Design-for-Cost An Approach for Distributed Manufacturing Cost Estimation

September 2, 2019
Author(s)
Minchul Lee, Boonserm Kulvatunyou
Researches have shown that design changes cost more in later stages of product development. Therefore, companies adopt Design-for-X methods to optimize product designs from many aspects in the early design stage. Despite such efforts, they often encounter

Integrated Operations Management for Distributed Manufacturing

August 28, 2019
Author(s)
Timothy A. Sprock, Michael E. Sharp, William Z. Bernstein, Michael P. Brundage, Moneer M. Helu, Thomas D. Hedberg Jr.
In traditional manufacturing operations management systems, the four pillars of ISA-95 (production, quality, maintenance, inventory) are each implemented as separate software systems. Each system independently manages its own data, operational decision

Securing, Authenticating, and Visualizing Data-Links for Manufacturing Enterprises

August 26, 2019
Author(s)
William Z. Bernstein, Sylvere Krima, Laetitia Monnier, Mehdi Shahid
We introduce a prototype implementation of the Securing and Authenticating Data-Links (SADL) Interface, which interacts with a manufacturing handle registry to facilitate traceability of digital resources for engineering projects. This paper outlines the

A Standardized Representation of Convolutional Neural Networks for Reliable Deployment of Machine Learning Models in the Manufacturing Industry

August 18, 2019
Author(s)
Max K. Ferguson, Seongwoon Jeong, Kincho H. Law, Anantha Narayanan Narayanan, Svetlana Levitan, Jena Tridivesh, Yung-Tsun Lee
The use of deep convolutional neural networks is becoming increasingly popular in the engineering and manufacturing sectors. However, managing the distribution of trained models is still a difficult task, partially due to the limitations of standardized

TOWARDS EFFICIENT THERMAL SIMULATION OF POWDER BED FUSION ON PATH LEVEL

August 15, 2019
Author(s)
Paul W. Witherell
As a widely used additive manufacturing (AM) technology to produce metallic parts, powder bed fusion (PBF) is driven by a moving heat source. Thermal simulation is a critical tool to understand the mappings between manufacturing parameters (e.g. laser

Towards Operational Use of Unit Manufacturing Process Models

July 25, 2019
Author(s)
Amogh Kulkarni, William Z. Bernstein, David Lechevalier, Daniel Balasubramanian, Gabor Karsai, Peter O. Denno
Unit Manufacturing Processes (UMP) are models that capture succinct definitions of individual manufacturing steps in a manufacturing system. They are used to facilitate model composition and reuse. However, mainly due to their textual nature, they are

Where do we start? Guidance for technology implementation in maintenance management for manufacturing

July 23, 2019
Author(s)
Michael P. Brundage, Thurston B. Sexton, Melinda Hodkiewicz, Katherine C. Morris, Jorge Arinez, Farhad Ameri, Jun Ni, Guoxian Xiao
Recent efforts in Smart Manufacturing (SM) have proven quite effective at elucidating system behavior using sensing systems, communications and computational platforms, along with statistical methods to collect and analyze real-time performance data

WHERE DO WE START? GUIDANCE FOR TECHNOLOGY IMPLEMENTATION IN MAINTENANCE MANAGEMENT FOR MANUFACTURING

July 23, 2019

Michael P. Brundage, Thurston B. Sexton, Melinda Hodkiewicz, Katherine C. Morris, Jorge Arinez, Farhad Ameri, Jun Ni, Guoxian Xiao
Recent efforts in Smart Manufacturing (SM) have proven quite effective at elucidating system behavior using sensing systems, communications and computational platforms, along with statistical methods to collect and analyze real-time performance data

Integrating four-dimensional ontology and systems requirements modelling

July 18, 2019
Author(s)
Conrad E. Bock, Charles Galey
Ontology has many applications to engineering but is not easily taken up by engineers. For example, specifying products in space and time together (four dimensions) enables more reliable modelling and analysis, but this work is primarily ontological and

Complexity and Entropy Representation for Machine Component Diagnostics

July 9, 2019
Author(s)
Srinivasan Radhakrishnan, Yung-Tsun Lee, Sudarsan Rachuri, Sagar Kamarthi
The Complexity-entropy causality plane (CECP) is a parsimonious representation space for time series. It has two dimensions: normalized permutation entropy (Hs) and Jensen-Shannon complexity (Cjs) of a time series. The representation can be used for both

The Manufacturing Cost Guide: A Primer Beta Version 0.1

July 9, 2019
Author(s)
Douglas Thomas
This primer provides an overview in using the Manufacturing Cost Guide. It walks through the software tool and provides documentation on how the estimates are calculated in the tool. This tool estimates the costs in US manufacturing, which can be used to

The Unit Manufacturing Process (UMP) Builder: User's Guide

July 3, 2019
Author(s)
David Lechevalier, William Z. Bernstein
The ASTM E3012-16 Standard Guide for Characterizing Environmental Aspects of Manufacturing Processes provides guidelines for formally characterizing manufacturing processes. However, the difficulty that has arisen in the early use of the standard

Proceedings of the 10th Model-Based Enterprise Summit (MBE 2019)

July 2, 2019
Author(s)
Thomas D. Hedberg Jr., Mark G. Carlisle
The National Institute of Standards and Technology (NIST) hosted the tenth installment of the Model-Based Enterprise Summit (MBE 2019) on April 2-4, 2019 in Gaithersburg, Maryland. The MBE Summit grew 114 percent over the past five MBE Summits. This

IEEE RAS Standards Strategy Update

Author(s)
Craig I. Schlenoff
On September 30, 2018, the Industrial Activities Board (IAB) of the IEEE Robotics and Automation Society (RAS) organized a Standards Strategy Meeting in conjunction with the Intelligent Robots and Systems (IROS) Conference in Madrid, Spain. The goal of the

Bearing Metrics for Health Monitoring of Machine Tool Linear Axes

June 13, 2019
Author(s)
Gregory W. Vogl, Brian C. Galfond, Jordan Jameson
Diagnostics and prognostics of rotating machinery ball bearings is quite mature with an abundance of available methods and algorithms. However, extending these algorithms to other ball bearing applications is challenging and may not yield usable results
