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.

At military installations across the country, repair personnel struggle to stretch the life spans of vital pieces of equipment. Sometimes welding can extend the life of damaged components in aircraft, tanks, and other military vehicles. But in some cases, high–temperature welding processes do more harm than good, warping and weakening delicate metal components. Previously such components would be classified as irreparable and replaced with pricey new parts.

CO2 lasers were used predominantly for cutting flat sheet metal for many years. Advancements in laser beam quality, power, manipulation, and material handling features have propelled the CO2 laser into new areas of fabrication. Multidimensional cutting, increased cutting capacity, and the ability to cut a wider range of material types make the CO2 laser a popular thermal cutting process in today's metal fabrication industry.

Editor's Note: This article is Part II of a four-part series covering flatness and stability in cut-to-length, slitting, and tension leveling operations. This article discusses flattening solutions and the anatomy of a bend. Part I, which appeared in the October issue of The FABRICATOR®, discussed how flat-rolled metal gets unflat; Part III in the December issue will address how coil processors can make metal flat so it stays that way; and Part IV in the January 2003 issue will discuss new applications and options in leveling equipment.

Metal cutting lasers continue to evolve at an amazing rate, largely based on the demands of OEMs and job shops, while profit margins shrink because of increased competition and lower pay rates. To help fabricators meet the demands placed on them, laser manufacturers are creating new laser features that help fabricators differentiate themselves, speed up productivity, and get more out of their laser machines.
