摘要
采用正交试验方法,使用PCBN涂层硬质合金球头铣刀,对不同铣削参数下的52HRC淬硬钢Cr12MoV倾斜表面进行了铣削试验。研究了各工艺参数对切削力的影响规律。试验结果表明:三向力中,Fz远大于Fx和Fy的切削分力,Fz为主铣削力;切削深度对主铣削力的影响大于进给速度、工件倾角和主轴转速对其的影响;工件倾角16.7°,主轴转速6000r/min,进给速度800mm/min,切削深度0.1mm为优选工艺条件。同时,对比试验表明,采用顺铣方式能有效减小切削力,改善铣削稳定性。本文研究结果对淬硬钢Cr12MoV铣削工艺参数的优化具有一定的参考价值。
Orthogonal experiment method was applied to milling experiment on hardened steel inclined surface CrI2MoV （52HRC） under different milling parameters, with cemented carbide ball end milling of PCBN coating. The effect of different milling parameters on cutting force was studied. The experiment results show that, for three - axis cutting force, the cutting force Fz is much larger than the force components of Fx and F, named the main milling force. The influ- ence of cutting depth for the cutting force is greater than the feeding speed, work - piece inclination and spindling speed. The work -piece inclination 16.7, spindling speed 6000r/min, feeding speed 800mrrr/min and cutting depth 0.1 mm are optimum process conditions. Meanwhile, contrast test shows that climb milling is applied to reduce cutting force and improve milling stability. The analysis result can provide reference value for the optimization of milling process on hardened steel Cr12MoV.
