Abstract

In order to address the existing challenges in the filling clamping methods of metal honeycomb core, such as slow efficiency, difficult post-processing, easy damage to the honeycomb wall, and lack of environmental friendliness, a new method called integral immersion ice fixation clamping for metal honeycomb core was proposed. This study conducted analytical calculations and test analysis on the mechanical properties of superalloy honeycomb core and artificial ice. It elucidated the mechanism of the metal honeycomb core with ice fixation constraint action and verified the effectiveness of ice fixation clamping through cutting tests and finite element simulation methods. The results indicate that introducing the ice fixation clamping method in metal honeycomb core machining provides sufficient support and adhesive strength for the honeycomb wall, reducing the maximum vibration amplitude by approximately 32.77 to 50.57%. When the height of the machined honeycomb core specimen is h ≥ 3 mm, it can prevent axial displacement of the honeycomb wall under the action of cutting force. The ice fixation clamping method improves the ability of the honeycomb core side wall to resist radial deformation and machining stability, and enables the machining quality of the honeycomb core with low damage, and low roughness. This research provides a new method and basic guidance for the reliable clamping of thin-walled porous metal components.

铣削 GH4099 超合金蜂窝芯时冰固定夹具的原理和效果
针对目前金属蜂窝芯填充夹持方法存在的效率慢、后处理困难、蜂窝壁易损坏、不环保等难题,提出了一种新的金属蜂窝芯整体浸冰固定夹持方法。该研究对超合金蜂窝芯和人工冰的力学性能进行了分析计算和试验分析。它阐明了金属蜂窝芯在冰固定约束作用下的机理,并通过切削试验和有限元模拟方法验证了冰固定夹持的有效性。结果表明,在金属蜂窝芯加工中引入冰固定夹持方法可为蜂窝壁提供足够的支撑和粘附强度,使最大振幅降低约 32.77% 至 50.57%。当加工的蜂窝芯试样高度 h≥ 3 mm 时,可防止蜂窝壁在切削力作用下发生轴向位移。冰固定夹持法提高了蜂窝芯侧壁抗径向变形能力和加工稳定性,使蜂窝芯的加工质量损伤小、粗糙度低。这项研究为薄壁多孔金属部件的可靠装夹提供了一种新方法和基本指导。

期刊介绍: The International Journal of Advanced Manufacturing Technology bridges the gap between pure research journals and the more practical publications on advanced manufacturing and systems. It therefore provides an outstanding forum for papers covering applications-based research topics relevant to manufacturing processes, machines and process integration.
