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.

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.

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.

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.

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.

Hi-Tech Industries of New York invests heavily in automation, including a new laser cutting center and robotic press brake--large investments unusual for a typical job shop. But this is no typical job shop.

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.

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.

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.

Beverlin Manufacturing Inc., a tube producer and component fabricator, struggled with various cutting processes. Its produces and fabricates perforated tube which, because of the perforations, complicates the cutting process. After using two sawing methods, it changed to laser cutting.
