Laser beam sources with higher output powers and improved beam qualities have expanded the range of laser applications. Most system's lasers have power higher than 2 kW. Higher power does not always increase the speed, however. Increasing the power during thermal cutting value may cause increased heat-affected zones on the material and place higher demands on the motion system, thus limiting the cutting speed. A new patented cutting machine, the diffusion-cooled CO2 slab laser, may offer improved beam quality and smaller focus diameters under conditions comparable to conventional fast-axial-flow CO2 laser with 4-kW output power.

Paramount Fitness Corp., a manufacturer of strength training equipment, used to purchase small quantities of laser-cut parts from outside vendors. Its desire for a laser could not be justified because the quantities of parts were so low. Engineers at TRUMPF worked with Paramount to create special fixtures so that a TC L 2530 sheet metal laser could handle tubular parts. The company soon found the new laser running 10 hours per day, six days a week. In keeping with the company's strategy to reduce direct labor, it soon justified a TUBEMATIC to handle its tubular parts.

Today's laser sources have the power and beam quality needed to cut and join metal in an expeditious and repetitious manner. The market demands that type of flexible production, so those characteristics are basic requirements in modern laser devices. The market demands also have promoted the idea of multifunctional processing. That has led to the development of a combination head capable of laser cutting and welding 3-D metal work pieces.

Kvaerner Power Inc.'s Fairmont, W.V., metal fabricating operation needed new market opportunities and someone to take over plasma cutting chores after its business partner went out of business. They found a Pennsylvania job shop to help with metal cutting and eventually learned that a 3-D laser could help them bring their outsourced jobs back in-house and that the laser could lead to new business.

Metalen Verhoestraete, a metal service center in Roeselare, Belgium, needed a laser, but not just any laser would do. Because many of the company's clients had 3- and 4-meter lasers, Metalen sought a laser that had a much longer bed so it would not compete with its customers.

Contract manufacturer CGI Automated Manufacturing Inc., Cicero, Ill., fabricates parts as an outsource resource for vertical manufacturers. The company started out as a stamping operation, then added other fabrication technologies, including welding, press brake forming, drilling, punching, rolling, shearing, and cutting.

Bourgault Industries specializes in seeding and tillage equipment, and other agricultural products including sprayers, grain carts, and heavy harrows. The company performs all fabrication involved in manufacturing the equipment from sheet or plate to finished product. It examined its operating costs and found that setup times in several parts factored significantly in the overall cost of the part.

As we all know, the laser industry has seen easier times. Economic and market pressures have changed the competitive landscape for laser cutting equipment, and the changes are likely to continue. Both lasermakers and laser users need to adapt to the changes in the laser market, and the companies that recognize and adapt first are likely to be those that succeed.

Today's job shop market is characterized by unrelenting competitive pressure for laser processing services. Job shops are expanding into niche services such as multiaxis laser processing and thick plate applications to differentiate themselves from their competitors. Others are performing additional services such as forming, welding, painting, and assembly to add value.
