Analysis of friction and cutting parameters when milling honeycomb composite structures

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