Whirling has been adopted for the cost-effective machining of blade-shape components in addition to traditional end milling and flank milling processes. To satisfy the requirements of rotary forming in the blade whirling process, the workpiece must be clamped at both ends in suspension and rotated slowly during machining, which complicates the dynamics. This study aims to identify the dynamic characteristics within the blade whirling operation and present strategies for stability prediction. In this study, the dynamic characteristics of a whirling system are modeled by assuming symmetric and asymmetric parameters. Theoretical prediction frequency response function (FRF) results are compared with experimental results. Moreover, semi-discretization stability lobe diagrams (SLDs) obtained using the dynamic parameters of these models are investigated experimentally. The results show that the asymmetric model is more suitable for describing the whirling system, whereas the symmetric model presents limitations associated with the frequency range and location of measuring points. Finally, a set of airfoil propeller blade whirling operations is conducted to verify the prediction accuracy.

除传统的立铣刀和侧面铣削工艺外，旋风磨削还被用于经济高效地加工叶片形零件。为了满足叶片回旋过程中旋转成型的要求，必须将工件的两个端部悬吊并在加工过程中缓慢旋转，这使动力学变得复杂。这项研究旨在确定叶片旋转运动中的动态特性，并提出稳定性预测策略。在这项研究中，通过假设对称和不对称参数对回旋系统的动态特性进行建模。将理论预测频率响应函数（FRF）的结果与实验结果进行比较。此外，实验研究了使用这些模型的动态参数获得的半离散稳定性波瓣图（SLD）。结果表明，非对称模型更适合描述回旋系统，而对称模型则存在与频率范围和测量点位置相关的局限性。最后，进行了一组翼型螺旋桨叶片旋转操作，以验证预测精度。
