Prediction of Residual Stress in Hard Turning of AISI 52100 Using 2D FEM

摘要

Residual stress on the machined surface and the subsurface is one of the most important factors that can influence the service quality of a component, such as fatigue life, tribological properties, and distortion. In this work, a 2D FEM model of AISI 52100 hard turning processes is setup. The material properties are widely selected to describe the material property more precisely. By using user subroutine named Konti-Cut, the steady state of cutting process is simulated and the cutting forces and residual stresses in this time are investigated. By comparing the cutting forces, the FEM model can gives quite good appliance with experimental data. And the basic relations between residual stresses and cutting parameter, tool geometry are drawn.
