My main objective is to encourage greater use of statistical techniques in the service sector and present new ways to implement them.
In a previous blog, I presented an approach you can use to identify process steps that may be improved in the service sector (quartile analysis). here I’ll show…

In part 1 and part 2 of this series, we looked at the numbers of parts, operators, and replicates used in a gauge repeatability and reproducibility (GR&R) study and how accurately we could estimate %Contribution based on the choice for each. In doing so, I wanted to provide you with valuable…

Calibrating measurement and test equipment (M&TE) is expensive, but using equipment that is out of calibration can be even more costly. Faulty M&TE will produce suspect parts, and once you've discovered that your M&TE is the problem, you’ll have to screen the suspect parts and repair…

In part one of this series, I looked at how adequate a sampling of 10 parts is for a gauge repeatability and reproducibility (GR&R) study and provided some advice based on the results.
Now I want to turn my attention to the other two factors in the standard gage (or gauge, if you prefer)…

You take 10 parts and have three operators measure each part two times. This standard approach to a gauge (or gage, if you prefer) repeatability and reproducibility (GR&R) experiment is so common, so accepted, so ubiquitous that few people ever question whether it is effective.
Obviously one…

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…
NIST
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…

Metrologists are often faced with measurement processes that are repetitive and time-consuming. It’s not uncommon for a set of measurements to be taken repeatedly under different conditions and with different materials to maintain quality control. Afterward, the measurements must be formatted and…

Welcome to the winter edition of CMSC World. I want to touch on one of our biggest accomplishments of 2013—the Level-One Certification Program for Portable 3D Metrology. This program was requested and supported by many CMSC members. With your help and the tireless work of the Coordinate Metrology…

Innovative technologies, mobility, and flexibility in measurement technology are playing a major role for more and more companies. In addition to fixed coordinate measuring machines (CMMs) or traditional measurement arms, optical systems are increasingly becoming established in measurement…

PowerPoint is the devil’s instrument, and when you use it, you risk becoming a musician in his demonic orchestra. All of us are required to give presentations in some form or fashion at various points in our careers. If you’d like to succeed in those efforts, there are three things you should never…

Like so many other business software applications, calibration management software has evolved from simple beginnings as a digital index-card system that reminded operators when their instrument and tool calibrations were due. During the past 25 years, these systems have matured and are more…

Wood Stone Corp. captured American’s love for high-quality pizza and many other dishes when it started its stone-hearth cooking equipment business, eventually becoming world-renowned and the leading manufacturer in the industry. The company is especially popular for its wood-fired oven used by…

MIT engineers have devised a way to measure the mass of particles with a resolution better than an attogram—one millionth of a trillionth of a gram. Weighing these tiny particles, including both synthetic nanoparticles and biological components of cells, could help researchers better understand…

International standards ISO 6892 and JIS Z2241 for tensile testing of metallic materials have been revised with the addition of another test item: strain rate control.
When strain is measured with an extensometer, strain rate control has been added as a test item to the current stress rate…

The National Institute of Standards and Technology (NIST) has developed prototype calibration tools for an experimental medical imaging technique that offers new advantages in diagnosing and monitoring certain cancers and possibly other medical conditions.1
NIST designed, constructed and tested…

For the dreamer, high-tech enthusiast, and entrepreneur, 3D printing, also known as additive manufacturing, seems to embody the promise of what could be. Forward-thinking companies like Ford Motor Co., GE, and Mattel have been using 3D printing for R&D since the 1980s. However, the caveats…

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…

Creaform Inc., developer of the Handyscan 3D laser scanner, was recently acquired for approximately $120 million by AMETEK Inc., a global manufacturer of electronic instruments and electro-mechanical devices.
Creaform was formed in 2002 in Lévis, Québec, Canada, near Québec City. In 2005, the…

The AFM Option for the ZEISS MERLIN series combines a high-end, atomic force microscope (AFM) with a scanning electron microscope (SEM) to produce in situ, high-resolution AFM measurements in the SEM. The combination opens up new possibilities for characterizing nanostructures.
With the AFM,…

Last month, we started talking about data with the focus mainly on data management (aka data analysis) and only referencing data collection for a bit of context. Now I want to turn to data collection. Data collection is mostly about uncertainty (in this case “measurement uncertainty”) and more…

D ental erosion, a process that can cause demineralization and damage on dental substrate, is widely studied due to its high incidence within all age groups. Several techniques are used to analyze erosive lesions, including roughness measurement, profilometry, and morphological analysis of the…
