There are many reasons why firms need to model the exterior contour of existing aircraft outer mold lines (OML). Most aircraft flying today were not designed in a modern 3-D CAD system. Even with a current 3-D digital design, the actual as-built contour deviates from the intended shape, at least…

n 2006, the Massachusetts Institute of Technology (MIT) kicked off a project called the Vehicle Design Summit (VDS), which today has grown into a large international consortium of teams from universities and innovative companies seeking, among other pressing global needs dealing with energy and…
Hiram Powers (1805–1873) is considered one the America’s great neoclassical sculptors. His works were popular in his time and remain so today. The Smithsonian American Art Museum (SAAM) has one of the most comprehensive collections of Powers’ work featuring major sculptures in marble, as well as…

Not too long ago, when you wanted a product to be leak-proof, you simply put it under water, made sure it didn’t bubble, and thereby concluded there were no leaks. Such “bubble testing” takes time and depends on the operator’s ability, making it totally inappropriate for the modern production…
The client is a small independent company that just made a $600 million bet on a new deepwater floating platform to develop a Gulf of Mexico field, which bigger companies considered too small to develop themselves. Get it right and the client doubles production next year. Get it wrong… well, do…

few years ago a Missouri-based casting company, O’Fallon Casting, realized that its touch probe-based inspection system was stretched to the limit for most of its rapid prototyping work. O’Fallon Casting took a new approach by installing a cross scanner from Nikon Metrology plus PolyWorks…
Under an indefinite delivery/indefinite quantity (IDIQ) contract with the U.S. General Services Administration’s (GSA) Great Lakes Region, Ghafari Associates LLC, a full-service architecture, engineering and consulting firm, was selected to design the restoration of the Chicago Federal Center (CFC…

The collapse of the global economy has put a lot of manufacturing companies out of business. Even at this late stage of the recession, there are still auctions of recently closed plants conducted every day. There are many more manufacturers struggling to reduce their operating costs and improve…
With today’s limited internal resources, it’s tough to transform machine maintenance from reactionary to preventive, and ultimately proactive, despite the obvious upsides in higher overall equipment efficiency (OEE), better process control, and lower total cost. Outsourcing this requirement to a…

A company based in the U.S. Southwest makes innovative optics for racing cars and other extreme vehicles. Recently the owners, who grew up in Southern California’s skateboard culture, came up with a new product idea for a kick scooter, mainly for kids, based on the design of a skateboard. The…
Direct Dimensions Inc.
In 2009, Direct Dimensions Inc. was approached by Texas A&M University’s Flight Research Laboratory (FRL) with a challenging yet typical 3-D problem. The FRL, while primarily an active teaching facility, also offers both flight and wind tunnel test services. This particular project was for a…
Consider the most fundamental of measurements: the measurement of physical distances, as when we use feet and yards, or meters. Once upon a time, a foot must have been thought of as the size of, well, a human foot, without worrying whose foot exactly. These days, we are no longer satisfied with…
Environmental Quality Corner with Ken Appel
No quality control system is perfect. Just think “Toyota” in the context of today’s headlines and that should be abundantly clear.
Taking Toyota’s predicament to heart—for any quality manager in any industry—means thinking through where the inherent weaknesses are in production processes and…
The powder metallurgy (PM) process offers manufacturers the ability to produce high volumes of complex parts in a cost effective manner. Many powder metallurgy components go through heat-treat processes producing parts with increased strength or wear resistance. To ensure the quality of the heat…

Today’s challenges in the turbine industry to meet the ever growing requirement to manufacture parts faster, on schedule, and at reduced costs, have made it apparent to industry experts that traditional inspection methods are too slow and inadequate to achieve the required results. With the…

A mechanical engineering firm was contracted to install new cooling equipment in a municipal ice rink’s mechanical room. The challenge was to design the equipment installation without tearing out the old equipment first, and to install some elements and piping that housed the refrigerant around…
Coordinate Measuring Machines (CMMs) are used in practically every industry that requires precise dimensional inspection of manufactured parts. In today’s competitive environment, manufacturers demand CMMs that are accurate, reliable, fast, economical, and provide maximum flexibility with respect…
Located near Montreal, Canada, the Nova Bus manufacturing team was routinely building many hundreds of complete bus frames per year. Production grew as new models were introduced. The addition of a new diesel electric hybrid design necessitated a re-examination of the quality inspection…

Although he’s not one for clichés, Rus Emerick, process improvement specialist at Schneider-Electric, endorses this one: “The whole is greater than the sum of its parts.”
This concept, which dates back to Aristotle, is at the core of an approach called functional analysis that has…

As “Old Man Winter” continues to toss his wrath at many of us, it is quite easy to turn our thoughts toward warmer, sunnier places. One of those locations we are all starting to think about is Reno, Nevada, the location for the 2010 Coordinate Metrology Systems Conference (CMSC) hosted by the…

With a silicone rubber “stick on” sheet containing dozens of miniature, powerful lenses, engineers at Harvard are one step closer to putting the capacity of a large laboratory into a microsized package.
The marriage of high-performance optics with microfluidics could prove the perfect match for…
A spring-loaded guided core AC-LVDT is an air-extended, spring retracted LVDT offering consistent measurement for dimensional gauging, factory automation, and similar position measurement applications.
