	Tube Hydroforming Design Flexibility—Part I By: Gary Morphy, Contributing Writer Publish date: May 16, 2002 Tech cell: Hydroforming
	The basic elements of tubular hydroforming By: Mustafa Ahmetoglu, Contributing Writer Many factors come into play when attempting to execute a production hydroforming operation, among them material selection, friction and lubricants, tube bending and preforming, and equipment. Many companies in the automotive sector are experiencing great success with the process, which can reduce weight, overall costs, and the number of parts per vehicle.

	Dealing with internal pressure in free hydraulic bulging: Predicting results with FEA By: Atsushi Shirayori, Contributing Writer For hydraulic tube bulging, direct pressure control is the most commonly used process. Pressure control allows engineers to determine the correct capacity hydraulic system and, more importantly, prevent tube rupture. However, inflow control, or control of the volume of fluid inside the tube, theoretically could be another viable hydroforming process. Finite element analysis has shown that inflow control could allow engineers to more accurately predict deformation behavior and therefore enhance the hydroforming process.

	Troubleshooting your stamping operation By: Herb Kamphausen, Contributing Writer A common thread runs through all effective troubleshooting approaches: the skill of observation. Learn to use it to your advantage. Publish date: April 24, 2001 Tech cell: Press Technology
	Pairing the right hydraulic press with your application: Getting the best return on investment with the right return By: Jay Douglas Hartzell Choosing the right hydraulic press for your application is crucial. Identifying the right press capability up front can eliminate additional costs and startup delays. Four primary hydraulic press return capabilities are return on position, return on pressure, return on pressure with dwell capability, or combinations of the three. Shown is a press with return on pressure capabilities. Publish date: October 11, 2005 Tech cell: Press Technology
	The pressure is on: Prolonging die life with the help of sensor film By: Mirco Graenert and Shawn Eeles The traditional method of measuring pressure distribution in stamping operations—the die spotting blue technique—reveals the pressure points without actual pressure readings, making it difficult to balance in relation to other die components. A thin, flexible, Mylar-based sensor film that instantly captures and permanently records pressure distribution and magnitude between any two mating or contacting surfaces has emerged as an alternative to traditional pressure testing.

	Setup or cover-up?: Too much bending pressure can � but shouldn�t � compensate for poor tooling setup By: William Q. Tingley III Setting up the tooling for a tube or pipe bending machine isn't as simple as it seems. Many variables are involved, making this a difficult task. A further complication is the tendency for many operators to adjust various pressure settings to compensate for poor tooling setup. The bend might turn out okay, but at a cost—a loss of process control and shortened tool life. Using a simple four-step setup process is the key to good bending, process control, and optimal tool life. This setup procedure also facilitates troubleshooting.
