Numerical Modeling the Effect of Tool-Chip Friction in Orthogonal Cutting AISI4340

Abstract:

A thermo-elastic-plastic model using explicit finite element code ABAQUS 6.8 was developed to investigate the effect of tool-chip friction in orthogonal cutting AISI4340. A.L.E finite element model was presented and the Johnson-Cook plastic model was used to model the workpiece material which is suitable for modeling cases with high strain, strain rate, strain hardening, and non-linear properties. In this paper, three different friction coefficient values of 0.2, 0.3, 0.4 were considered to study the effect on Cutting temperature, cutting forces and cutting stress. The results told a clear understanding of the effect of friction coefficient in orthogonal metal cutting, and larger friction coefficient induced higher cutting temperature, bigger cutting forces and larger cutting stress.
