The effect of the failure criterion in the numerical modeling of orthogonal metal cutting

OSTI ID:6320188
Numerical modeling of metal cutting using the finite element method has been successfully used to show that assumed material properties have a large effect on such machining process parameters as the required tool forces, chip morphology, and residual stresses in the finished surface. Finite element results show that workpiece material properties such as assumed isotropic or kinematic hardening, the work hardening and work softening stress-strain behavior, the friction factor between the tool and the workpiece materials, and the failure criterion for the workpiece material all have a significant effect on the predicted cutting forces, chip shape, and workpiece residual stresses. The failure criterion for the workpiece material in the numerical modeling is used to describe the separation of the chip from the workpiece at the tool tip.
