History of the DMIS Standard and The Dimensional Metrology Standards Consortium (DMSC, Inc.)
Written by Bailey Squier   
In 1983, an international consortium known at that time as Computer-Aided Manufacturing-International (CAM-I, Inc.) decided to initiate a Quality Assurance Interest Group for the purpose of investigating the benefits of research in the automation of Quality Assurance measurements and processes.  CAM-I sent out a “call” to more than one hundred companies, users and suppliers, requesting representatives to attend this Interest Group meeting.  The objective of the meeting was to decide if a CAM-I QA research program would be beneficial, and if so, what work should be undertaken.  Approximately 80 representatives attended that first meeting in 1983, each with their own list of concerns and woes related to QA.  The meeting was very productive as the group produced a list of more than 50 key issues that should be addressed within the Quality Industry.  The issues were prioritized by vote, and narrowed down to 35 on the first pass.  Several more rounds of redefining, discussions, and voting narrowed the list to the 10 top issues.  The highest, most urgent issue on the list was the development of a “common communication language between automated inspection systems.”  The intention from the very beginning was to make this language an official standard, a language that could be man-readable-and-writable, and could even be used as the internal language for the CMM Controller.  Thus the CAM-I Quality Assurance Program (QAP) was born.

The NIST DMIS Test Suite Can Work for You
Written by T. Kramer   
ABSTRACT
The NIST DMIS Test Suite 2.1.5 for DMIS version 5.1 is available. The test suite contains executable parsers for full DMIS (Dimensional Measuring Interface Standard) and three subsets of DMIS (called conformance classes). The three conformance classes are the three levels of the Prismatic Application Profile. Parsers are included for Linux, SunOS, and MS Windows operating systems. The Test Suite also includes hundreds of DMIS test files. The most recent version of the Test Suite (not the earlier versions) contains C++ source code that can reduce significantly the amount of work needed to build a software system that generates or consumes DMIS input files. A Users Manual and a System Builders Manual are included in the Test Suite. NIST is the National Institute of Standards and Technology.

Update on DMIS Certification
Written by Bill Rippey, NIST   
The Dimensional Standards Consortium (DMSC) and the National Institute of Standards and Technology (NIST) announced the rollout of the DMSC’s DMIS Certification Program at the International Manufacturing Technology Show (IMTS), in September 2008. The announcement was accompanied by a demonstration of the exchange of DMIS-compliant measurement programs from three competing metrology suppliers, each programming and executing the same DMIS level 2 prismatic measurement task on two CMMs in the booth. The certification process is a step in ensuring that the output of one vendor’s product can be successfully input and executed by the product of another vendor.  The benefits to users of DMIS products are savings of time and money, enabled by effortless interoperability of DMIS programming and execution products from different vendors.

The Dimensional Markup Language Specification for Inspection Results Data
Written by Bill Rippey, NIST   

The Dimensional Markup Language (DML) specification defines a data model and Extensible Model Language (XML) encoding rules for dimensional measurement results for discrete parts.  To support manufacturing quality assurance processes, DML results files are conveyed, typically from coordinate measuring machines (CMMs), to analysis, reporting, and database applications.  Coordinate Measuring Machine (CMM) execution software writes DML–compliant information, and measurement reporting and analysis software reads DML-compliant information.

User’s Must Drive Their Business Needs to Providers
Written by Ray Admire   
I entered the metrology industry in 1985 and have worked with all types of measurement systems. Manual and CNC CMM’s, Theodolites, Photogrammetry, Laser Trackers, vision systems. You name it and I have worked with it to some extent. As an end user for twenty-four years I can assure you that technology will continue to mature and progress and if we as users don’t demand a standard, non-proprietary solution from our providers, then we have put our companies and supply chain at risk. Risk because we have seen many mergers and acquisitions over the past two decades. Although some of these have been fruitful for the end-users, software that does not meet the DMIS standard will not migrate to any other system and measurement plans generated with those proprietary software systems will drastically limit your migration from that system. The cost to progress from proprietary software will be very expensive.
