This study investigates the cutting response of AL3003H18 hexagonal honeycombs loaded with vertical array blades. Quasi-static cutting tests were performed on aluminum honeycombs of various cell sizes and the same single-walled thickness (0.04 mm) using five groups of parallel steel blades of thickness 0.24 mm. The deformation mechanism was numerically simulated in the explicit solver LS-DYNA. In addition, the cutting process was described using a theoretical model based on dimensional analysis. The cutting response of honeycombs could be divided into three stages: elastic, transitional, and stable cutting. The cutting stress was found to decrease with increasing single-walled edge (SE) length. In an empirical analysis, the cutting force equation was derived as $\mathit{F}=1.3C{N}_{\text{c}}{\sigma }_{\text{y}}{t}^{1.92}{d}^{0.30}{\mathit{l}}^{-0.22}$, where C is a constant, $N_{\text{c}}$ is the total number of cutting points, ${\sigma }_{\text{y}}$ is the yield strength of the matrix material, d is the cutting depth, and t and l are the thickness and length of an SE, respectively. In particular, the cutting force is proportional to the 0.30th power of the cutting depth and inversely proportional to the 0.22th power of the SE length.

本研究调查了装有垂直阵列刀片的AL3003H18六角形蜂窝的切削响应。使用五组厚度为0.24 mm的平行钢刀片，对各种泡孔尺寸和相同单壁厚度（0.04 mm）的铝蜂窝进行了准静态切割测试。在显式求解器LS-DYNA中对变形机制进行了数值模拟。另外，使用基于尺寸分析的理论模型描述了切割过程。蜂窝的切割响应可以分为三个阶段：弹性切割，过渡切割和稳定切割。发现切削应力随着单壁刃口（SE）长度的增加而减小。在实证分析中，切削力方程为$\mathit{F}=1.3C{ñ}_{\text{C}}{\sigma }_{\text{ÿ}}{Ť}^{1.92}{d}^{0.30}{\mathit{升}}^{-0.22}$，其中C是一个常数，${ñ}_{\text{C}}$ 是切割点的总数， ${\sigma }_{\text{ÿ}}$是基体材料的屈服强度，d是切削深度，t和l分别是SE的厚度和长度。特别地，切削力与切削深度的0.30次方成正比，与SE长度的0.22次方成反比。
