| Abstract Scope |
Hybrid Wire Arc-Additive Manufacturing (hWAAM) couples one or more manufacturing processes with Wire Arc-Additive Manufacturing (WAAM) to improve part quality, functionality, or efficiency. When integrated with a CNC machine, hWAAM is capable of subtractive machining operations between deposited layers. The addition of interlayer machining (ILM) introduces new variables to the deposition process, such as chip load, material removal amounts, and machining frequency, which are not well explored in relation to their effect on material properties. This study focuses on the effects of ILM on thin wall aluminum ER5556 deposited material. Mechanical properties of deposited material with varied ILM parameters will be compared through sub-scale tensile testing. Variations in microstructural features including grain size, orientation, and phase distribution will be analyzed through Scanning Electron Microscopy (SEM) and optical microscopy, and effects on porosity will be determined through X-ray Computed Tomography (XCT) scanning. |
