Interoperability and the DMIS experience

October 30, 2009
Author(s)
John A. Horst
Because they enable true interoperability, information exchange standards can help manufacturers reduce cost and improve product quality, but only if the standards are developed and implemented correctly. We will answer questions manufacturers and

Ontological Product Modeling for Collaborative Design

October 30, 2009
Author(s)
Conrad E. Bock, XuanFang Zha, Hyo W. Suh, Jae H. Lee
This paper presents a product modeling language for collaborative design that has the benefits of ontology and expanded capabilities in conventional product modeling. The proposed approach uses ontology to increase flexibility and accuracy in combining

John L. Michaloski, Byeong Eon Lee, Frederick M. Proctor, Sid Venkatesh, Sidney Ly
In the CNC manufacturing world, the continuing pressure to reduce costs and improve time to market places a premium on smarter ways of manufacturing and intensifies the need to integrate feedback from the shop floor into the enterprise business systems

STEP in a Nutshell

September 29, 2009
Author(s)
Thomas R. Kramer, Xun Xu
This chapter gives an overview of STEP, assuming that the reader may not be familiar with STEP. The chapter gives a short example of an industrial use of STEP. Then it touches briefly on the history and objectives of STEP, followed by the organization of

Formal Representation of Product Design Specifications for Validating Product Designs

August 27, 2009
Author(s)
Alex Weissman, Satyandra K. Gupta, Xenia Fiorentini, Sudarsan Rachuri, Ram D. Sriram
Large scale distributed design projects increasingly result in designs that do not fully conform to the stated design goals or specifications. Hence, there is a need to validate these designs against various requirements. For projects with a large set of

STEP-OAGIS Harmonization Joint Working Group, PDM Subgroup Interim Report

August 27, 2009
Author(s)
Xenia Fiorentini, Sudarsan Rachuri
In any manufacturing enterprise, there are two types of tools used to create and share product related data across its extended network. The engineering information of the product is created using what is commonly called engineering authoring tool (e.g

Documenting and Implementing Guidelines with Schematron

August 26, 2009
Author(s)
Joshua Lubell
Data exchange specifications must be broad and general in order to achieve acceptance, yet they must also be customizable in a controlled and interoperable manner in order to be useful. This paper describes an approach employing the Schematron language and

System Builders Manual for Version 2.1.5 of the NIST DMIS Test Suite

August 19, 2009
Author(s)
Thomas R. Kramer, John A. Horst
This is a system builders manual for the NIST DMIS Test Suite, version 2.1.5. The purpose of the manual is to help system builders use software provided in the test suite for building systems that implement DMIS (the Dimensional Measuring Interface

Towards a Method for Harmonizing Information Standards

August 19, 2009
Author(s)
Xenia Fiorentini, Sudarsan Rachuri, Steven R. Ray, Ram D. Sriram
Designers and engineers use various engineering authoring tools, such as CAD, CAE, and PDM,, to generate information objects (engineering objects). On the business side, enterprise level business process modelers use various business authoring tools, such

Performance of a Nanopositioner Controller Filter Compensator

August 12, 2009
Author(s)
Donna Le, Nicholas Dagalakis, Jason J. Gorman, Jae M. Yoo
We describe the use of appropriate type simple resistor and capacitor (RC) compensators, which properly connected to a power amplifier, can improve the dynamic performance of MEMS nanopositioners. Research on compensators led to the design of several

July 9, 2009
Author(s)
Katherine C. Morris, Joshua Lubell, Salifou Sidi Malick
Manufacturing industry is facing an enormous challenge today in trying to integrate a wide range of systems. The systems span the functional areas of manufacturing, as well as, the multitude of organizations and countries involved in the manufacture of

Semantic-Mediation for Standards-based B2B Interoperability

June 15, 2009
Author(s)
Marko Vujasinovic, Nenad Ivezic, Boonserm Kulvatunyou, Edward J. Barkmeyer Jr., Michele Missikoff, Francesco Taglino, Zoran Marjanovic, Igor Miletic
The authors discuss a semantic-mediation architecture to advance traditional approaches for standards-based business-to-business (B2B) interoperability. The architecture is supported by the ATHENA Knowledge Representation and Semantics Mediation tool suite

Service Oriented and Orchestrated Framework for Supply Chain Integration

June 8, 2009
Author(s)
Jack C.P. Cheng, Kincho H. Law, Albert T. Jones, Ram D. Sriram
Supply chain management integrates key business processes and facilities, involving end users and suppliers that provide products, services and information. Supply chain integration can potentially add value to the stakeholders along product development

Test Tool for Industrial Ethernet Network Performance

June 5, 2009
Author(s)
James D. Gilsinn, Freemon Johnson
The number of devices that implement Ethernet interfaces on the factory floor is growing at an exponential rate along with the adoption of industrial-grade Ethernet networks on the plant floor. In addition to the sheer number of devices using industrial
