Leandro Buss Becker, Anthony Downs, Craig I. Schlenoff, Justin Albrecht, Zeid Kootbally, Angelo Ferrando, Rafael Cardoso, Michael Fisher
The ''Agile Robotics for Industrial Automation Competition'' (ARIAC) is an international robotic competition carried out in a simulated factory floor. ARIAC's competitors must perform assembly and kitting tasks by means of controlling four AGVs, one floor

Investigating the use of network analysis metrics to benchmark Industrial Symbiosis development

July 5, 2024
Author(s)
Abheek Chatterjee, Oren Minsk, Buddhika Hapuwatte, Matthew Triebe, Daniel Kietzer, Sushma Kittali-Weidner, KC Morris, Nehika Mathur
Circular economy (CE) aims to reduce natural resource consumption, waste generation, and related detrimental environmental, social, and economic impacts by keeping valuable materials circulating in the economy. Industrial Symbiosis (IS) contributes to CE

Integrated metrology for advanced manufacturing

Author(s)
andreas archenti, Wei Gao, Alkan Donmez, Enrico Savio, Naruhiro Irino
The transition from conventional standalone metrology to integrated metrology has been accelerating in advanced manufacturing over the past decade. This keynote paper defines the concept of integrated metrology, which extends beyond parts inspection and

An Interlaboratory Study for Assessing Repeatability and Reproducibility of the Data Generated by Rotating Drum Powder Rheometers Part 1: Granudrum

May 3, 2024
Author(s)
Vipin Tondare, Justin Whiting, Adam L. Pintar, Shawn P. Moylan, Aurelien Neveu, Filip Francqui
The National Institute of Standards and Technology (NIST) organized an interlaboratory study to assess the repeatability and reproducibility of the data generated by two commercially available rotating drum powder rheometers namely, Granudrum and

Decarbonizing the Economy: Circularizing Solar Photovoltaics

May 2, 2024
Author(s)
Nehika Mathur
Solar photovoltaics (PVs) are the fastest growing clean energy technology. As the first generation of solar PVs reach the end of their functional lives, it is becoming clear that unless strategies to manage discarded panels are implemented, we could be

Microstructural effects on the rotating bending fatigue behavior of Ti-6Al-4V produced via laser powder bed fusion with novel heat treatments

April 30, 2024
Author(s)
Nicholas Derimow, Jake Benzing, David Newton, Chad Beamer, Ping Lu, Frank DelRio, Newell Moser, Orion Kafka, Ryan Fishel, Lucas Koepke, Chris Hadley, Nik Hrabe
The rotating bending fatigue (RBF) behavior (fully reversed, R = -1) of additively manufactured (AM) Ti-6Al-4V alloy produced via laser powder bed fusion (PBF-L) was investigated with respect to different microstructures achieved through novel heat

Spatial and Temporal Data Alignment from Disparate Sources for Feature Association

April 25, 2024
Author(s)
Benjamin Standfield, Eric Holterfield, Russell Waddell
Among the chief topic areas of Industry 4.0, digital thread technology offers the opportunity for increased productivity, efficiency, and traceability throughout a product's lifecycle. While the basic concept of digital thread is easy to realize by

Evaluating Models That Predict Epoxy Conversion Using Rheological Properties

April 15, 2024
Author(s)
Stian Romberg, Paul Roberts, Chad R. Snyder, Anthony Kotula
Simultaneous rheology and conversion measurements of neat and composite epoxy resins reveal that conventional models neither accurately nor fully describe the relationship between rheology and conversion. We find that models predicting thermoset conversion

Author(s)
Jenny Martinez, Jenna Wardini, Xueli Zheng, Lauren Moghimi, Jason Rakowsky, Jonathan Means, Huiming Guo, Ivan Kuzmenko, Jan Ilavsky, Fan Zhang, Pratik Dholabhai, Leora Dresselhaus-Marais, William Bowman
Deploying energy storage and carbon capture at scale is hindered by the substantial endothermic penalty of decomposing CaCO3 to CaO and CO2, and the rapid loss of CO2 absorption capacity by CaO sorbent particles due to sintering at the high requisite

Exploiting the Digital Economy for Product Realization in Manufacturing

April 1, 2024
Author(s)
Paul Witherell, Soundar Kumara
In this paper we briefly discuss the evolving concepts of digital economy, digital threads, and product realization (manufacturing) in the digital economy enabled futuristic world. We posit that if we need to become self-sufficient, it is imperative that
