Is someone sitting upright in the passenger seat of the car or is that passenger bending over? Did someone enter the hazard zone in front of an industrial machine? Stretch and pressure sensors have a wide range of applications. Researchers have now developed sensors capable of expanding, in…
Tracker Handbook by Art Kietlinski
During the past 30 years I’ve had the opportunity to measure quite a few manufactured parts, machine tools, fabrications, and large vessels. I’ve also reviewed hundreds of metrology surveys done by technicians. Unfortunately, on more than one occasion I’ve seen data that were scaled incorrectly…

The web is buzzing about Nokia’s Ovi Maps—and rightly so. The new 3-D interface the company has debuted, which allows you to take amazing 3-D fly-throughs of some of the world’s most beautiful cities, is a revelation. If you haven’t played with it yet, do so now by clicking here and wasting a…

Air gauging relies on a law of physics that states flow and pressure are directly proportionate to clearance and react inversely to each other. As clearance increases, air flow also increases, and air pressure decreases proportionately. As clearance decreases, air flow also…

Every once in awhile people will ask me to (discretely) evaluate a kaizen event team’s effectiveness. I don’t necessarily relish doing that when it is intended for the purpose of team comparisons, but it’s not an unfair request from senior leaders.
Someday, I should probably try to pull the…

We couldn’t pass this story up. Sure, this toy isn’t anywhere near as accurate as a Steinbichler or Capture3D or Breukmann or any of the others, but it is really cool.--Editors
Leave it to an iPhone app developer to turn a tool that cost hundreds of dollars a year ago into something that can be…

Test and measurement equipment play a critical role in most production and development processes. These instruments are used to make decisions regarding the effectiveness of processes and to ensure product quality. It is no surprise, therefore, that the need for regular calibration of test and…

TVL (Toeleveringsbedrijf van Landuyt) in Wetteren, Belgium, has been finishing transmission housings for wind turbines for the past several years. When the company began, production numbered about 2,000 housings, which doubled by 2008, and its annual capacity continues to grow with each passing…

The United Kingdom’s Channel 4 flagship television program Time Team, which has been uncovering the archaeological mysteries of the British Isles since 1994, has used 3-D laser scanning technology to create high-definition fly-through animations around Mont Orgueil Castle in Jersey.

Dutch company HGG specializes in steel profile cutting. It manufactures bevel-cutting machines particularly suited for processing large components. EEW, a German manufacturer of wind turbine components, placed an order with HGG. It needed to manufacture foundation structures (also…

Globally, wind power generation has increased more than fivefold since 2000. With the global trend toward limiting CO2 emissions and numerous governmental programs subsidizing or financing wind power generation, its share of global power generation is set to experience substantial growth in the…
Tracker Handbook by Art Kietlinski
As a senior applications engineer, one of my tasks is to train customers to correctly operate a laser tracker. This month, I would like to share with you some common in-field experiences and issues that I encounter with those who use a laser tracker on a day-to-day basis.
With more than 20 years…

On Jan. 29, 2004, 11 people lost their lives and 50 were wounded in a suicide bombing on Egged Bus 19 in Jerusalem. Since that tragic incident, the remains of Bus 19 have travelled around the world as a reminder of the horrors of terrorism. First stopping at The Hague for the International Court of…

In recent years, many airplane manufacturers have started building their planes from advanced composite materials, which consist of high-strength fibers such as carbon or glass, embedded in a plastic or metal matrix. Such materials are stronger and more lightweight than aluminum, but they are…

When teaching the I-chart, I’m barely done describing the technique (never mind teaching it) when, as if on cue, someone will ask, “When and how often should I recalculate my limits?” I’m at the point where this triggers an internal “fingernails on the blackboard” reaction. So, I smile and once…

Forty or 50 years ago, when you sat down in front of, or picked up, a dimensional measurement tool, you immediately recognized that a certain amount of knowledge and skill was required to use it. The measurement operation was almost always completely manual, and even reading and interpreting the…

The Georgia Tech Research Institute (GTRI) may possess the secret to baking perfect buns every time. Its researchers have developed a production-line system that automatically inspects the quality of sandwich buns exiting the oven and adjusts oven temperatures if it detects unacceptable buns…
