Quantifying Machining Process Inventories In Detailed Design

August 24, 2021
William Z. Bernstein, Till Boettjer, Deverajan Ramanujan
This paper quantifies machining process inventories based on commonly used techniques in various stages of the detailed design process. We investigate variabilities in process inventories between these techniques and their relation to manufacturing process

Visualizing Model-based Product Definitions in Augmented Reality

August 23, 2021
Teodor Vernica, Robert R. Lipman, William Z. Bernstein
Augmented reality (AR) technologies present immense potential for the design and manufacturing communities. However, coordinating traditional engineering data representations into AR systems without loss of context and information remains a challenge. A

Feasability and Performance Analysis of Automating Engineering Change Requests

August 18, 2021
Michael Sharp, Thomas D. Hedberg Jr., William Z. Bernstein, Soonjo Kwon
Engineering change is a non-value-added activity that happens as a product progresses through its lifecycle. Engineering change is a significant cost sink in many projects. While avoiding and mitigating the risk of change is the ideal approach, mistakes

Contextualized Filtering for Shared Cyber Threat Information

July 18, 2021
Athanasios Dimitriadis, Christos Prassas, Jose L. Flores, Boonserm Kulvatunyou, Nenad Ivezic, Dimitris Gritzalis, Ioannis Mavridis
Cyber threat information sharing is an imperative process towards achieving collaborative security, but it poses several challenges. One crucial challenge is the plethora of shared threat information. Therefore, there is a need to advance filtering of such

Integrating MTConnect and IndoorGML for Asset Monitoring and Indoor Navigation

July 16, 2021
Aaron M. Hanke, Teodor Vernica, William Z. Bernstein
Interoperability across emerging visualization modalities, including augmented reality (AR) and virtual reality (VR), remains a challenge with respect to industrial applications. One critical issue relates to the lack of standard approaches for

Defining requirements for integrating information between design, manufacturing, and inspection

May 11, 2021
Thomas D. Hedberg Jr., Michael Sharp, Toby M. Maw, Moneer Helu, Mostafizur M. Rahman, Swati Jadhav, James J. Whicker, Allison Barnard Feeney
Industry desires a digital thread of information that aligns as-designed, as-planned, as-executed, and as-inspected viewpoints. An experiment was conducted to test selected open data standards' ability to integrate the lifecycle stages of engineering

Merging Geospatial echnologies with cross reality in the context of smart manufacturing systems
