在切削速度范围157～1000 m/min内，综合应用析因试验与速度单因素试验，对航空用难加工材料2Cr13马氏体不锈钢进行了高速干式铣削试验。在分析其切削力显著性影响因素的基础上，对切削力随机信号进行了现代谱分析与小波分析。研究结果表明，高速切削马氏体不锈钢材料时，切削速度和每齿进给量之间的交互作用对切削力有显著影响；铣削深度和每齿进给量之间的交互作用在切削力响应信号中表现为低频周期信号；低频周期信号与高频信号叠加后，其波形的振幅将会增大。

Factorials experiment and velocity single-factor experiment are applied in the dry high-speed milling experiments of Martensitic stainless steel 2Crl3, which is used in aerospace industry. Based on the analysis of cutting regimes, influences on milling force, the spectrum analysis and wavelet analysis are applied on the random cutting force signals. This study shows that in high speed milling of Martensitic stainless process, the interaction of depth of cut and feed per tooth has significant effect on the cutting force; the interaction of feed per tooth and depth of cut introduces a lower frequency periodic signal; this low frequency signal coupled with high frequency signal could remarkably increase the amplitude of cutting force signals.
