Abstract

Improper tool trajectory selection during CFRP curved component milling can lead to sudden changes in instantaneous cutting parameters, such as fiber cutting angle, resulting in significant machining damage and profile deviation. In this paper, a novel tool trajectory planning method for CFRP curved component milling is proposed. The key innovation of this method lies in considering the effect of tool variable inclination on fiber removal behavior. Employing the developed method, the influence of trajectories under different tool inclination angles on the milling quality of CFRP surfaces is thoroughly investigated. The results indicate that, to minimize machining damage, an inclination angle within 10° is recommended when the fiber cutting direction is in the range of 0°-60° and 150°-180°. For fiber cutting directions falling within 60°-150°, it is recommended to select an inclination angle above 25°. Additionally, the novel tool trajectory planning method decreases CFRP surface profile errors by over 20 %.

用于 CFRP 曲面部件铣削的刀具轨迹规划方法：考虑可变倾角以适应纤维层的不同方向

在 CFRP 曲线部件铣削过程中，刀具轨迹选择不当会导致纤维切削角等瞬时切削参数发生突变，从而造成严重的加工损伤和轮廓偏差。本文提出了一种新型的 CFRP 曲面部件铣削刀具轨迹规划方法。该方法的关键创新点在于考虑了刀具可变倾角对纤维去除行为的影响。利用所开发的方法，深入研究了不同刀具倾角下的轨迹对 CFRP 表面铣削质量的影响。结果表明，当纤维切削方向在 0°-60° 和 150°-180° 范围内时，为最大限度地减少加工损伤，建议采用 10° 以内的倾角。纤维切割方向在 60°-150° 范围内时，建议选择 25° 以上的倾斜角。此外，新型刀具轨迹规划方法可将 CFRP 表面轮廓误差降低 20% 以上。
