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.

Science Nonfiction

August 8, 2002

By:

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.

Turning up the power

July 12, 2001

By:

The most common power levels ranged between 1,500 and 2,000 watts. However, a statistical survey conducted by the AMT Laser System Product Group indicates a steady increase during the last 12 months of installations for high-power 3,000- to 4,000-watt laser systems and a decline in sales of lasers with power levels less than 2,000 watts.

Predicting the outcomes of laser thermal forming

April 24, 2001

By:

Applying a laser or any other high-density heat source to the surface of a metal sheet for a short time will distort the metal. If this distortion could be predicted, the laser could be directed so that the sheet metal would form the desired shape. This idea opens up many possibilities, including...
