	Mill coolant system design: Lubrication is more than meets the eye By: James Dyla, Contributing Writer What kind of coolant system you construct for your tube mill or roll forming operation is just as important as what type of coolant you use. Publish date: May 15, 2001 Tech cell: Roll Forming
	Meeting the Standard: Five must-have accessories for your next roll former By: Jeff Carson Using old roll forming technology is one thing, but it's another to use or buy equipment that does not have essential features that now are considered standard. Learn which five features must be included in roll forming equipment and why they simplify manufacturing. Publish date: January 9, 2007 Tech cell: Roll Forming
	Protecting surface-sensitive materials in coil processing: Array By: Array Array Publish date: Array Tech cell: Coil Processing
	Survival of the fastest: Modern cut-to-length line performance By: Ken Shoop, Contributing Writer Publish date: September 14, 2004 Tech cell: Coil Processing
	Protecting surface-sensitive materials in coil processing - Three potential danger areas By: Jim Russell, Contributing Writer As manufacturers worldwide strive to reduce costs and streamline their production processes, the market for surface-sensitive materials continues to expand. Surface-sensitive materials include all prepainted steel products and nonferrous decorative materials, such as copper, brass, and stainless steel.

	Hydraulic forming takes a front seat: How an automotive supplier improved quality characteristics on seat adjuster channels By: Tom Paisley, Contributing Writer For about 50 years roll forming was the process of choice for making seat track channels at Dura Automotive Seat Systems, Stockton, Ill. While the process was high-speed, low-maintenance, and flexible, it also caused channel end flare, twist, and bow. Publish date: April 24, 2003 Tech cell: Press Technology
	The basics of roll form tooling design: Understanding tube forming's not-so-distant cousin By: Chuck Summerhill, Contributing Writer You can successfully roll-form a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind; therefore, theory can go only so far.

	Using finite element analysis to roll-form tubes By: Karan Shah, Yingyot Aue-u-lan, and Taylan Altan, Contributing Writers Roll forming is a common method for producing steel tubes. It is a continuous process in which a strip is guided through several sets of rolls that form the strip into the desired shape. After the final shape is achieved, tube edges are welded together to form a closed section. After the welding operation, the tube is sized through another set of rolls to obtain the required diameter. Publish date: October 9, 2003 Tech cell: Tube and Pipe Fabrication
	Exploring the welded tube making process: The basics for fabricators By: Henry Niedzwecki, Contributing Writer This article is aimed not at tube producers, but at fabricators of tubing, to provide an overview of the process. Publish date: May 30, 2001 Tech cell: Tube and Pipe Production
	Solving Problems on the Tube Mill By: Robert Sladky, Contributing Writer Tube mill operators face a variety of challenges everyday in their efforts to produce high-quality tubing in a cost effective and productive way. Publish date: August 16, 2001 Tech cell: Tube and Pipe Production
	Using existing tooling for new product applications: Evaluating the tooling's capabilities and limitations By: David Jenkins Jr., Contributing Writer The article outlines factors for consideration when changing material type, grade, coatings, efficient speed requirements, specialty shapes, etc. Special consideration is given to the difference in speed between the minor relief angle and the root diameter.

	Minimizing wall thickness variation in seamless tubing By: Wynn H. Kearns, Contributing Writer All mechanical steel tubing has some amount of wall thickness variation. Wall variation in welded tubing results from the strip manufacturing and tube welding processes. Seamless tube, which is created from a hot billet of solid steel, has wall variation that results from tooling wear, bearing and shaft variation, and normal hot-process variation. The wall thickness in seamless tubing varies in the cross section and along the tube's length. Publish date: August 28, 2003 Tech cell: Tube and Pipe Production
