Additive Manufacturing offers a unique method to manufacture superalloys with complex geometry. However, metal AM products suffer from poor surface finish and limited accuracy. Hence, there is a growing need for integrated metal hybrid manufacturing. AM parts are inherently different from traditionally manufactured parts in anisotropy. A critical gap revealed the need to correlate as-built material properties and microstructure on resulting machining behavior. This presentation reports the influence of AM processes, build orientation, and heat treatment on Ti6Al4V AM parts microstructure with correlated machining behavior. We found the EBM, LPBF, and DED processed Ti-6Al-4V parts show significantly different responses to specific cutting energy. Also, build orientations and heat treatment conditions significantly affect the parts machining behavior. Finding from this study can be used to predict machining behavior based on material characterization. Future research will create models to correlate parts characterization data with machining energy, surface finish, tool wear. |
