If you are a George Clooney fan you have probably seen the movie, “The Perfect Storm.” The movie is based on a 1991 real life drama about a sword fishing boat the Andrea Gail. To make a long story short the plot is about the crews attempt to leave their usual fishing grounds looking to improve their luck. Unfortunately multiple circumstances align causing the demise of the captain, crew and vessel.
It’s become the perfect storm now for the metrology industry. The United States has truly entered the global market for manufacturing. A couple of decades ago, there were an abundance of Metrologists who made their living and devoted their lives to understanding and performing measurement. Now, not unlike the tool and die industry, much of that expertise and dedication has retired or been forced out of companies which no longer see metrology as a priority for their organizations. If that scenario isn’t bleak enough, just try and find a school anymore that teaches the science of metrology. There are only a few universities in the United States that offer a program. The engineering schools only teach aspects of metrology to engineering students. Even the vocational schools who use to teach people how to work in our industry are gone. Like a Wall Street Journal article mentioned earlier this year – the skilled trades emphasis at colleges has been replaced by students who get liberal arts degrees and upon graduation are fighting for jobs as baristas. This is a national problem. Continue Reading
Justin Frazzini walks you through the process of how to effectively, efficiently and expeditiously pack your gage blocks to avoid damage in shipping as the latest in our A.A. Jansson video series. You can view the video here.
In a recent article from Today’s Energy Solutions, an article discusses Machine tool metrology systems that yield critical data for manufacturing trace-ability of critical oil/gas components.
Preventative Maintenance is a term often talked about but rarely performed. Approximately 25 years ago A.A. Jansson decided to get into the machine tool calibration industry. We researched the best calibration equipment on the market and made the necessary purchases and invested in the training required to help manufacturers make sure their machine tools were operating as required and as expected.

I feel compelled to get excited about World Metrology Day, which celebrates the signing of the Metre Convention by 17 nations. The event took place on May 20, 1875, but the county I live in never really accepted this form of measurement. The metre for the U.S. became, “Meh.” As far as I know the U.S. is the only country in the world that does not use the metric system as its predominant system of measurement. Ask any elementary or middle school student what a metre is and you will get a blank stare. Of course these are the same students who can’t read a clock with hands.
In 1968, the US Congress authorized a three-year study of systems of measurement in the US. The final report of the study was called, “A Metric America: A Decision Whose Time Has Come.” The majority of the study participants believed that conversion to the metric system was in the best interest of the Nation, particularly in the View of the importance of foreign trade and the increasing influence of technology in American Life. With the study complete, the U.S. crafted a planned transition to the Metric system and Congress passed the Metric Conversion Act of 1975. We all remember how well that went. I can still recall seeing the outfield walls of baseball fields showing metric distances. I can also recall the human cry in this country to eliminate this form of measurement as soon as possible. I think “new math” was more popular.
I also remember my father being extremely excited over Congress’s original decision. In fact, it wasn’t long before he ran to the Secretary of State Office and registered his first personal license plate. It read, “Metric.” I still have the license plate in my office waiting for the day that America embraces the Metre.

In a recent article in Quality Magazine, the author looked at ways that automation and robots are leading the charge for a “new landscape” in the metrology world.
At A.A. Janson, metrology is our business. For 5 decades we have watched coordinate measuring machine manufactures improve the accuracy of their product. In some case people might say it was a race to see who can manufacture the most accurate, fast and durable machine on the planet. They have not let us down. It is no surprise that robot manufacturers would try to achieve the same results.
A.A. Jansson President Eric Lundquist shares the second part of a two-part look at the specifics of Gage Block measurements. When we report an uncertainty of 3µin on a 1 inch gage block, what does that actually mean? You can view the video here.
One of the most frequent questions that we are asked at A.A. Jansson is, “How do I choose a plug gauge for my measurement application?” We have put this document together to help everyone understand the concept of fixed limit gauging.
