Creating quality coordinate measuring machine (CMM) measurement programs takes time, and production cycles are often delayed while waiting for the measurement programs to be created. But software that works directly from model-based definitions can drastically decrease that time.
The move from 2D…

I have heard people say that geometric dimensioning and tolerancing (GD&T) is a black art, and I agree—it can almost seem that way sometimes. My experiences in coordinate metrology throughout the past 20 years demonstrate a widespread lack of understanding, confusion, and even resentment for…

Right now I’m enjoying my daily dose of morning joe. As the steam rises off the cup, the dark, rich liquid triggers a powerful enzyme cascade that jump-starts my brain and central nervous system, delivering potent glints of perspicacity into the dark crevices of my still-dormant consciousness.…

One of the primary objectives of surface metrology research, functional correlation refers to the relationships between surfaces and the phenomena that influence or are influenced by their topography. Surface topography is also called texture, particularly in mechanical and manufacturing…

Smartphones and tablets are everywhere, which is great for communications but a growing burden on wireless channels. Forecasted huge increases in mobile data traffic call for exponentially more channel capacity. Boosting bandwidth and capacity could speed downloads, improve service quality, and…

Skeleton racing, a high-speed winter sliding sport, was born in Switzerland. The speeds achieved by racers hurtling down the track at more than 90 miles per hour would qualify them for a heavy fine for speeding on Switzerland’s motorways. “And not just that,” states Kristan Bromley, CEO of Bromley…

There are several methods for inspecting laser-drilled and electrical discharge machined cooling holes on aircraft engine turbine blades, vanes, nozzles, heat shields, and other similar parts. These holes are essential features of the cooling systems that protect critical components against the…
Nikon Metrology Inc.
Kiekert AG, the global leader for automobile door lock systems, now uses digital cross scanners by Nikon Metrology to test the positions and dimensions of sealing lips on door and rear compartment locks. Tactile inspection methods are unable to correctly measure these touch-sensitive and complex…

In the manufacturing industry, it is ideal to ensure high manufacturing accuracy without the need for inspection. In fact, however, the inspection and the measurement processes are performed for various reasons, such as to secure the product traceability, to visualize the quality of production,…
GE has introduced a metrology package for highly efficient, extremely precise 3D metrology performed with computed tomography (CT). The company states the enormous efficiency benefits, the use of industrial CT for nondestructive failure and structure analysis, and 3D metrology (especially for…

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,…
Ultrasonic thickness gauging is a widely used nondestructive test technique for measuring the thickness of a material from one side. It's fast, reliable, and versatile, and unlike a micrometer or a caliper it requires access to only one side of the test piece. The first commercial ultrasonic gauges…

I really can’t make this stuff up.
I wrote a post a couple of years ago titled: “How to Talk to Your Kids About... Quality Improvement,” in which I lamented about Community Hero Day in my daughter’s first-grade class and the need to explain to her why I wasn’t at the “community-hero level” of…
NIST
National Institute of Standards and Technology (NIST) researchers and their industrial partners aim to add a new dimension to manufacturing capabilities. In a new project, they will demonstrate the feasibility—and benchmark the advantages—of using standardized 3D models for electronically…

It’s a fact that air gauges are typically not in use approximately 90 percent (or more) of the time they’re in your shop or QC department. Because these gauges function by using clean and dry compressed air in a highly controlled flow, this relatively expensive commodity can cost your operation…

All manufacturing companies that get audited require some or all of their calibration certificates to specify the calibration uncertainty. At a minimum, some manufacturers only need certified uncertainty for gauges that are reference standards used to calibrate other gauges. Those companies…

When auto manufacturers set out to create award-winning vehicles, much consideration is given to interior sound quality. Ironically, the manufacturers have been so successful in mitigating road noise they have inadvertently caused a new problem for themselves: Apparently, the cars are too quiet.…

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…

Every manufacturing company that gets audited, anywhere in the world, is required to do gauge repeatability and reproducibility (R&R) studies. In some cases, this one study is the only chance to find unknown problems with measurement quality. (When problems do occur, it is often downstream…

The age of advanced digital microscopy is here—highly sophisticated image processing can now be performed with the same ease of use one would expect from a smartphone, tablet, or digital camera. Specifically designed for the needs of industrial QA/QC control labs, digital microscopes like the…

We all know what happens to a squeaky wheel, right? But just how loud does a wheel need to squeak before it’s squeak-worthy of replacement?
During my years of auto repair, one of the interesting tidbits I was hipped to was this: What human ears perceive as a squeak is actually a high-frequency…

Nondestructive testing (NDT), as the name implies, is a methodology used for examining the hidden internal structure, measuring the thickness, or characterizing the material of industrial parts without cutting or otherwise damaging them.
NDT offers important tools for ensuring both safety and…

Handan Iron & Steel Group (Han Steel) was established in 1958 in the Hebei province, China. The company is capable of producing up to 10,000,000 tons of steel annually and plays a vital role in China’s steel production. To maintain quality control in the production process, Han Steel relied on…
