The Industrial Ontologies Foundry (IOF) Core Ontology

September 19, 2022
Author(s)
Boonserm Kulvatunyou, Milos Drobnjakovic, Farhad Ameri, Chris Will, Barry Smith
The Industrial Ontologies Foundry (IOF) has been formed to create a suite of interoperable ontologies that would serve as a foundation for data and information interoperability in all areas of manufacturing. To ensure that the ontologies are developed in a

Data organization in laser-based powder bed fusion for metals

September 16, 2022
Author(s)
Shaw C. Feng, Albert T. Jones, Shengyen Li, Mostafa Yakout
Data analytics (DA) and artificial intelligence (AI) have been chosen as the technologies for extracting new knowledge and making better decisions in additive manufacturing (AM) processes. They have been chosen because accurate and complete physics-based

Measuring downstream supply chain losses due to power disturbances

September 16, 2022
Author(s)
Douglas Thomas, Juan Fung
Power outages in the U.S. affect many firms' economic activity and are likely to result in downstream supply chain disruptions. This paper examines the impact of power disturbances in the supply chain for four industries: manufacturing, durable goods

The Strategy for American Leadership in High-Consequence Additive Manufacturing

September 9, 2022
Author(s)
Mark Benedict, Shawn P. Moylan, Souhail Al-Abed, Cindy Ashforth, Y. Kevin Chou, Matthew Di Prima, Alaa Elwany, Michael Gorelik, Astrid Lewis, Todd Luxton, Blake Marshall, William Mullins, Linda Sapochak, Richard Russell, James A. Warren, Douglas Wells
Over the past decade, a consistent theme in enhancing U.S. global competitiveness has been the need for U.S. leadership in critical advanced manufacturing technologies. Additive manufacturing (AM), also known as 3D Printing, has been among those critical

Effects of local processing parameters on microstructure, texture, and mechanical properties of electron beam powder bed fusion manufactured Ti-6Al-4V

August 27, 2022
Author(s)
Edwin Schwalbach, Jake Benzing, Vikas Sinha, Todd Butler, Adam Pilchak, Kevin Chaput, Norman Schehl, Reji John, Nik Hrabe
Electron beam powder bed fusion scan strategies for parts or part groupings of various sizes and scan line lengths have been found to inadvertently lead to significant variations in crystallographic texture and mechanical properties for Ti–6Al–4V. This

Schmid Factor Crack Propagation and Tracking Crystallographic Texture Markers of Microstructural Condition in Direct Energy Deposition Additive Manufacturing of Ti-6Al-4V

July 6, 2022
Author(s)
Alec Saville, Jake Benzing, Sven Vogel, Jessica Buckner, Collin Donohoue, Andrew Kustas, Adam Creuziger, Kester Clarke, Amy Clarke
Metallic additive manufacturing (AM) provides a customizable and tailorable manufacturing process for new engineering designs and technologies. The greatest challenge currently facing metallic AM is maintaining control of microstructural evolution during

Segmentation of Additive Manufacturing Defects Using U-Net

June 30, 2022
Author(s)
Vivian W. Wong, Max Ferguson, Kincho Law, Yung-Tsun Lee, Paul Witherell
Additive manufacturing (AM) provides design flexibility and allows rapid fabrications of parts with complex geometries. The presence of internal defects, however, can lead to the deficit performance of the fabricated part. X-ray computed tomography (XCT)
