In many manufacturing applications, autonomous robot action is guided by a perception system integrated with the robot. The quality of the acquired 3D data must be high to ensure smooth and uninterrupted execution of robotic tasks. Unfortunately, many

Toward a Standard Data Architecture for Additive Manufacturing

January 16, 2024
Author(s)
Shengyen Li, Shaw C. Feng, Alexander Kuan, Yan Lu
To advance the additive manufacturing (AM) technologies, R&D projects may evaluate new facilities and different processes that need a scalable data architecture to accommodate the progressing knowledge. This work introduces a data pedigree to enable the

Employing Word-Embedding for Schema Matching in Standard Lifecycle Management

December 29, 2023
Author(s)
Hakju Oh, Boonserm Kulvatunyou, Albert T. Jones, Tim Finin
Today, businesses rely on numerous information systems to achieve their production goals and improve their global competitiveness. Semantically integrating those systems is essential for businesses to achieve both. To do so, businesses must rely on

Picoliter Drop Deposition of SnO2 Nanoparticles onto Microsensor Platforms

December 14, 2023
Author(s)
Elvin Beach, Kurt D. Benkstein, Krenar Shqau, Christopher Montgomery, Patricia Morris, Stephen Semancik
Microhotplates produced by micromachining processes provide a robust substrate for miniaturized solid-state gas sensors; however, it can be challenging to locally deposit solution-suspended nanomaterials for sensing directly onto these small (≈ 100 µm), 3

Intelligent Flexible Manufacturing Cell

December 11, 2023
Author(s)
Ethan Hollingsworth, Eric Holterman, Allison Barnard Feeney
Designed around Industry 4.0 based digital technology, flexible manufacturing cells are envisioned to comprise a variety of machines capable of peer-to-peer communication, learning, and adaptation with the end goal of creating a standards-based, brand

Knowledge Management for Data Analytics in Additive Manufacturing

November 21, 2023
Author(s)
Yeun Park, Paul Witherell, Albert T. Jones, Hyunbo Cho
As a multi-staged digital manufacturing process, Additive manufacturing (AM) inherently benefits from data analytics (DA) decision-making opportunities. The abundance of data associated with the various observations and measurements taken throughout the

Cutting force estimation from machine learning and physics-inspired data-driven models utilizing accelerometer measurements

November 13, 2023
Author(s)
Gregory W. Vogl, Yongzhi Qu, Reese Eischens, Gregory Corson, Tony Schmitz, Andrew Honeycutt, Jaydeep Karandikar, Scott Smith
Monitoring cutting forces for process control may be challenging because force measurements typically require invasive instrumentation. To remedy this situation, two new methods were recently developed to estimate cutting forces in real time based on the

Annual Report on the U.S. Manufacturing Economy: 2023

November 2, 2023
Author(s)
Douglas Thomas
This report provides a statistical review of the U.S. manufacturing industry. There are three aspects of U.S. manufacturing that are considered: (1) how the U.S. industry compares to other countries, (2) the trends in the domestic industry, and (3) the

Enhanced strength of additively manufactured Inconel 718 by means of a simplified heat treatment strategy

October 27, 2023
Author(s)
Jake Benzing, Nicholas Derimow, Orion Kafka, Nik Hrabe, Philipp Schumacher, Don Godfrey, Chad Beamer, Priya Pathare, Jay Carroll, Ping Lu, Isaiah Trujillo, Frank DelRio
This study simplified the heat treatment route and reduced the post-processing burden for laser powder bed fusion IN718 (a nickel-based superalloy). The tailored route retained advantageous microstructures and improved tensile strength when compared to the

In situ Probing of Interfacial Roughness and Transient Phases During Ceramic Cold Sintering Process

October 15, 2023
Author(s)
Fan Zhang, Russell Maier, Igor Levin, Andrew J. Allen, Jun-Sang Park, Peter Kenesei, Ivan Kuzmenko, Jan Ilavsky, Pete Jemian
The ceramic cold sintering process (CSP) offers an eco-friendly approach to producing fully dense ceramics at low temperatures. However, an incomplete mechanistic understanding hinders its optimization and widespread adoption. In this study, we analyze the

Part Deflection Measurements of AM-Bench IN718 3D Build Artifacts

October 6, 2023
Author(s)
Maxwell Praniewicz, Jason Fox, Jared Tarr
One of the primary barriers for adoption of additive manufacturing (AM) had been the uncertainty in the performance of AM parts due to residual stresses/strains. The rapid melting and solidification which occurs during AM processes result in high residual

Towards Ontologizing a Digital Twin Framework for Manufacturing

September 21, 2023
Author(s)
Milos Drobnjakovic, Guodong Shao, Ana Nikolov, Boonserm Kulvatunyou, Simon P. Frechette, Vijay Srinivasan
This paper presents a timely opportunity to ontologize a digital twin frame-work for manufacturing using recently published international standards and proposes a collaborative research effort to accomplish this task. The ISO/IEC 21838 series of standards
