Implementing the ISO 15746 Standard for Chemical Process Optimization

July 3, 2016
Author(s)
Guodong Shao, Peter O. Denno, Albert T. Jones, Yan Lu
Integrating advanced process control solutions with optimization (APC-O) solutions, within any factory, enables more efficient production processes. Currently, vendors who provide the software applications that implement control solutions are isolated and

Technical Data Packages (TDPs) from the Smart Manufacturing Systems (SMS) Test Bed

July 1, 2016
Author(s)
Thomas D. Hedberg, Moneer M. Helu, Allison Barnard Feeney
Data is collected from the Manufacturing Lab using the MTConnect standard. That data is aggregated and published internally and externally of NIST via web services. Three channels of data dissemination are available or becoming available from the SMS Test

Identifying uncertainty in Laser Powder Bed Fusion models

June 30, 2016
Author(s)
Felipe F. Lopez, Paul Witherell, Brandon Lane
A limitation frequently encountered in additive manufacturing (AM) models is a lack of indication about their precision and accuracy. Often overlooked, information on model uncertainty is required for validation of AM models, qualification of AM-produced

Survey of Research for Performance Measurement of Mobile Manipulators

June 30, 2016
Author(s)
Roger V. Bostelman, Tsai H. Hong, Jeremy A. Marvel
This survey provides the basis for developing research in the area of mobile manipulator performance measurement, an area that has relatively few research articles, as com-pared to other mobile manipulator research areas. The survey begins with a

Reusing Metamodels and Notation with Diagram Definition

June 28, 2016
Author(s)
Conrad E. Bock, Maged Elaasar
It is increasingly common for language specifications to separate visual forms (concrete syntax) from underlying concepts (abstract syntax), enabling languages to define multiple visual forms for the same underlying concepts, and for the same visual form

Framework for Standardization of Simulation Integrated Production Planning

June 15, 2016
Author(s)
Deogratias Kibira, Guodong Shao, Bjoern J. Johansson
Production planning is a complex problem that is typically decomposed into decisions carried out at different control levels. Production planning methods employed often assume a static environment; therefore, the plans developed may not be feasible if shop

Propagation of Error from Registration Parameters to Transformed Data

June 6, 2016
Author(s)
Mili Shah, Marek Franaszek, Geraldine Cheok
Methods to register two sets of data have existed for quite some time. However, these sets of data are rarely error-free. Consequently, any parameters obtained from a registration method will be affected by the error in the sets of data. Moreover, if these

Methods and Tools for Performance Assurance of Smart Manufacturing Systems

June 2, 2016
Author(s)
Deogratias Kibira, Katherine C. Morris, Senthilkumaran Kumaraguru
The emerging concept of smart manufacturing systems is defined in part by the introduction of new technologies that are promoting rapid and widespread information flow within the manufacturing system and surrounding its control. These systems can deliver

Test Methods for Robot Agility in Manufacturing

June 2, 2016
Author(s)
Anthony J. Downs, William S. Harrison, Craig I. Schlenoff
In today's world of fast-paced change and ever evolving technologies, there is constant pressure on manufactures for agile production. The need for customization and robustness require today's manufacturers to shift production goals quickly, and address

Recommendations for Autonomous Industrial Vehicle Performance Standards

May 31, 2016
Author(s)
Roger V. Bostelman
A workshop was held at the IEEE International Conference on Robotics and Automation, called: "Autonomous Industrial Vehicles: From the Laboratory to the Factory Floor." Nine research papers were presented followed by a discussion session summarized in this

TOWARDS BUSINESS PROCESS CATALOG FOR CLOUD-ENABLED SERVICE-ORIENTED ARCHITECTURES

May 31, 2016
Author(s)
Nenad Ivezic, Miroslav Ljubicic, Boonserm Kulvatunyou, Conrad Leiva, Scott Nieman, Zoran Marjanovic
Advances in cloud-enabled service-oriented architectures have caused a resurgence of industry interest in business process catalog as a vehicle for establishing shared references for collaborative business processes. With this paper, we start to explore

Understanding sustainability data through unit manufacturing process representations: a case study on stone production

May 24, 2016
Author(s)
Bjoern J. Johansson, Mahesh Mani, William Z. Bernstein, Kevin W. Lyons, KC Morris, Laurie Rebouillat, Ilaria Barletta
Efficiency of natural stone production processes in quarries directly affects the economic output and environmental performances, such as production lead times and energy consumptions. Knowledge on stone production processes is crucial in making

Thermography and Weld Strength Characterization of Thermoplastic Extrusion 3D Printing

May 23, 2016
Author(s)
Jonathan E. Seppala, Kaitlyn E. Hillgartner, Chelsea S. Davis, Kalman D. Migler
In fused filament fabrication (FFF), a material extrusion additive manufacturing (AM) method, thermoplastic filament is extruded though a rastering nozzle on prior layers building a 3 dimensional object. The resulting strength of the FFF produced part is

Multiple Sensor Detection of Process Phenomena in Laser Powder Bed Fusion

May 20, 2016
Author(s)
Brandon M. Lane, Eric P. Whitenton, Shawn P. Moylan
Laser powder bed fusion (LPBF) is an additive manufacturing (AM) process in which a high power laser melts metal powder layers into complex, three-dimensional shapes. LPBF parts are known to exhibit relatively high residual stresses, anisotropic
