Analysis of friction and cutting parameters when milling honeycomb composite structures
Abstract
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.
