DIMENSIONAL METROLOGY STANDARDS LANDSCAPE
This figure illustrates four main interfaces: CAD Geometry and Tolerance, Off-line Programming, CMM Execution Commands, and CMM Measurement Results Output. The applicable standards are: STEP, DMIS, I++DME, and DML. Who are the players in this effort and what are their roles? Metrology Interoperability Project Team of the Automotive Industry Action Group is central to this effort. It consists of users and vendors, working together to achieve interoperability of software and hardware in automated metrology, in order to reduce product development cycle time and reduce manufacturing costs. This group was not formed to compete with existing standards groups (such as the Dimensional Metrology Standards Consortium (DMSC)), but merely to keep an eye of the "big picture" … to be an "umbrella" group that oversees all the metrology interface standards efforts worldwide, The MIPT seeks to harmonize standards overlaps and fill in gaps where they exist. NIST - we advise, support, and perform tasks for this standards effort. We develop tests for verifying compliance of implementations to each standard (NIST's current activity has focused on the I++DME and DML standards). We perform detailed standards analysis, as requested by the industry. We maintain a metrology interoperability testbed at NIST in Gaithersburg, MD, that is actually part of a distributed testbed with active participants worldwide. NIST's role in this overall effort is critical to its success. International Association of CMM Manufacturers (IA.CMM)- The purpose of the Association is to support and to promote the interests of the world-wide industry of coordinate measuring machines technologies. It sponsors the I++DME Team, which develops and maintains the I++DME Specification. Dimensional Metrology Standards Consortium (DMSC) - The DMSC grow out of the DMIS National Standards Committee (DNSC) and the DMSC has assumed responsibity for the maintenance and support of the DMIS Standard. However, the new mission of this group has expanded to address the development of other dimensional metrology standards. European DMIS Users Group - (EDUG) Chairman: Lutz Karras (Carl Zeiss), Vice Chair: Marcel Lenher (Metromec), Secretary: Gerd Becker (DaimlerChrysler). Recent activities in dimensional metrology interoperability IMTS 2004 demonstration of interoperability: NIST and several vendors demonstrated product interoperability of the I++DME and DML interfaces at the 2004 IMTS Show . Read the NIST trip report* (pdf). View the booth posters, Posters 1, Posters 2, Posters 3. Quality Expo 2005 and Control 2005 demonstrations of interoperability: NIST and several vendors demonstrated product interoperability of the I++DME and DML interfaces at these important trade shows. The functionality of these demonstrations was substantially expanded from that performed in the IMTS 2004 demonstration. Read the NIST trip report* (pdf).
