Typically, compressed air or nitrogen circulates in the plenum to ensure that water, dirt, dust, smoke, haze, and solid particulate matter are absent so that the mirrors in a laser resonator do not become cloudy. In recent years, membrane air dryer systems that provide drying and removal of particulate matter have been developed for flushing the beam path.

Bobcat determined that the nesting software on its laser cutting systems didn't maximize the capabilities of the machines. After the company decided to purchase new nesting software, programmers outlined what capabilities they wanted. The company purchased ProNest® from MTC Software, Lockport, N.Y. The company has gained positive returns from the new software, which enables more control of process specifications.

H.W. Metals offers punching, shearing, arc welding, machining, oxyfuel cutting, and standard and high-definition plasma cutting. The company found that there was more and more work it couldn't do for its customers because some jobs required laser-cut parts. The company decided to purchase a laser to expand capabilities in its current markets by offering an alternative to plasma cutting. In October, the company installed a Prima Maximo laser cutting system, which will allow the company to provide more capabilities to existing customers.

Hawkeye Industries Inc., Tupelo, Miss., was getting more and more orders for parts that required both punching and laser cutting. To meet the growing demand, the company purchased a combination punch/laser machine. Some shops are more suited than others to this technology—combination machines can increase profits for some companies, and costs for others. Shop owners should keep five key things in mind when evaluating and purchasing a combination punch/laser machine.

This article was developed from the Comparative Cutting Panel conducted at the Fabricators & Manufacturers Association's Metal Matters conference in Orlando, Fla., March 2008. The participants included Rick Neff (Cincinnati Incorporated), Chris Maier (Flow International), Jeff Hahn (MC Machinery Systems Inc./Mitsubishi Laser), Ron Schneider (Messer MG Systems & Welding Inc.), and Al Julian (W.A. Whitney Co., a division of MegaFab).

How can laser technology make metal fabrication more efficient? The efficiency comes not only from advances within the laser itself, but also in new ways to integrate those lasers for optimal part flow on the shop floor. Several presenters at ALAW 2008 hammered this point home.

Lasers are capable of cutting thin-gauge metal and plate at incredible speeds and with outstanding results. But a laser also is capable of great damage to operators if the proper safety steps are not followed. To keep everyone safe and the laser cutting machine operating, a fabricating operation should have a safety program in place.

Several modes of nitrogen assist gas supply exist, but with choice comes the potential of saddling your business with overhead costs that make it difficult to compete. The best approach is to map out a growth strategy, using each option's performance and value, that coincides with monthly nitrogen usage.
