Software to Report Product and Manufacturing Information in QIF Files

December 4, 2019
Author(s)
Robert R. Lipman
The QIF PMI Report (QPR) software generates a spreadsheet from a Quality Information Framework (QIF) file containing Product and Manufacturing Information (PMI). QIF is a unified XML framework standard for computer-aided quality QIF systems, available free

Helping Robots Stay on Target

December 2, 2019
Author(s)
Elena R. Messina, Jeremy Marvel
For decades, many manufacturers have counted on robots to tirelessly produce parts of predictable quality. One of the key attributes of robots is their repeatability, which means that their tool tip will return to the same pre-programmed location with a

CHALLENGES IN REPRESENTING MANUFACTURING PROCESSES FOR SYSTEMATIC SUSTAINABILITY ASSESSMENTS - WORKSHOP ON JUNE 21, 2018

November 27, 2019
Author(s)
Arvind Shankar Raman, Dustin Harper, Karl Haapala, Barbara S. Linke, William Z. Bernstein, KC Morris
A workshop on Challenges in Representing Manufacturing Processes for Systematic Sustainability Assessments, jointly sponsored by the U.S. National Science Foundation, the U.S. National Institute of Standards and Technology, ASTM International, the American

On Practice and Theory of Constructive Composite Geometry and Topology

November 25, 2019
Author(s)
Thomas D. Hedberg Jr., Allison Barnard Feeney, Vijay Srinivasan
This paper synthesizes a theory from industrial best practices codified in recent standards. Recent editions of ASME and ISO standards codify the evolving industrial best practices in defining and modeling the information about products made from fibrous

Nestor: A Tool for Natural Language Annotation of Short Texts

November 1, 2019
Author(s)
Michael Brundage, Rachael Sexton
Nestor is a software tool that annotates natural language CSV (comma-separated variable) files, with a UTF-8 encoding, using a process called tagging [1]. The outputted annotated datasets (as either a CSV or .h5 file) can be used for different analysis
