Simulating a Virtual Machining Model in an Agent-Based Model for Advanced Analytics

September 25, 2017
Author(s)
David J. Lechevalier, Seungjun Shin, Sudarsan Rachuri, Sebti Foufou, Yung-Tsun T. Lee, Abdelaziz Bouras
Monitoring the performance of manufacturing equipment is critical to ensure the efficiency of manufacturing processes. Machine-monitoring data allows measuring manufacturing equipment efficiency. However, acquiring real and useful machine-monitoring data

A DOMAIN DRIVEN APPROACH TO METAMODELING IN ADDITIVE MANUFACTURING

September 6, 2017
Author(s)
Peter O. Denno, Yan Lu, Paul Witherell, Sundar Krishnamurty, Ian Grosse, Douglas Eddy
Recent studies have shown advantages to utilizing metamodeling techniques to mimic, analyze, and optimize system input-output relationships in Additive Manufacturing (AM). This paper addresses a key challenge in applying such metamodeling methods, namely

Ionizing Radiation Processing and its Potential in Advancing Biorefining and Nanocellulose Composite Materials Manufacturing

September 1, 2017
Author(s)
Michael T. Postek, Dianne L. Poster, Andras Vladar, Mark S. Driscoll, Jay A. LaVerne, Zios Tsinas, Mohamad Al-Sheikhly
Nanocellulose is a high value material that has gained increasing attention because of its high strength, stiffness, unique photonic and piezoelectric properties, high stability and uniform structure. Through utilization of a biorefinery concept

Conceptual Modeling

August 19, 2017
Author(s)
Conrad E. Bock, Fatma Dandashi, Sanford Friedenthal, Natalie Harrison, Steven Jenkins, Leon McGinnis, Janos Sztipanovits, Adelinde Uhrmacher, Eric Weisel, Lin Zhang
Understanding and developing complex systems requires collaboration between individuals with widely varying expertise. Communication between these individuals is facilitated by conceptual models. Conceptual models are early stage artifacts that integrate

THERMAL PROPERTY MEASUREMENT METHODS AND ANALYSIS FOR AM SOLIDS AND POWDERS

August 9, 2017
Author(s)
Justin G. Whiting, Brandon M. Lane, Kevin Chou, Bo Cheng
Thermal properties of additive manufacturing (AM) solids and precursor materials are important factors for build process and part performance. However, measured thermal properties are not well documented, despite being used extensively in AM modeling and

INVESTIGATING GREY-BOX MODELING FOR PREDICTIVE ANALYTICS IN SMART MANUFACTURING

August 8, 2017
Author(s)
Peter O. Denno, Yan Lu, Paul Witherell, Sundar Krishnamurty, Ian Grosse, Douglas Eddy
This paper develops a grey-box modeling approach that combines manufacturing knowledge-based (white-box) models with statistical (black-box) metamodels to improve model reusability and predictability. A white-box model can utilize different types of

Modeling Performance Measurement of Mobile Manipulators

August 3, 2017
Author(s)
Roger V. Bostelman, Sebti Foufou, Tsai H. Hong
Mobile manipulators are being marketed around the world as single manufacturer systems (i.e., robot arm and vehicle manufactured by the same organization) and as independent robot arms, from a different manufacturer and integrated with automatic guided
