In machining, tool/workpiece interface parameters are complicated to estimate by experimental means alone. Numerical methods can then give critical solutions to predict and analyze the parameters influencing the machining. The friction between the tool and the cutter has a direct influence on the milling parameters. Therefore, it is necessary to understand the friction mechanism between the tool and the workpiece to estimate the milling parameters of Nomex honeycomb structures correctly. This work aims to present a 3D Finite Element numerical model allowing the prediction of the cutting forces correctly, the morphology of the chips, and the surface quality generated during the milling of this type of structure. These studies were obtained using the commercial software ABAQUS/Explicit. It has been demonstrated that the coupling between the isotropic elastoplastic approach and the Coulomb friction law can easily simulate the milling of Nomex honeycomb structures and gives excellent results in comparison with those obtained experimentally.

在机械加工中，工具/工件界面参数很难单独通过实验手段进行估计。然后，数值方法可以提供关键的解决方案来预测和分析影响加工的参数。刀具和刀具之间的摩擦对铣削参数有直接影响。因此，有必要了解刀具与工件之间的摩擦机理，才能正确估算出Nomex蜂窝结构的铣削参数。这项工作旨在提出一个 3D 有限元数值模型，该模型可以正确预测切削力、切屑的形态以及在铣削此类结构期间产生的表面质量。这些研究是使用商业软件 ABAQUS/Explicit 获得的。
