Laser cutting has been a widely accepted fabricating technology for almost 20 years, yet with more new blood entering the industry, some fabricators lack a deep understanding of the cutting technology. This tip sheet aims to boost their laser cutting IQ.

Metal fabricators have been using CO2 lasers for decades and fiber lasers for years, but these technologies aren’t optimal for making the ultrafine features needed for medical devices such as catheters and stents. Femtosecond disk lasers recently have emerged as a viable technology for such applications.

Fabricating metal parts for price-sensitive customers means that Lynam Industries Inc., Fontana, Calif., has to make the right investments in technology at the right time. The investment has to contribute to the reduction in production costs. The metal fabricator's purchase of a fiber laser cutting machine in late 2013 is a recent example of this strategy.

Assist gas aids cutting and evacuates molten material from the kerf. It’s a key variable, one that may be the culprit for a bad cut edge. Just know that it’s not the only potential culprit.

Despite having low- and high-powered laser cutting machines and two waterjets, a fabrication shop recognized that it might have a need for more laser cutting capacity. To fill that gap, Advanced Laser & Waterjet Cutting installed a 1-kW CO2 laser cutting machine.

In 1973 full-time farmer Mike Van Mill tried his hand at building a grain wagon for a neighboring farmer, and he has been at it full-time since incorporating Brent Industries a few years later. Now the operations manager for Unverferth Mfg., Shell Rock, Iowa, Van Mill is part of a team that manufactures implements under the Brent brand name. The staff runs the facility like a savvy farmer runs a farm, always looking for a better way but proceeding cautiously. A sheet laser purchased in the early 2000s led to a tube laser purchased in 2014.

Edge quality in laser cutting has improved significantly over the decades, and many of those improvements come from four areas: better materials, nozzles, process control, and beam quality.

Solid-state lasers theoretically could cut through thin sheet at up to 1,000 meters per minute, though no machine in the world can drive a laser at that speed. But new approaches to laser cutting are bringing laser cutting speeds closer to the theoretical maximum.

Not all parts need the tight-tolernace edge that laser cutting provides; now a fabricator canhave the fine touch of laser cutting and the poweful force of plasma cutting for thicker materials in one machine.

Modern laser cutting technology can achieve speeds of more than 400 inches per minute, and that puts pressure on the automation used to load sheets and unload cut parts and skeletons. If the automated material handling system can’t keep up, the fabricator won’t be able to maximize uptime on the laser cutting machine.

To bring in more high-volume work, Deltec Inc., Batavia, Ohio, needed to expand its laser cutting capacity. New fiber laser cutting technology proved to be the right fit.

The high-brightness 1-micron cutting laser is redefining productivity in metal fabrication. The laser’s good absorption helps it cut faster with less power. It also means that keeping optics clean and dust-free is essential.
