Two of the essential characteristics of any successful machine shop are speed and accuracy, but depending on the application, they can be relative terms.

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?

Celebrating its 80th year, Kennametal, the Latrobe, (PA), tooling manufacturer, says it has solved the age-long problem of tool stability when drilling in deep cavities, alongside tall shoulders, and past bulky fixtures. Reaching deep inside a workpiece to drill holes can be challenging.

Live Tooling, as the name implies, is specifically driven by the CNC control and the turret of various spindle and powered sub-spindle configurations on CNC lathes to perform various operations while the workpiece remains in orientation to the main spindle.

At the Nirvana Machine Shop on planet Perfection, every workpiece is clamped to a custom-built fixture mounted on a dedicated machine tool. Each workpiece is dimensionally identical to the one before and the one after. All the fixtures are totally automatic—instantly positioning, clamping, machining, inspecting, and releasing the part with the ultimate precision.

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.

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.

There is no real problem with threading a pipe. Most DIY types can do it in their workshop with hand tools, but when the pipe is 40′ long and ordered by the ton, you are in oil country. Pumping crude oil out of the ground requires drill pipe, casing, tool joints, tees, crosses, flanges, and couplings. All those items need to be machined. And that takes specialized workholding.

If you’re looking for new solutions to tooling and workholding challenges, IMTS was a great place to start. The bi-annual trade show, held this past September in Chicago, allowed shops to browse for the “latest and greatest” technologies.

With the number of offline and in-process toolsetting options on the rise, developing a way to efficiently utilize this technology can be confusing. Which presetter should we buy? What about the software that’s so often part of these systems—do we really need it?
