AbstractResidual stress is of great importance on the fatigue life of components; nevertheless, most of the simulations of turning operation focus on the first cut and ignore the evolution of residual stress in sequential cutting. The present study aims to explore the surface residual stress profile along the feed direction during longitudinal turning, to understand the impact of sequential cuts on turning-induced residual stress.
