7 NIST Support for Dimensional Metrology Interface Standards
The “interoperability problem” System users cannot easily and cheaply build systems from components Component vendors have to support many different proprietary interface languages Measurement quality suffers The interoperability solution: concurrent development of Interface standards: Timely, unambiguous, sufficiently functional, and consensus-based Implementations: Timely, compliant, fully functional, interoperable, and performed by a critical mass of vendors worldwide Tests: Product must pass conformance and interoperability tests for purchase 28/04/2005 John Horst NIST

9 NIST Support for Dimensional Metrology Interface Standards
Provide leadership, analysis, consultation, and testing support; working through AIAG MIPT I++ & IA.CMM DNSC & EDUG Regular and frequent implementers meetings to ensure Compliant implementations Consistent, unified, and documented feedback to spec writers to ensure unambiguous and sufficiently functional spec 28/04/2005 John Horst NIST

10 NIST Support for Dimensional Metrology Interface Standards
Write test suites consisting of test cases, test utilities, test artifacts, and example code modules for enabling new implementations Public interoperability tests to further encourage compliant implementations and unambiguous spec 28/04/2005 John Horst NIST

11 I/F Standards Test Development
NIST Validation Testing Validation Testing Interoperability Testing Can this specification support what my software can do? Why aren’t our two implementations communicating well? Conformance Testing How do I need to augment my product to conform? How well does this vendor’s software conform to the standard? Specification Writers Software and Hardware Vendors

16 NIST Support for Dimensional Metrology Interface Standards
The Inspection Process Plan Interface Impact DMIS is implemented by a majority of CMM software vendors worldwide DMIS conformance classes defined The DMIS National Standards Committee (DNSC) approved NIST’s design for a DMIS conformance test suite and unanimously signed an appeal urging NIST support for conformance test generation The DNSC, EDUG, and I++ DME groups are making substantive progress towards harmonization with I++ DME 28/04/2005 John Horst NIST

20 NIST Support for Dimensional Metrology Interface Standards
The Dimensional Metrology Equipment Interface Impact Most of the key coordinate measuring machine (CMM) hardware and software vendors worldwide now have implementations of I++ DME and are using NIST test utilities Two new test suite versions released (bootstrapping implementations) CRADA partners Zeiss and Wenzel as well as Renishaw have announced I++ DME compliant products 28/04/2005 John Horst NIST

21 NIST Support for Dimensional Metrology Interface Standards
