	Cutting through the obstacles: The challenges of sawing structural tube, pipe, and solids By: David Byrley and Dave Burkhart, Contributing Writers Of all the materials that can be cut on industrial band saw machines, structural steels—such as pipe and tubing, plate, angle and channel iron, and I beams—are all among the most common and challenging. Publish date: December 11, 2001 Tech cell: Sawing
	Take the old with the new - Selecting saw blades with new technologies in mind By: Dave Byrley, Contributing Writer New methods for cutting tube and pipe have been introduced to welding shops in the last few years—methods designed not only to cut metal, but also to cut costs. Publish date: May 29, 2003 Tech cell: Sawing
	Blast Cleaning Equipment: What you need to know before buying By: Mike Gignac, Contributing Writer If you are a fabricator of metal parts that need to be primed or painted, then you more than likely will have to prepare the part surface before finishing to produce the desired end result. Publish date: October 23, 2003 Tech cell: Finishing
	Choosing the right coated abrasive for plate finishing applications: A look at grain properties By: Mark Boudreau and Dave Jacoby, Contributing Writers Most plate fabricating companies need to select a coated abrasive to finish their parts. This selection process can be intimidating, as well as confusing, because so many types of coated abrasives are available. Publish date: January 29, 2004 Tech cell: Finishing
	Using hydroforming aluminum components versus steel stampings: The contender gains points, but the champion is still in the fight By: Daniel Hunter, Contributing Writer This article examines two transitions that are occurring in the automotive industry—the change from stamping to hydroforming, and the substitution of aluminum where steel was used previously. Publish date: November 15, 2001 Tech cell: Hydroforming
	Eliminating final trim shearing of hydroformed tube By: Donald Godfrey, Scott Huth, and Murray Mason, Contributing Writers The most common way to establish tube length after hydroforming is by cutting or shearing the tube to a specified dimension; however, cutting out this step can reduce scrap. A new method designed to eliminate this step combines forming the end of a tube to resemble its final form with using a hydroform die to correct end position variations off the bender. While this approach eliminates the final shear trim operation, it also presents new challenges. Publish date: October 9, 2003 Tech cell: Hydroforming
	Pairing a servo feed with a pull-through straightener: Applications for noncosmetic stamped parts By: Todd Wenzel, Contributing Writer This article explores the possibility that servo feeds can be used with pull-through straighteners as opposed to a conventional feed line that uses a powered straightener. Using the servo-PTS (pull-through straightener) can save money on equipment and material. The only limitation may be marking the material so noncosmetic applications are recommended.

	New Features in Coil-to-Coil Slitters: Adapting to the changing coil industry with technology By: Chuck Damore, Contributing Writer Years ago it was customary for coil processors to have dedicated slitting lines for specific materials and gauges. Today's larger, stronger, and thinner-gauge coils, however, require service centers to be able to process many materials and gauges on the same machine.

	Standardizing finger tooling: Modular systems provide alternative to dedicated transfer tooling By: Sharon Patton, Contributing Writer Modular, adjustable, articulated finger tooling for transfer presses may provide the flexibility you need to increase productivity and efficiency in your stamping operation. Publish date: September 4, 2001 Tech cell: Press Technology
	Designing high-strength steel stamped parts for formability By: Art Hedrick, Contributing Writer The use of high-strength steel to manufacture automobiles and other transportation vehicles has increased dramatically. The material's strength allows manufacturers to reduce vehicle weight substantially and increase fuel efficiency, without sacrificing performance.

	Controlling flow and obtaining stretch in deep draw operations By: Art Hedrick, Contributing Writer Addressing the difficulties in obtaining a wrinkle-free stamped part requires a good understanding of metal flow and how it is affected by draw beads Publish date: February 19, 2001 Tech cell: Tool and Die
	Rising expectations spark new approach to draw die development: Reconciling demands for increased quality at lower costs By: Greg Faucher, Contributing Writer A recently formulated approach to draw die development incorporates simultaneous engineering to identify and address potential problems before dies are built. Publish date: June 13, 2001 Tech cell: Tool and Die
	Controlling bend angles By: Art Hedrick, Contributing Writer Bend angles are among the most frustrating geometric features to control in metal stamping. This is due primarily to two factors – the inconsistency of the mechanical properties in the metal being bent and the die design. Publish date: October 9, 2003 Tech cell: Tool and Die
	Producing holes in tubing: Comparing the piercing and punching methods By: Todd Bryson, Contributing Writer Need to put a hole in a tube? This article provides an overview of tube punching and tube piercing, exploring the different variations of each method and comparing the two methods on cost, safety, and flexibility. Publish date: May 15, 2003 Tech cell: Tube and Pipe Fabrication
	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
	Skelp edge preparation for manufacturing ERW pipe By: Lew Warren, Contributing Writer Preparing the edge of a metal strip properly before it enters an electric resistance welding tube mill makes a huge difference in the quality of the final product. Make sure your prep methods match your quality requirements. Publish date: May 30, 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.
