DML (Dimensional Markup Language)

The DML specification defines content and format for measurement nominals and actuals from a coordinate measuring machine.

The scope of this industry-led effort is on the exchange of dimensional measuring equipment commands and results between measurement execution software and a CMM.

NIST’s role is to 1) contribute to the writing of I++ DME, 2) generate conformance tests, 3) design and conduct public interoperability tests, and 4) act as standards consultants and leaders in industry standards organizations through summit meetings and other initiatives.

Industry Impact

• DML has been mandated within several large U.S. corporations, including Chrysler, GE Aviation, and John Deere
  
• For end users mandating DML, DML has allowed web-based access from any location to quality measurement results from CMMs located anywhere in the world, in real-time

Status

• An initial DML test utility has been designed and built by NIST
• AIAG published version 3.0
• DMSC and AIAG signed Memorandum of Agreement for DMSC to take DML to ANSI and then ISO
• DMSC has made substantial progress on DML and plans to take to ISO by 1st Quarter 2010

To-Do List

• DML test utility needs to be upgraded to current DML version
• Perform public interoperability tests at major quality technology shows
• Define and institute a DML certification program
