The upcoming 2015 Coordinate Metrology Systems Conference (CMSC) will be held “beachside” this year in Hollywood, Florida, from July 20–24. Not only will you be able to swim in the beautiful Atlantic Ocean just steps away from the hotel, you will also be able to “swim” your way through the vast,…

Several years back, I was asked this question: Does measurement software have the ability to determine scale without the use of scale bars? On numerous occasions in a variety of ambient conditions, I have tested and compared the results of initially setting up a system using temperature/material…

Most manufacturing facilities have to manage the seemingly never-ending cycle of having to keep costs down while increasing production levels and maintaining high quality standards. Often, this ongoing struggle includes a reduction in staff and resources, and a lower-than-ever budget for…
The reconstruction of scenes from multiple images or video streams has become an essential component in many modern applications. Many fields, including robotics, surveillance, and virtual reality, employ systems to reconstruct a 3D representation of an environment in order to accomplish specific…

Ford Motor Co.’s Nondestructive Evaluation Laboratory (NDE) in Livonia, Michigan, is a leading facility for quality test inspection and failure analysis of automotive components. Historically, many of the automaker’s manufacturing programs depended heavily on coordinate measuring machines (CMMs)…
The use of optical 3D shape measurement devices are rapidly gaining importance, allowing the reconstruction of real 3D objects efficiently. The 3D shape and texture can be obtained from stereo images acquired with a freely moving camera. This approach measures the image displacement from the…

Finance professional Joe Fabiani never imagined his love of exotic cars would develop into a full-time career. It began when he searched for an improved exhaust for his Porsche 993 but was at a loss to find one that conformed to the specifications he had in mind. Frustration with OEM stock…

“So what’s the weather gonna do today?” I am sure that we have all been asked that after answering the first question (about what we do for a living) with: “Metrology.”
Metrology or meteorology? Both are studies of a particular science but are two words that are easily mistaken or misinterpreted…

Thanks to NASA’s Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside our solar system. The size of the exoplanet, dubbed Kepler-93b, is now known to an uncertainty of just 74 miles (119 km) on either side of the planetary…

What do you do when 20 ultra-rare violins from the 1730s show up in town, ready to be measured? Further, what exactly would you want to learn from these measurements? For many of us, the first thing that jumps to mind is, “Why do these particular instruments sound so much better than others of…

The Oasis of the Seas is the largest passenger ship in the world with a gross tonnage of 225,282 and room for more than 5,400 passengers. Not surprising, it creates a huge bow wave when sailing the seas and encounters waves of more than 60 ft when crossing the Atlantic Ocean.
When wave action…

With the 30th anniversary of the Coordinate Metrology Systems Conference (CMSC) around the corner, I am happy to celebrate World Metrology Week with you. This year’s conference will be held in North Charleston, South Carolina, from July 21–25, 2014. Charleston is the oldest and second-largest city…
Laser trackers and the software that controls them have revolutionized the way metrology data have been taken. With software and hardware advances have come new and better ways to take measurements. One of these advances in metrology software is the ability to measure the angle normal to a mirrored…

Hexapods: The word sounds alien, but we see them every day. A hexapod (“hexa” is the Greek word for six; “pod” is Greek for foot) is simply a spatial motion machine with six driving elements. They can be seen at fairgrounds, as the motor for carnival rides, or on flight simulators for pilot…

This article estimates the uncertainty for measuring a tool tip using dual Leica T-Mac sensors set up on opposite sides of an NC machine head and measured with tracking interferometers at opposite ends of a machine bed. Performance testing compares the estimated and measured uncertainties and…

They spanned 140 degrees of latitude—from Canada to Chile—and varied widely in age and experience. But their goal was the same: To improve their metrological capabilities for the benefit of their home countries and the Western Hemisphere.
For five extremely full days during the last week of…

Although 80 percent of Accurex’s business lies in the industrial application of precision metrology and scanning, the company always enjoys the occasional cultural heritage project. When the Accurex team was called upon to scan the Sphinx of Hatshepsut, it was ready for the…
The NOvA (NuMI off-axis νe appearance) experiment is looking to answer fundamental questions about neutrinos and the role they play in the universe. NOvA will use two detectors, a near detector located underground at Fermilab in Batavia, Illinois, and a far detector located 810 km from Fermilab…

For the Coordinate Metrology Society, CMSC 2013 will be recognized as a landmark year in its quest to provide state-of-the-art information and best practices to the metrology industry. Twenty-seven technical presentations were delivered at this conference, and I could not be more impressed with the…
