When I graduated with an engineering degree some decades ago, I learned that the organizations I was going to work for had internal communication problems. This was especially true for those that designed and manufactured complex machinery such as engines, aircraft, or automobiles.

It’s easy to become dazed by the continuing stream of buzz words. For those of us in manufacturing, all this buzz creates a sense of impending change, but no clarity on what that change might be. Uncertainty means anxiety.

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?

In the last seven to eight years, solid-state lasers have come to dominate laser welding and cutting,” said Tom Bailey, product specialist for Trumpf Inc. (Farmington, CT). While Trumpf still produces CO2 lasers, for most applications solid-state lasers literally outshine them.

Lasers — well-established tools in the manufacture of medical devices—are continuing to break ground by producing smaller, more precise and more functional parts thanks to faster pulse speeds at lower cost, new applications and the marriage of laser processing to Swiss-style machining.

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.

Simulation in manufacturing is becoming much more pervasive. Advanced visualizations are used everywhere, from machining on shop-floor CNCs to offline CAD/CAM programming of NC equipment.

There’s growing evidence that some of the moldmaking business that fled the U.S. chasing cheaper sources offshore is returning. Moldmakers are not finding enough of a favorable cost differential to offset poor mold performance and the need for rework of faulty molds.

With much faster processing speeds and higher quality, you might think laser welding would quickly take over the field. But traditional welding hangs on. And depending on who you ask and what applications you consider, it may never go away.

Using lasers to cut metal, especially sheet metal or tubes, continues to show its value. The market is becoming dominated by the newer solid-state fiber laser over its CO2 gas rival. Fiber’s advantages in ease of operation, packaging and efficiency are clear.
