Numerical investigations on residual stresses in orthogonal cutting of Ti-6A1-4V

Zhuang, Kejia ; Huang, Yujian ; Weng, Jian ; Zhang, Delai and Zhou, Jinming LU (2022) 6th CIRP Conference on Surface Integrity, CSI 2022 In Procedia CIRP 108. p.199-204
Abstract

Titanium is widely employed in aerospace space, where the surface integrity plays an important role in part quality. This paper presents the numerical and experimental results of residual stress when machining Titanium based on a CEL (Coupled Eulerian-Lagrangian) method. The performance of proposed model is compared with LAG (Lagrangian) and ALE (Arbitrary Lagrangian-Eulerian) methods regarding segment chip formation and residual stress. The correctness of simulation results is validated by orthogonal cutting experiments of Ti-6Al-4V as well as the experimental data given in recent published literature. The effects of uncut chip thickness, cutting velocity and edge radius on residual stress are discussed through simulation results.
