Reusing and Extending Standards-based Unit Manufacturing Process Models for Characterizing Sustainability Performance

April 1, 2023

Author(s)

Arvind Shankar Raman, KC Morris, Karl R. Haapala

Over the past two decades numerous efforts have characterized manufacturing processes for sustainability performance. These efforts have been pursued primarily by manufacturing researchers in academic and governmental labs, and involve the development of

Three New IEEE Robotics and Automation Society Standards Working Groups on Surgical Robotics and Electric Vehicle Charging Robots

Solidification modes during additive manufacturing of steel revealed by high-speed X-ray diffraction

March 1, 2023

Author(s)

Hans-Henrik Konig, Niklas Hollander Pettersson, A Durga, Steven Van Petegem, Daniel Grolimund, Qilin Guo, Chihpin Chuang, lianyi Chen, Christos Oikonomou, Fan Zhang, Greta Lindwall

Solidification during fusion-based additive manufacturing (AM) is characterized by high solidification velocities and high thermal gradients, two factors that control the solidification mode of AM metals and alloys. Using two synchrotron-based, in situ

Digital Twin-Based Cyber-Attack Detection Framework for Cyber-Physical Manufacturing Systems

February 23, 2023

Author(s)

Efe Balta, Michael Pease, James Moyne, Kira Barton, Dawn Tilbury

Smart manufacturing (SM) systems utilize run-time data to improve productivity via intelligent decision-making and analysis mechanisms on both machine and system levels. The increased adoption of cyber-physical systems in SM leads to the comprehensive

On Migrating ISO 10303 PMI Models to a Common Core

January 4, 2023

Author(s)

Allison Barnard Feeney, Thomas Thurman

Industrial users of ISO 10303 STandard for the Exchange of Product Model Data (STEP) protocols needed the ability to exchange design product data that is in conformance with recently updated ISO geometric product specification (GPS) standards, the American

On the Fidelity of the Scaling Laws for Melt Pool Depth Analysis During Laser Powder Bed Fusion

December 27, 2022

Author(s)

Mehdi Naderi, Jordan Weaver, David Deisenroth, Nagaraja Iyyer, Raymond McCauley

In additive manufacturing, the part quality is highly dependent on process parameters. The morphology of the melt pool (depth and width) is highly affected by process parameter selection. Available scaling laws more or less overestimate or underestimate

Towards a Digital Twin of a Robot Workcell to Support Prognostics and Health Management

December 14, 2022

Author(s)

Deogratias Kibira, Brian A. Weiss

Current maintenance research often includes modeling the equipment degradation to determine degradation and in particular, when any degradation will exceed a specified threshold. Such models can provide critical intelligence to determine an impending

Textiles in a circular economy: An assessment of the current landscape, challenges, and opportunities in the United States

November 30, 2022

Author(s)

Kelsea Schumacher, Amanda L. Forster

The production and consumption of textile products traditionally follows a largely linear (take, make, use, discard) economic model. Textiles are currently being produced in greater volumes than ever before, even after accounting for population growth, and

Performance Measures to Benchmark the Grasping, Manipulation and Assembly of Deformable Objects Typical to Manufacturing Applications

November 21, 2022

Author(s)

Kenny Kimble, Justin Albrecht, Megan Zimmerman, Joseph A. Falco

The National Institute of Standards and Technology is developing performance tests and associated test artifacts as a means to benchmark research in the area of robotic assembly. Sets of components consistent with mechanical assemblies including screws

In-Process Data Integration for Laser Powder Bed Fusion Additive Manufacturing

November 11, 2022

Author(s)

Milica Perisic, Yan Lu, Albert T. Jones

Additive manufacturing (AM) is a powerful technology that can create complex metallic parts and has the potential to improve the economic bottom line for various industries. However, due to process instabilities, and the resulting material defects that

REPEATABILITY AND SENSITIVITY OF A ROTATING DRUM METHOD FOR RHEOLOGICAL CHARACTERIZATION OF STAINLESS STEEL POWDERS USED FOR ADDITIVE MANUFACTURING

November 6, 2022

Author(s)

Justin Whiting, Vipin Tondare, Shawn P. Moylan

There remains a need for rheological characterization of metal powder used for powder-spreading-based additive manufacturing (AM). Novel powder rheometers introduced to the commercial market for this purpose must be rigorously evaluated for repeatability
