Abstract:Aiming at the machining problems of metal honeycomb core, such as thin-walled porosity, anisotropy, weak in-plane rigidity and low radial strength, a ice fixation and low damage machining method of superalloy honeycomb core was proposed. The principles of metal honeycomb core ice fixation clamping were analyzed, the adaptability and reliability of the machining systems were verified. A single factor test of honeycomb core ice fixation cryogenic cooling machining was carried out, the forming rule of honeycomb core machining defects was expounded. The results show that the clamping and machining methods of ice fixation cryogenic cooling are introduced in the machining of metal honeycomb cores, the cutting heat is reduced and the fixation constraint retention achieves during machining, which may improve the ability of the honeycomb wall to resist deformation . Among the cutting parameters, the feed rate has the greatest influence on the machining quality, and the tearing burr accounts for the highest proportion of the machining defects. The optimal cutting parameters may ensure good machining quality with low damage, low roughness and no deformation, and may achieve high quality and high efficiency machining of difficult-to-machine metal honeycomb cores.
Keywords:honeycomb core  ice fixation  cryogenic cooling  superalloy  artificial ice
