	Do you see the light? By: Dan Davis, Editor-in-Chief In this article, The FABRICATOR® attempts to shine the light on opportunities for improvement in both the front office and on the shop floor. In this case, the light is on the lights—as well as the heating and ventilating system and other energy-sapping devices. Publish date: February 26, 2004 Tech cell: Shop Strategies
	High-Speed Feeding Techniques - Reviewing the Facotrs that Affect Process Speeds By: Al Lochtefeld, Contributing Writer Gripper or roll-type feeds operate on the principle of feeding force, which is a product of the coefficient of friction between the grippers or feed rolls and the material being fed. Reviewing each force as a factor of the feeding equipment or feeding conditions helps in evaluating the feeding process. Publish date: February 19, 2002 Tech cell: Press Feeding
	Appliancemaker reduces downtime with stamping press feed system: Inconsistent feeds caused die jams, inconsistent parts By: Kate Bachman, STAMPING Journal® Editor The Whirlpool Co. builds refrigerators at its facility in Fort Smith, Ark. The company stamps the appliance parts—large and small, galvanized, cold-rolled, and aluminum—on approximately 35 presses. The majority of its stamping presses are straight-side machines, although some are open-back inclinable (OBI), and a few are hydraulic. Publish date: January 13, 2004 Tech cell: Press Feeding
	Hydraulic workholding from scratch: How to select and set up components By: Thomas Eggert, Contributing Writer Hydraulic clamps are used in place of manual or toggle clamps to hold the workpiece or tool in place during stamping. This article examines the four steps that comprise the selection and installation of a hydraulic workholding system: cylinder selection, cylinder force and stroke, power source selection, and system connection.

	Do you use checking jigs and fixtures?: An ounce of prevention is worth a pound of cure By: Dave Petrack, Contributing Writer How do you check tube fabrications to ensure they meet quality standards? Do you ship parts without checking them and hope that the next time the phone rings it isn't a prelude to a tirade from a disgruntled customer? Or do you check finished parts only to realize that your scrap rate is too high and wish you had checked them at earlier stages of the manufacturing process?

	Structural tube on campus: Aluminum bridge spans science departments Central Washington University in Ellensburg, Wash., is known for its strong science programs. "Flying Bridge," a structure designed by artist and sculptor Ed Carpenter, physically and metaphorically spans the biology and chemistry departments in the university's new Dean Science Building. Carpenter, who designed the bridge with engineering consultation from Peterson Structural Engineers Inc., teamed up with Albina Pipe Bending Co. Inc. to tackle the project's material bending and fabrication requirements. Publish date: January 13, 2004 Tech cell: Tube and Pipe Fabrication
	Tooling, the key for mill production By: Robert Stroud, Contributing Writer This article discusses three main criteria that govern tube mill tooling—design, materials used in their construction, and alignment of tooling on the mill. Discusses advancements in design due to CAD technology; experimental use of ceramic and plastic materials for making tooling; and the use of subplates and interchangeable components to ease tube mill alignment.

	Choosing the right oxyfuel gas and supply system By: David Bell, Contributing Writer Mixing oxygen with fuel gases for brazing, cutting, heating, and welding metal has been around since the early 1900s. Oxyfuel processes have remained in use over the years despite the introduction of other metal fabrication processes, such as arc welding, plasma cutting, and laser materials processing. Finding the most economical method for supplying oxyfuel gases requires a basic understanding of the process. Publish date: November 6, 2003 Tech cell: Arc Welding
	Welding exhaust system components: Laser technology may aid this traditionally high-volume application By: Frank Brennan, Contributing Writer In the field of automobile exhaust systems, such components as manifolds, pipes, catalytic converters, and mufflers are joined either by the car manufacturer or by a subcontractor to form a subassembly ready for attachment.
