本研究提出一种多轴振动辅助板料渐进成形新方法，并借由振动式刀具路径及椭圆头刀具设计来实现。该过程已被证明，以提高测试材料的可成形性，由于低频率和高振幅的振动场的引入。为了了解MV-ISF工艺的成形特性，通过实验和有限元分析，对两种铝合金成形圆锥几何形状的几何精度、表面质量和成形性进行了研究，并与传统ISF刀轨设计成形的圆锥几何形状进行了比较。还提出了振动条件下的材料变形的分析模型，以评估MV-ISF过程的增强的成形性。新的振动刀具路径设计与椭圆头刀具的使用相结合，为提高ISF制造零件的成形精度、表面质量和可成形性提供了一种简单且潜在有效的解决方案。
In this study, a new multi-axial vibration assisted incremental sheet forming (MV-ISF) process is introduced by developing a vibrated toolpath and an ellipsoidal headed tool design. The process has been shown to improve the formability of tested materials due to the introduction of a low-frequency and high-amplitude vibration field. To understand the forming characteristics of the MV-ISF process, the geometrical accuracy, surface quality and formability in forming a conic geometry are investigated through experiments and finite element analysis using two aluminium alloys and compared with that formed using the conventional ISF tool path design. An analytical model of the material deformation under the vibration condition is also proposed to assess the enhanced formability of the MV-ISF process. The new vibrated tool path design combined with the use of the ellipsoidal headed tool provides a simple and potentially effective solution for improving the forming accuracy, surface quality and formability of ISF manufactured parts.
