| Abstract Scope |
It is widely known that additively manufactured (AM) metal parts require post-processing to achieve dimensional tolerances comparable to those of cast or wrought metals. One common post-processing technique is machining, but AM alloys can respond differently to machining due to their unique microstructures formed in the thermal cycle. This research attempts to characterize the machinability of two alloys in turning, Ti64 and A205 aluminum, using conventionally made rods as a baseline to compare to AM equivalents. The main variables are feed and speed. In each cutting test, vibrational response, specific cutting energy, surface roughness, and images of the chips and cut surface are recorded to assess the machinability. The results show noticeable differences between AM and baseline parts in vibration and surface finish. These differences are correlated to and can be explained by the differences in their microstructures. Machining recommendations are provided at the end of this study. |
