Erik Larson’s latest book begins with this quote. If you’ve ever read a book about a serial killer and the Chicago World’s Fair of 1893, the last crossing of the Lusitania, an American family in Hitler’s Berlin, the inventor of wireless and Britain’s second most famous murderer, or the 1900 Galveston Hurricane, you may be familiar with Erik Larson.
I was chatting with a colleague recently, a well-known supplier of precision measuring instruments. I noted, sarcastically, that his company was promoting a half-day training seminar on calibration and best of all—it was free!
Thickness measurement is the gauging of coatings or films on surfaces—such as paint on metal parts. Manufacturers are increasingly using thinner and higher-performance coatings these days, with tighter applied thickness tolerances and an increasing need for more accurate and precise tools.
East Coast Metrology LLC. (ECM – Global Measurement Solutions) announced the opening of a new training, service, calibration and retrofit facility in Wixom, MI.
Typical answers include: cheaper, faster, most accurate, none of which would pass a technical smell test. On reflection, many might say they want calibration to tell them if the item to be calibrated is any good or not while not defining what ‘good’ means from a technical point of view.
Specifications for surface texture frequently focus on surface “roughness”—the finer structures in the texture—often to the exclusion of the “waviness”—the larger structure of the texture. Unfortunately, problems related to sealing, vibration, noise, wear, etc., are regularly caused by issues hidden in the waviness domain, which cannot be captured by common roughness specifications.
