Metrology Interoperability Described
What is metrology interoperability? Having an interface language specification so defined and implemented that
users can interchange vendor implementations with minimal data reworking or translation or changes in vendor implementation
What is the challenge of metrology interoperability? Defining the interface appropriately, so that the vendors have all the functionality
they need, they have a lot of freedom to differentiate their product from the competition without revealing proprietary secrets, and the standards grow with changes in technology
What is metrology interoperability NOT? Equivalent measurement results, equivalent functionality
What is the goal of metrology interoperability? Working with and through major industry organizations (e.g., AIAG and I++),
develop and maintain common languages for the key interfaces…ensure that they are widely accepted and will enable interoperable systems with sufficient functionality
Who is involved? Users, vendors, industry organizations, and standards bodies

Metrology Interoperability Participants
Metrology Project Team 15
What is the role and perspective of vendors? Specification writing and implementation Naturally biased towards proprietary, but helped by interoperability
What is the role and perspective of users? Naturally desirous of interoperability, but often settles for proprietary Establish and communicate a business case internally Lead and participate in the standards development effort Ensure purchase requirements based on demonstrable conformance
What is the role and perspective of standards bodies (e.g., NIST)?
Test suite generation and specification analysis Facilitator, enabler, scribe, spokesperson, task leader Testbed development and maintenance
What is the role and perspective of industry organizations (e.g., AIAG and I++)?
Manage, advise, and facilitate efforts of working groups (e.g., MEPT) Provide resources and facilities for meetings Publish, disseminate, provide forum for specifications and other
documents
Metrology Interoperability Described
Metrology Project Team 16
What are the possible solutions to the interoperability problem?
Point-to-point, single vendor, common language
What is the preferred solution? Common languages for each interface
What are the problems and challenges of the common language solution?
Difficult to get everyone to agree, requires constant maintenance, can’t achieve 100% interoperability, vendors suspicious that they can’t achieve competitive edge if there is an open interface standard, etc.
What are the advantages of the common language solution?
Provides true interoperability, reduces costs (programming and training), since requires less time and effort, reduces measurement errors, provides greater freedom for 1) successful acquisitions, 2) best-in-class & individual preferences, 3) broader set of tailored metrology solutions, 4) integration and leverage with other domains, including electronics (NEMI), aerospace, and machine tools (OMAC)
Metrology Interoperability Described
Metrology Project Team 17
Why is it important and what is the benefit of metrology interoperability to me (whether a vendor, supplier, or OEM)?
Saves money, saves time, improves quality, facilitates technology advances (e.g., the PC), etc.
What would be the cost of involvement? Meeting attendance, AIAG membership, spec writing, spec
implementation, conference call meetings, leadership, testing, participation, etc.
Who should get involved and why? Anyone involved in automated dimensional metrology to save money and
time and to focus on other problems than code rewrite, etc.

Driving Metrology Interoperability
May 2000 Metrology Summit Major corporations met at NIST to identify problems
connecting metrology equipment within their extended enterprise.
They expressed frustration with their inability to implement an efficient process:
Inability to connect CAD / Simulation / metrology System Redundant Inspection Programs Inspection Program Portability Independent Quality plans Standards slow to develop Poor implementation of existing standards No oversight committee / no harmonization
What started this effort?
