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

Developing a capability-based similarity metric for manufacturing processes

June 7, 2017
Author(s)
Kevin Li, William Z. Bernstein
Manufacturing taxonomies and accompanying metadata of manufacturing processes have been catalogued in both reference books and databases online. However, such information remains in a form that is uninformative to the various stages of the product life

BUSINESS PROCESS MODEL LIFE-CYCLE MANAGEMENT IN CLOUD MANUFACTURING

June 4, 2017
Author(s)
Miroslav Ljubicic, Nenad Ivezic, Boonserm Kulvatunyou, Scott Nieman, Nenad Anicic, Zoran Marjanovic
Business processes will play an important role in the realization of sustainable service-oriented manufacturing (SOM). In this paper, we propose a business process catalog to support that role. Such a catalog can facilitate both the life-cycle management

Dynamic Metrology and ASTM E57.02 Dynamic Measurement Standard

May 2, 2017
Author(s)
Roger V. Bostelman, Tsai H. Hong, Steven A. Legowik, Mili Shah
Optical tracking systems are used in a wide range of fields. The market for optical tracking systems has dramatically increased over the past several years to $1.2B revenue in 2014. This paper describes the new ASTM E3064 Standard test method procedures

This report summarizes the results from the OAGi/NIST workshop Drilling down on Smart Manufacturing -- Enabling Composable Apps, which was held at the National Institute of Standards and Technology campus in Gaithersburg, MD, on April 18-19, 2016. The

Design for Powder Bed Fusion of Metal Parts

April 1, 2017
Author(s)
Paul Witherell
Advancements in metals-focused technologies have taken 3D printing from a prototyping technology to an advanced, additive manufacturing (AM) production technology having a roadmap for even greater advancements [1].Most of today's commercially available

STEP File Analyzer Software

March 30, 2017
Author(s)
Robert R. Lipman
The STEP File Analyzer is a software tool that generates a spreadsheet or CSV files from a STEP (ISO 10303 –STandard for Exchange of Product model data) Part 21 file. STEP files are used to represent product and manufacturing information (PMI) and for data

Guideline for Automatic Guided Vehicle Calibration

March 2, 2017
Author(s)
Steven Legowik, Roger V. Bostelman, Tsai H. Hong, Elena R. Messina
This report documents the steps followed to calibrate an all-wheel steer Automatic Guided Vehicle (AGV) for optimal performance. Proper calibration of the steering and drive parameters of an AGV are critical for accurate dead-reckoning navigation, and

A Classification Scheme for Smart Manufacturing Systems Performance Metrics
