摘要

针对复杂曲面薄壁叶片点铣加工刀位的特点

建立了平均铣削力预测模型

利用多因素正交试验法对铣削力系数进行了标定

并验证了该模型的正确性.在此基础上

考虑了铣削力与弹性变形之间的耦合效应

提出了复杂曲面薄壁叶片点铣加工过程中弹性变形量计算的迭代格式

并利用Matlab和Ansys集成实现了薄壁叶片在各刀触点处弹性变形量的计算.试验结果表明

弹性变形预测值与实际加工测量值之间的最大偏差为27.255μm

最小偏差为2.001μm

平均偏差为11.164μm

预测结果与实际结果十分吻合.

Abstract

According to the cutter location characteristics of complex surface thin-walled vane in ball end milling process

an empirical formula considering tool inclination angle of average cutting force is established. The undetermined coefficients are calibrated by orthogonal test

and then the validity of this empirical formula is verified with AdvantEdge software. Noting the coupling relationship between cutting force and elastic deformation

and taking cutting depth

cutting width and tool inclination angle as the feedback variables

an iteration format for calculating elastic deformation is suggested

by which the elastic deformation at each cutter contact point of a complex surface thin-walled vane is calculated combining Matalb and Ansys softwares. It is shown that the predicted and experimental results well coincide

the maximum deviation gets to 27.255 μm

the minimum to 2.001 μm and the average to 11.164 μm.
