Scalable Data Pipeline Architecture to Support the Industrial Internet of Things

May 17, 2020
Author(s)
Moneer M. Helu, Timothy A. Sprock, Daniel Hartenstine, Rishabh Venketesh, William Sobel
Managing manufacturing data remains challenging despite the growth of the Industrial Internet of Things (IIoT). While various standards and technologies enable greater access to data, scaling data processing and distribution can be difficult given the

Leveraging standard geospatial representations for industrial augmented reality

May 1, 2020
Author(s)
Teodor I. Vernica, Aaron M. Hanke, William Z. Bernstein
Due to its tremendous potential, Augmented Reality (AR) has experienced a recent surge in adoption and integration within the manufacturing enterprise. While industrial AR has been successfully implemented and shown to have significant benefits in a

Proceedings of the 11th Model-Based Enterprise Summit (MBE 2020)

April 30, 2020
Author(s)
Thomas D. Hedberg Jr., Mark G. Carlisle
The National Institute of Standards and Technology (NIST) hosted the eleventh installment of the Model-Based Enterprise Summit (MBE 2020) on March 31 through April 2, 2020 in Gaithersburg, Maryland. The MBE 2020 witnessed another year-over-year

Using Text Visualization to aid Analysis of Machine Maintenance Logs

April 30, 2020
Author(s)
Michael P. Brundage, Senthil K. Chandrasegaran, Xiaoyu Zhang, Kwan-Liu Ma
Maintenance and error logs for machines in manufacturing organizations are typically written as informal notes by operators or technicians working on the machines. These logs are written using a combination of common language and internally-used

FROM SCAN STRATEGY TO MELT POOL PREDICTION: A NEIGHBORING-EFFECT MODELING METHOD

April 23, 2020
Author(s)
Zhuo Yang, Yan Lu, Ho Yeung, Sundar Krishnamurty
The quality of AM built parts is highly correlated to the melt pool characteristics. Hence melt pool monitoring and control can potentially improve AM part quality. This paper presents a neighboring-effect modeling method (NBEM) that uses scan strategy to

Industry Review of Distributed Production in Discrete Manufacturing

April 18, 2020
Author(s)
Moneer M. Helu, William Sobel, Saigopal Nelaturi, Russell Waddell, Scott Hibbard
Distributed production paradigms have grown in discrete manufacturing as discrete products are increasingly made by global, distributed networks. Current challenges faced by discrete manufacturing, such as increased globalization, market volatility

Benchmarking Protocols for Evaluating Grasp Strength, Grasp Cycle Time, Finger Strength, and Finger Repeatability of Robot End-effectors

April 1, 2020
Author(s)
Joseph A. Falco, Daniel Hemphill, Kenneth E. Kimble, Elena R. Messina, Adam Norton, Rafael F. Ropelato, Holly A. Yanco
This paper describes a set of metrics and supporting benchmarking protocols for determining the performance characteristics of robot end-effectors. In the short-term, these tools are proving useful as a common ground for assessing and comparing end

Benchmarking Protocols for Evaluating Small Parts Robotic Assembly Systems

April 1, 2020
Author(s)
Kenneth Kimble, Joseph Falco, Elena R. Messina, Karl Van Wyk , Yu Sun, Mizuho Shibata, Wataru Uemura, Yasuyoshi Yokokohji
This paper presents a set of performance metrics, test methods, and associated artifacts to help progress the development and deployment of robotic assembly systems. The designs for three task board artifacts that replicate small part insertions and

Automatic Volumetric Segmentation of Additive Manufacturing Defects with 3D U-Net

March 23, 2020
Author(s)
Vivian W. Wong, Max Ferguson, Kincho Law, Yung-Tsun Lee, Paul Witherell
Segmentation of defects in additive manufacturing is challenging, due to the poor contrast, small sizes and variation in appearance of defects. Automatic segmentation can however provide quality control for additive manufacturing. Over recent years, 3D

A Graph Database Approach to Wireless IIoT Work-cell Performance Evaluation

February 28, 2020
Author(s)
Richard Candell, Mohamed T. Hany, Yongkang Liu, Karl R. Montgomery, Sebti Foufou
The work-cell is an essential industrial environment for testing wireless communication techniques in factory automation processes. A new testbed was recently designed and developed to facilitate such studies in work-cells by replicating various data flows

Defining Near-term to Long-term Research Opportunities to Advance Metrics, Models, and Methods for Smart and Sustainable Manufacturing

February 21, 2020
Author(s)
Arvind Shankar Raman, Karl Haapala, Kamyar Raoufi, Barbara S. Linke, William Z. Bernstein, KC Morris
Over the past century, research has focused on continuously improving the performance of manufacturing processes and systems - often measured in terms of cost, quality, productivity, and material and energy efficiency. With the advent of smart
