Abstract: The paper presents a Finite Element Modelling (FEM) of the turning process on the Nickel superalloy IN718 produced by the Direct Energy Deposition (DED) to predict the residual stress. The material behaviour was implemented by a customized user-routine to take into account the anisotropy of the material due to the DED process. The residual stresses were experimentally measured on the surface and beneath the machined surface and the data collected were used to validate the FEM model.
