analyze the influence of maximum cutting speed vc

feed per tooth fz and cutting depth ap on the fatigue life of test specimens. The results show that the effect of feed per tooth on fatigue life is more pronounced than the effects of cutting depth and cutting speed. Meanwhile

under the milling conditions of experiments

the milling parameters are developed as vc=20m/min

fz=0.04–0.08mm/z

ap=0.1mm

which can make the fatigue life longest.
