摘要: 利用单频率法建立薄壁构件铣削稳定性及表面位置误差模型,采用Kriging方法对薄壁构件铣削稳定性及表面位置误差进行了可靠性灵敏度分析,评价铣削参数对薄壁构件铣削稳定性及表面位置误差的影响程度.研究结果表明:随薄壁构件铣削系统的阻尼比及y向刚度的增加,系统的可靠度增加;随切向力系数、固有频率、径向侵入比及轴向切深的增加,系统可靠度降低;径向力系数和每齿进给量对系统的影响较小.研究结果能为薄壁构件高速铣削加工提供合理的理论依据.

Abstract: A stability and surface position error model for the thin-walled components milling was established by using a single frequency method. The Kriging method was used to analyze the reliability sensitivity of the stability and surface position error of thin-walled components milling, and to evaluate the influence of milling parameters on the stability and surface position error of thin-walled components milling. The results show that the system reliability increases with the increase of damping ratio and y direction stiffness of the thin-walled components milling system. The system reliability decreases with the increase of tangential force coefficient, natural frequency, radial invasion ratio and axial cutting depth. The radial force factor and feed per tooth have less impact on the system. The research results may provide reasonable theoretical basis for high speed milling of thin-walled components.

Key words: thin-walled components, Kriging, milling stability, surface position error, reliability sensitivity
