| Abstract Scope |
The combined use of additive manufacturing (AM), metrology, and machining in integrated workflows, or hybrid manufacturing, offers benefits not available when using individual processes, including: 1) increased part complexity coupled with dimensional accuracy and surface finish; and 2) the timely and cost-effective manufacture of components for which low volume production is needed. In this research, additive friction stir deposition (AFSD) is selected as the AM process. A process sequence is described that includes AFSD, structured light scanning, and computer numerical control (CNC) machining. Results are presented for AFSD tool path generation using an open-source slicing software; tool path coordinate modification and machine code production for AFSD with non-uniform geometries; in-process temperatures to visualize the thermal history; preform measurement using structured light scanning; the use of the scanned model for machining path planning; and machining considerations. |
