The Coordinate Metrology Systems Conference is the only U.S. show dedicated to large-scale 3-D measurement.
Dirk Dusharme Published: 07/14/2009
Investing in capital equipment always involves an analysis of the return on investment (ROI), but never as much as during a recession. The question this year is often, "Our company is already tightening its belt, is this equipment going to help us save a lot of money in a relatively short time frame?" As reported in Quality Digest Daily, the market for large-scale 3-D metrology equipment could pick up in 2009, but a lot of that hinges on buyers having a clear understanding of the equipment’s ROI and 3-D equipment manufacturers doing a good job of communicating cost vs. benefit.
There is no event in the United States better situated to communicate the value and ROI of large scale 3-D metrology than the Coordinate Metrology Systems Conference. This year’s CMSC, its 25th, will be held in Louisville, Kentucky, July 20–24. It is the only show dedicated specifically to large-scale 3-D measurement equipment and software.
Quality Digest has been the media partner for the CMSC for five years. "The reason we got involved, and what we think makes the CMSC stand apart from other trade shows, is its emphasis on information sharing," says Mike Richman, publisher of Quality Digest Daily. "Because the show is relatively small by trade show standards—last year’s show had about 600 attendees—show organizers and exhibitors concentrate on giving attendees as much time and information as possible to help them understand which 3-D measurement solution is best."
The heart of the CMSC are the technical presentations, which provide 3-D solutions in action—everything from photogrammetry and laser trackers, to articulating arms and structured white-light scanners. These are rarely sales pitches for one technology. Because the issues involved in large-scale 3-D measurement are complex, presentations often focus on how multiple 3-D equipment, often from different vendors, can be used to solve unique 3-D measurement problems.
Some of the white papers’ content scheduled to be presented at this year’s conference include:
• Ambient testing of the James Webb Space Telescope using a laser tracker and laser radar
• Measurement-assisted assembly for large-volume aircraft wing structures
• Volumetric error compensation—innovative methodology for large machine-tool calibration
• The measurement of the USS Monitor’s XI-inch Dahlgren gun
• Geometry inspection of precision-forged crank shafts based on optical multisensor techniques
White papers presented at the CMSC during the past four years have been collected in the semiannual publication, The Journal of the CMSC, copies of which will be available at this year’s show. Quality Digest is proud to help edit and produce this in-depth presentation of the CMSC white papers. The next issue of The Journal of the CMSC, based on some of the papers presented during the 2009 conference in Louisville, will be offered to selected readers of Quality Digest Daily later this summer; if you’ re not on the distribution list, visit www.cmsc.org to learn how to get your own copy. You can also visit the CMSC web site for information about how to join the CMS Society, or even register for the conference—if you hurry.
We look forward to seeing you in Louisville. Be sure to stop by booth No. 609, where you’ll find the Quality Digest Daily team. We’re proud to support the Coordinate Metrology Society—the user group that runs the CMSC.
Following you’ll find a complete list of all exhibiting vendors.
