Abstract

Aluminum honeycomb has been widely used in various industrial sectors due to its exceptional physical properties. Ultrasonic vibration machining shows significant potential in reducing machining defects. Therefore, this study employs ultrasonic vibration assisted cutting (UVC) to process aluminum honeycomb core and compares cutting force, surface morphology, and cutting defects with the conventional cutting (CC). This investigation assesses the impact of processing parameters such as feed rate and cutting depth on both UVC and CC. The results indicate that, in comparison to CC, UVC can notably reduce cutting force, minimize tearing burrs and cell deformation defects, and achieve superior surface morphology. Furthermore, the study reveals that cutting force increases with higher tool feed rates and cutting depths. Cell deformation also escalates with increased tool feed rates and cutting depths, and tearing burrs become more pronounced with deeper cuts. Excessively shallow cutting depths can lead to a sudden increase in node defects. Simultaneously, tearing burrs and cell deformation exhibit different characteristics under CC and UVC.

纵向扭转复合超声波振动辅助切割铝蜂窝芯加工特性研究

铝蜂窝因其优异的物理特性而被广泛应用于各个工业领域。超声波振动加工在减少加工缺陷方面显示出巨大潜力。因此，本研究采用超声波振动辅助切削（UVC）加工铝蜂窝芯，并将切削力、表面形态和切削缺陷与传统切削（CC）进行比较。这项研究评估了进给速度和切削深度等加工参数对 UVC 和 CC 的影响。结果表明，与 CC 相比，UVC 能显著降低切削力，最大限度地减少撕裂毛刺和细胞变形缺陷，并获得优异的表面形态。此外，研究还发现，切削力会随着刀具进给率和切削深度的增加而增加。细胞变形也会随着刀具进给率和切削深度的增加而加剧，而且切削深度越深，撕裂毛刺越明显。过浅的切削深度会导致节点缺陷突然增加。同时，撕裂毛刺和晶胞变形在 CC 和 UVC 下表现出不同的特征。
