Three-Dimensional Finite Element Analysis on Precision Cutting for Tool with Nose Radius Considering Tool Edge Radius
The finite element modeling and experimental validation of three-dimensional precision cutting of 3J33 maraging are presented. The commercial software MARC applied for the finite element modeling is studied the effect of tool nose radii considering tool edge radius on the principal cutting forces and the temperature fields. The model employs an updated Lagrangian formulation. The friction between the tool and the chip is assumed to follow a modified Coulomb friction law and the adaptive remeshing technique is using for the formation of chip. The tool edge radius significantly affects the cutting forces and the maximum temperature of the chip. The simulation results for tool with nose radius considering tool edge radius are compared with experimentally measured data and found to be in good agreement.
