Keeping Old Planes in the Air with Laser Scanning

Your father’s Oldsmobile may be long gone but his B-52 is still pulling missions, and they haven’t built the “BUFF” (Big Ugly Fat Fellow) since 1962. The last KC-135 tanker was built in 1965. Besides aging warbirds (the average plane in the US Air Force is over 28 years old) there are hundreds of ancient civilian airliners carrying friendlier payloads everyday. The key to doing this safely is of course excellent maintenance and periodic upgrades. Laser scanning plays an essential role.

2016 Was a Good Year for Lasers; 2017 Looks Even Better

Strong 2016 earnings among top industrial laser providers, continued brisk adoption of fiber lasers, cheaper ultrafast lasers, and a host of novel applications and notable corporate acquisitions signal a big year ahead for photonics-based manufacturing.

Advances in Titanium Machining—Do More on Less Floor

The demand for titanium components by the aerospace industry began as a whisper about 15 years ago and steadily grew to a sustained, raucous shout over the last five and likely won’t quiet for several more.

Maybe it’s Time to Try Some ‘Swiss Cheese’

These days the most important theme in superabrasive grinding wheel development isn’t the abrasive, it’s the bond. The diamond or CBN grains do the cutting, but the bond plays a decisive role in exposing the grains to the workpiece and enabling coolant to remove heat.

Picking the Right Toolholder for the Toughest Jobs

When sizing up an application for a milling toolholder, it is necessary to consider the materials being machined, how aggressively metal is going to be removed, and any machining conditions that are likely to present a challenge to tooling security. By now, the pros and cons of hydraulic, mechanical, and heat-assisted shrink-fit systems are well known and results well documented.

Tooling to Match Composite Production

It’s getting harder to imagine any market that isn’t benefiting from the latest developments in parts manufactured from advanced composites. “Advanced composites will arguably dominate consumer and production products, especially in the near future,” says Bert Erdel, industry consultant and executive technology advisor, Morris Group Inc. (Windsor, CT), “as they have begun to gain wide acceptance in solving energy-related issues.”

Solutions for Difficult Machining

The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.

What’s the Connection?

A lot of attention is paid to the “business end” of CNC toolholders–the part that actually holds the tool.
