Rapid Wafer-Scale Growth of Polycrystalline 2H-MoS2 by Pulsed Metalorganic Chemical Vapor Deposition

July 12, 2017
Author(s)
Berc Kalanyan, William A. Kimes, Ryan Beams, Stephan J. Stranick, Elias J. Garratt, Irina Kalish, Albert Davydov, Ravindra Kanjolia, James E. Maslar
High volume manufacturing of devices based on transition metal dichalcogenide (TMD) ultra-thin films will require deposition techniques that are capable of reproducible wafer-scale growth with monolayer control. To date, TMD growth efforts have largely

TOWARDS KNOWLEDGE MANAGEMENT FOR SMART MANUFACTURING

July 4, 2017
Author(s)
Shaw C. Feng, William Z. Bernstein, Thomas D. Hedberg Jr., Allison Barnard Feeney
The need for capturing knowledge in the digital form in design, process planning, production, and inspection has increasingly become an issue in manufacturing industries as the variety and complexity of product lifecycle applications increase. Both

Mobile Manipulator Performance Measurement Data

June 27, 2017
Author(s)
Roger V. Bostelman, YaShian Li-Baboud, Steven Legowik, Tsai H. Hong, Sebti Foufou
The National Institute of Standards and Technology, Intelligent Systems Division has collected data detailing the performance measurement of a mobile manipulator, i.e., an automatic guided vehicle (AGV) with onboard robot arm from two different

Method to Improve Point-Based Registration by Restoring Rigid-Body Condition

June 26, 2017
Author(s)
Marek Franaszek, Geraldine S. Cheok
The purpose of rigid-body registration is to find a rotation and translation which transforms one coordinate frame to another. The procedure requires measurement of common points (fiducials) in both frames. Noise and possible bias in the acquired locations

Integrating Finite Element Analysis with Systems Engineering Models

June 11, 2017
Author(s)
Jerome Szarazi, Axel Reichwein, Conrad Bock
In order to promote traceability, consistency, interoperability and better collaboration between systems engineering and Finite Element Analysis (FEA)-based simulation activities, we propose a tool-independent description of FEA models that integrates with

Smart manufacturing through a framework for a knowledge-based diagnosis system

June 9, 2017
Author(s)
Michael P. Brundage, Boonserm Kulvatunyou, Toyosi Ademujimi, Badarinath Rakshith
Various techniques are used to diagnose problems throughout all levels of the organization within the manufacturing industry. Often times, this root cause analysis is ad-hoc with no standard representation for artifacts or terminology (i.e., no standard

Towards a Robot Task Ontology Standard

June 8, 2017
Author(s)
Stephen B. Balakirsky, Craig I. Schlenoff, Sandro R. Fiorini, Signe Redfield, Marcos Barreto, Hirenkumar Nakawala, Joel L. Carbonera, Larisa Soldatova, Julita Bermejo-Alonso, Fatima Maikore, Paulo J. Goncalves, Elena D. Momi, S. Veera Ragavan, Tamas Haidegger
Ontologies serve robotics in many ways, particularly in describing and driving autonomous functions. These functions are built around robot tasks. The goal of a recently established international study group is to develop a knowledge representation that

ACCURACY DEGRADATION ANALYSIS FOR INDUSTRIAL ROBOT SYSTEMS

June 7, 2017
Author(s)
Guixiu Qiao, Brian A. Weiss
As robot systems become increasingly prevalent in manufacturing environments, the need for improved accuracy continues to grow. Recent accuracy improvements have greatly enhanced automotive and aerospace manufacturing capabilities, including high-precision

Building Connections through Standards Landscaping

June 7, 2017
Author(s)
Paul W. Witherell, Yan Lu
Standards are an essential part of how we do business, from communication, to establishing best practices, to achieving quality control. As commerce and technology continues to diversify, standards, and standard organizations, have become increasingly

Identification of machine tool geometric performance using on-machine inertial measurements

June 6, 2017
Author(s)
Gregory W. Vogl, Radu Pavel, Andreas Archenti, Thomas J. Winnard, Matlock M. Mennu, Brian A. Weiss, Alkan Donmez
Machine tools degrade during operations, yet accurately detecting degradation of machine components such as linear axes is typically a manual and time-consuming process. Thus, manufacturers need automated and efficient methods to diagnose the condition of

A System and Architecture for Reusable Abstractions of Manufacturing Processes

June 2, 2017
Author(s)
Alexander Brodsky, Mohan Krishnamoorthy, William Z. Bernstein, M. Omar Nachawati
In this paper we report on the development of a system for managing a repository and conducting analysis and optimization on manufacturing performance models. The repository is designed to contain (1) unit manufacturing process performance models, (2)

Channel Modeling and Performance of Zigbee Radios in an Industrial Environment

May 31, 2017
Author(s)
Mehrdad Damsaz, Derek Guo, Jeff Peil, Wayne Stark, Nader Moayeri, Rick Candell
In this paper we describe measurements of wireless propagation characteristics to develop path loss models in industrial environments. The models for path loss we develop are two-slope models in which the path loss is a piecewise linear relation with the

Automated Uncertainty Quantification Through Information Fusion in Manufacturing Processes

May 12, 2017
Author(s)
Saideep Nannapaneni, David Lechevalier, Anantha Narayanan Narayanan, Sankaran Mahadevan, Sudarsan Rachuri
Evaluation of key performance indicators (KPIs) such as energy consumption is essential for decision-making during the design and operation of smart manufacturing systems. The measurements of KPIs are strongly affected by several uncertainty sources such
