White-light metrology is a noncontact method that uses a familiar, safe light source—simple white light. Simplicity and accuracy may make white light the system of choice in many applications.

Not all threaded connections serve similar purposes.The load-carrying needs of an aerospace engine support bolt in a tension assembly greatly exceed those of a simple screw that fastens a cover plate to an electrical wall socket. International thread-acceptance documents and standards recognize this basic engineering fact, and incorporate different thread-inspection requirements into their verification standards.

Technology is changing ever more rapidly. Sometimes this means topics learned in engineering or technical school become obsolete. Whole new fields emerge within a few years, so that even those with freshly minted educations suddenly find themselves faced with new challenges.

Basic trends in modern manufacturing are driving growth in 3D optical metrology. “One is the highly complex and high-tech material that manufacturers are using today. For example, in the aerospace turbine blade market, they simply cannot touch the part like they used to—the surface finish of the material is too readily affected by any kind of contact metrology."

In today’s rapidly changing manufacturing landscape, Clemson University (Clemson, SC) takes a fresh approach to manufacturing education for the nation’s future automotive engineers.

At the Digital Manufacturing and Design Innovation Institute (DMDII) in Chicago on March 27, Siemens demonstrated its approach to the “Fourth Industrial Revolution.” At its annual U.S. Innovation Day, Siemens demonstrated real-world applications of digital solutions that it says will reduce costs, increase speed, develop new business models, and improve quality of life.

Beware predictions of the demise of any technology. If the early 1920s saw the dawn of the optical comparator, there has been much speculation about its sunset. That was especially true when vision systems started hitting their stride a few years ago. Many could see optical comparators were superfluous with the use of vision systems. Many thought the sunset of optical comparators was imminent. Many were wrong. Why?

ASF Metrology (Varallo, Italy) will acquire the coordinate measuring machines (CMM) business from Nikon Metrology which intends to  focus on non-contract metrology. 

There are many times when a machinist, while cutting a few parts or getting ready for an initial run, needs to check a few parts or a few critical features.

Manufacturers need to embrace artificial intelligence to make their operations more efficient, a consultant said.
