Abstract
Metal-Hybrid Additive Manufacturing incorporates the precision, tolerance and surface finish of subtractive manufacturing with the complex geometries allowable by Additive Manufacturing (AM). Machining conditions such as cutting direction, feed rate, depth of cut, tool geometry, and coolant significantly impact the resulting microstructures and mechanical properties of hybrid AM part. In this study, the influence of machining conditions on Electron Beam AM fabricated Ti-6Al-4V is analyzed for: (1) Orthogonal vs. Peripheral milling, and (2) Dry Machining vs. Cryogenic Machining. Material characteristics of the machined AM part including: (1) Microstructure, (2) Microhardness, (3) Surface Roughness, and (4) Electron Backscatter Diffraction (EBSD) will be compared to known properties from traditional subtractive manufacturing methods. The results from this research will help understand the effect of post-processing on the materials properties of metal AM parts and aid in the adoption of hybrid AM manufacturing based on applications.
