Abstract Scope |
Surface finishing of Additively Manufactured (AM) parts is important to mitigate detrimental roughness textures and induce compressive residual stress. Such finishing processes often rely on surface deformation which is complicated due to anisotropy in components resulting from AM processes. Here, a workflow based on 3D finite element methods (FEM) is presented to study these effects. The evolution of Electron Beam Melted (EBM) Ti-6Al-4V surfaces during shot peening is characterized using white light profilometry. These surface profiles are then digitally scaled to create numerical work pieces comprising rough surfaces. By using indentation as a template of unit impacts during shot peening, strain energy absorption behavior of rough surfaces resulting from EBM are analyzed using the FEM-based workflow. These insights are then used to delineate the evolution in EBM surface roughness during shot peening. |
