On the machining induced residual stresses in IN718 nickel-based alloy: Experiments and predictions with finite element simulation
Process parameter effects on residual stresses on IN718 material are investigated. Simulation of chip formation process is used with a modified material model. Influence of friction and material model on stress profiles is reported. Simulation models are validated with comparison of measured and predicted stresses. Stress profiles can be better represented by using average and standard deviations.
