摘　　要：采用肯纳KYHS10陶瓷刀具对高温合金GH4169进行高速铣削正交试验,通过极差分析法研究铣削速度ν、铣削深度ap、每齿进给量fz对加工材料表面粗糙度的影响程度,分析了各加工参数对加工表面粗糙度的影响规律,并建立了表面粗糙度的预测模型,验证了预测模型的可靠性。结果表明:影响表面粗糙度的主次因素依次为铣削深度、每齿进给量、铣削速度;随着铣削速度的增加,加工表面粗糙度逐渐减小,而随着铣削深度和每齿进给量的增加,加工表面粗糙度逐渐变大。The orthogonal experiment was carried out of high speed milling of superalloy GH4169 with KYHS10 ceramic tool. The effects were studied by range analysis of milling speed,milling depth,and feed per tooth on the surface roughness of the machined materials. The influencing law was analyzed of each machining parameter on surface roughness. Aprediction model of surface roughness was established,and its reliability was verified. The results show that the primary and secondary influence factors on the surface roughness are milling depth, feed per tooth and milling speed. The surface roughness gradually decreases with the increase of the milling speed, but increases with the increase of the milling depth and feed per tooth.
