Research and Application of Machine Learning for Additive Manufacturing

October 1, 2022
Author(s)
Paul Witherell, Yan Lu, Ying Liu, David W. Rosen, Timothy Simpson, Charlie Wang
Additive manufacturing (AM) is poised to bring a revolution due to its unique production paradigm. It offers the prospect of mass customization, flexible production, on-demand and decentralized manufacturing. However, a number of challenges stem from not

Ball Screw Health Monitoring with Inertial Sensors

September 30, 2022
Author(s)
Vibhor Pandhare, Marcella Miller, Gregory W. Vogl, Jay Lee
In industrial applications, the mechanical wear on ball screw components can lead to a loss of positioning accuracy that reduces the operational reliability and reproducibility of production systems. Existing monitoring solutions are impractical for real

Jaeho Lee, Craig I. Schlenoff
The Robotics and Automation Society's (RAS) standards working groups continue to grow. Our current working groups are pursuing standards and guidelines in the following areas. - Autonomous Robots - Ethically Driven Nudging for Robotic, Intelligent and

Towards the Physical Reliability of 3D-Integrated Systems: Broadband Dielectric Spectroscopic (BDS) Studies of Material Evolution and Reliability in Integrated Systems

September 30, 2022
Author(s)
Papa Amoah, Joseph J. Kopanski, Yaw S. Obeng, Christopher Sunday, Chukwudi Okoro, Lin You, Dmirty Veksler
In this paper, we present an overview of our current research focus in developing non-destructive metrology for monitoring reliability issues in 3D-integrated electronic systems. We introduce a suite of non-destructive metrologies that can serve as early

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
