November 18, 2016
Author(s)
Craig Blue, Larry Brown, Yoel Fink, Nick Justice, Michael Liehr, Tom McDermott, Ed Morris, Shawn P. Moylan
The Manufacturing USA program is composed of the collective of all of the manufacturing innovation institutes and a supporting Network. The Network serves the Institutes, the Institutes connect through the Network, and the Program serves the Nation.

Planning Algorithms for Multi-Setup Multi-Pass Robotic Cleaning with Oscillatory Moving Tools

November 17, 2016
Author(s)
Ariyan M. Kabir, Joshua D. Langsfeld, Shaurya Shriyam, Vinaichandra S. Rachakonda, Cunbo Zhuang, Krishnanand N. Kaipa, Jeremy Marvel, Satyandra K. Gupta
We describe planning algorithms for cleaning stains on a curved object. Removing the stain may require multiple reorientations of the part and some portions of the stain may require multiple cleaning passes. The experimental setup involves two robot arms

Sensor Calibration and Registration for Mobile Manipulators

November 16, 2016
Author(s)
Steven Legowik, Roger V. Bostelman, Tsai H. Hong
This paper describes the methods used to register a mobile manipulator to a workstation to perform assembly tasks. The nonlinear, least square model of the system is formulated and Ceres Solver[1] is used to compute the position of the robot arm relative

Fabrication, Testing and Simulation of All Solid State Three Dimensional Li-ion Batteries

November 10, 2016
Author(s)
Alec Talin, Dimitry Ruzmetov, Andrei Kolmakov, Kim McKelvey, N Ware, Farid El Gabaly, Bruce Dunn, Henry White
In this paper we demonstrate fully-functional 3D SSLIBs fabricated using materials and thin film deposition methods compatible with semiconductor device processing. These 3D SSLIBs consist of conical or cylindrical Si microcolumns onto which layers

Towards a generalized energy prediction model for machine tools

November 9, 2016
Author(s)
Raunak Bhinge, Jinkyoo Park, Kincho H. Law, David Dornfeld, Moneer Helu, Sudarsan Rachuri
Energy prediction of machine tools can deliver many advantages to a manufacturing enterprise, ranging from energy-efficient process planning to machine tool monitoring. Physics-based energy prediction models have been proposed in the past to understand the

A Tetherless, Absolute-Time Channel Sounder, Processing, and Results for a Complex Environment

November 4, 2016
Author(s)
David R. Novotny, Alexandra E. Curtin, Catherine A. Remley, Peter B. Papazian, Jeanne T. Quimby, Richard Candell
we present a channel sounder that can operate without a tether and still maintain an absolute time reference between the source and receiver. Based on a sliding correlator, with synchronized rubidium clocks to generate phase references for the up- and down

Towards a Road-Mapping Ontology for Open Innovation in Smart Manufacturing

October 30, 2016
Author(s)
Nenad Ivezic, Miroslav Ljubicic
In nascent areas, such as Smart Manufacturing, new collaborative research and development programs (R&D) are frequently formed with the goal to ignite the innovation lifecycle. Yet, clearly formulating common goals and enabling shared understanding of key

Review of Research for Docking Automatic Guided Vehicles and Mobile Robots

October 13, 2016
Author(s)
Roger V. Bostelman, Tsai H. Hong
This survey provides a literature review of docking research, an area that has relatively few research articles as compared to generic automatic guided vehicle (AGV) or mobile robot research. Docking refers to the arrival and act of a vehicle stopping at a

Non-contact Surface Conductance Measurement of Graphene using Resonant Cavity

October 10, 2016
Author(s)
Jan Obrzut, Oleg A. Kirillov
The measurement of conductance by a resonant cavity involves monitoring the resonant frequency shift and change in the quality factor before and after insertion of the specimen into the cavity. The method is applicable to carbon Vapor deposited (CVD)

Cyber-physical Systems Engineering for Manufacturing

October 7, 2016
Author(s)
Allison Barnard Feeney, Simon P. Frechette, Vijay Srinivasan
There is a convergence of interests in cyber-physical systems, systems engineering, and manufacturing innovation in the United States. The U.S. National Institute of Standards and Technology (NIST) has undertaken research programs in smart manufacturing

Inertial Measurement Unit for On-Machine Diagnostics of Machine Tool Linear Axes

October 7, 2016
Author(s)
Gregory W. Vogl, Alkan Donmez, Andreas Archenti, Brian A. Weiss
Machine tools degrade during operations, yet knowledge of degradation is elusive; accurately detecting degradation of machines' components such as linear axes is typically a manual and time-consuming process. Thus, manufacturers need automated, efficient

Measurement of powder bed density in powder bed fusion additive manufacturing processes

October 5, 2016
Author(s)
Gregor Jacob, M A. Donmez, Shawn P. Moylan, John A. Slotwinski
There are many factors influencing the additive manufacturing (AM) processes resulting in high degree of variation in process outcomes. Therefore, quantifying these factors and their correlations to the process outcomes are important challenges to overcome

An Activity Model for Factory Design and Improvement

October 4, 2016
Author(s)
Kiwook Jung, Sangsu Choi, Boonserm Kulvatunyou, Hyunbo Cho, Katherine C. Morris
Smart Manufacturing Systems (SMS) are envisioned to contain highly-automated and IT-driven production systems. To address the complexity that arises in such systems, a standard and holistic model for describing the activities and their inter-relationships

Annual Manufacturing Report

October 3, 2016
Author(s)
Douglas Thomas
The purpose of this report is to track domestic manufacturing activity and its supply chain in order to develop a quantitative depiction of U.S. manufacturing in the context of the domestic economy and global industry. This depiction provides change agents

STANDARD REPRESENTATIONS FOR CHARACTERIZATION OF INDUSTRIAL PROCESSES

October 1, 2016
Author(s)
Mahesh Mani, Jon Larborn, Bjoern J. Johansson, Kevin W. Lyons, Katherine C. Morris
This paper describes ASTM’s new guide for characterizing the environmental aspects of manufacturing processes (ASTM WK35705). The guide defines a generic representation to support structured information. Representations of multiple unit manufacturing

CHALLENGES IN TOLERANCE TRANSFER FOR ADDITIVE MANUFACTURING

September 22, 2016
Author(s)
Gaurav Ameta, Shawn P. Moylan, Paul Witherell
Abstract: From the design point of view, datum features are used to imply design intent of particular function of the part or sequence of assembly of components in a product. Each feature in a part could potentially have different datum reference based on
