Dimensional Metrology System with Standard Interfaces

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

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

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
Software and Hardware VendorsSpecification Writers
How well does this vendor’s software conform to the standard?
Why aren’t our two implementations communicating well?
How do I need to augment my product to conform?
Conformance Testing
Can this specification support what my software can do?

The Measurement Results Interface Impact
NIST CRADA partner, Mitutoyo, recently delivered a DML compliant product to GE Transportation; CRADA partners DCS, LK, and Tecnomatix have working products at Daimler Chrysler
Daimler Chrysler has performed tests with several other DML compliant products (Wilcox, Zeiss, Metrix, Cognitens, Capture3D)

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

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
