Representation of Heterogeneous Objects in ISO 10303 (STEP)

July 1, 2000
Author(s)
Lalit Patil, D Dutta, Amba D. Bhatt, Kevin K. Jurrens, Kevin W. Lyons, Mike Pratt, Ram D. Sriram
Solid modeling of objects forms an important task in design and manufacturing. Recent developments in the field of layered manufacturing have shown potential for the physical realization of heterogeneous (multi-material) objects. Thus, there is a need to

NIST's support of rapid prototyping standards

February 1, 1999
Author(s)
Kevin K. Jurrens
Recent activities and interactions with industry have suggested to the National Institute of Standards and Technology (NIST) that formal standards for rapid prototyping could stimulate the growth and advancement of the technologies involved. Standards

Standards for the rapid prototyping industry

January 4, 1999
Author(s)
Kevin K. Jurrens
This paper proposes that development of formalized standards for the rapid prototyping (RP) industry will help enable the continued growth and further advancement of RP technologies. Appropriate standards can provide common methods for measuring the

Evaluating the Performance of Rapid Prototyping/Rapid Manufacturing Systems

September 28, 1998
Author(s)
Richard L. Rhorer, Kevin K. Jurrens, Bradley N. Damazo
A method of fabricating and measuring simple part shapes to evaluate the performance of Rapid Prototyping (RP) systems is proposed in this report. These test shapes would include cylinders, rectangular bricks, cones, and other basic shapes. We propose a

Author(s)
Kevin K. Jurrens
Continued growth and acceptance of rapid prototyping (RP) will come only if the technology reaches a broader base of users. For this to happen, it must become easier for companies to measure the benefits of RP and justify its costs. Today, measuring the

Manufacturing Evaluation of Designs: A Knowledge-Based Approach

March 1, 1997
Author(s)
Ronald Giachetti, Kevin K. Jurrens
Manufacturing evaluation is performed with heuristics that are developed internally by the manufacturing experts in the company. Many of the existing manufacturing evaluation systems tely on highly specialized knowledge, extensive databases, and require a

Beyond Product Design Data: Data Standards for Manufacturing Resources

August 1, 1996
Author(s)
Kevin K. Jurrens, Mary B. Algeo, James E. Fowler
The benefits of industrial standards are well-known. They facilitate common markets, influence marketing patterns, and augment the operations of distributed enterprises. Standards for representing, using and exchanging manufacturing data, like standards

Modeling of Manufacturing Resource Information, Requirements Specification

March 1, 1995
Author(s)
Kevin K. Jurrens, James E. Fowler, Mary B. Algeo
This document presents the results of a focused effort to comprehensively identify the characteristics of a common representation of a limited set of manufacturing resources. The resources so characterized include milling and turning machine tools, cutting
