Laser Cutting Articles

The laser cutting technology area has information on 2-D and 3-D cutting machines, optics, resonators, cutting gases, and automated material handling systems. In addition to conventional CO2 systems, it has information on solid-state fiber and disk lasers.

Engineering firm enters the 3-D world of laser cutting

October 20, 2011 | By Dan Davis

A defense contract drove Systems Engineering & Manufacturing, Forest, Va., to seek out a flexible fabricating tool that could handle bent tube and structural shapes, and the fabricator found its answer in a laser cutting machine that could accommodate 2-D and 3-D parts.

Nesting software keeps the “lights-out” on

September 9, 2011 | By Cornel TerreBlanche, John Leuzinger

"Lights-out" laser cutting-defined as a machine laser-cutting parts without the need of operator intervention, typically during an unmanned evening shift-can only occur when the cutting head can move around the sheet unencumbered. Advanced nesting software can ensure that "lights-out" remains on.

Arin Inc. has evolved from a steel rule blanking house to a modern metal fabricator capable of producing precision, laser cut blanks. Bu workers can see history every day--a tool room for steel rule die remains, as do the mechanical presses. A tour of Arin's shop is a walk through time, a gallery showing what metal fabrication talent has produced over the decades.

Seeing the (green) light

August 1, 2011 | By David J. Stone

More lasers or punch presses may enable a shop to cut more parts, but those parts still must be loaded, unloaded, and transported to downstream operations. In these cases, automation can help increase green-light-on time and help a shop produce more parts in less time.

Gas equipment for CO2 laser cutting: A primer

July 8, 2011 | By John Karpus

Precise assist gas delivery is essential in CO2 laser cutting. The resonator is a key component, especially if gas delivery will be uninterrupted for unattended machine operation. Assist gas volume and pressure also must be appropriate for the application to ensure the best results.

One laser head, one plasma torch, one cutting table

July 8, 2011 | By Douglas Shuda

The fiber laser and plasma systems share similar delivery systems. Neither require any kind of optical alignment between the power source and cutting head. The two thermal cutting processes share many similarities, from an integration standpoint, which is why the two now can be integrated onto a single cutting table.

Laser cutting thick stainless steel—fast

January 17, 2011 | By Tim Heston

Fabricator uses a 7-kW CO2 laser cutting system to cut thousands of thick, stainless steel components for a critical component of nuclear plant safety. Today, the shop hopes to leverage its technology to gain work in other sectors.

A case of the gas

January 10, 2011 | By Dan Davis

If a job shop supplies metal parts that are to be powder coated or welded, the customers likely require that those fabricated parts have no oxidized edges. That requirement forces the job shop to cut with nitrogen, which doesn't leave an oxidized edge like oxygen. Unfortunately, cutting with nitrogen is expensive because much more nitrogen is consumed when compared to oxygen to perform similar cuts. This situation led a metal fabricator to investigate nitrogen generation systems. This is his tale.

Analyzing the potential of the solid-state laser

July 1, 2010 | By Tim Heston

Fiber lasers have enormous potential in metal fabrication. They aren't a panacea, but for certain applications, they may be extremely attractive. They're solid-state, require less maintenance, and often can cut twice as fast as their CO2 counterparts.

Blended laser-assist gases: Recipe for successful materials processing

February 23, 2010 | By David Bell

Now processing a greater variety of materials with their lasers, fabricators are exploring new assist gas blends of up to four gases. What's the best way to blend and deliver these gases? For some, on-site blending systems can help optimize cost savings and improve quality.

The importance of focal positions in laser cutting

January 8, 2010 | By Frank J. Arteaga

If the proper laser beam focal position and projection shapes are maintained within the material to be processed, the balance of the requirements necessary to producing a consistent, high-quality laser-cut are kept to a minimum. That's why it's important for laser cutting equipment operators to know the rules of laser beam focusing.
