	Introduction to advanced high-strength steels: Array By: Array Array Publish date: Array Tech cell: Metals/Materials
	Improve HSS part quality before die tryout: Calculating springback compensation with simulation software By: Dr. Markus Thomma and Thomas Brenne The use of high-strength steels (HSS) and aluminum in automotive and other stamping manufacturing is creating forming challenges for tool and die engineers. Forming simulation software, formerly used to predict conventional failure causes, now also enables the stamping tool and die engineer to simulate secondary operations, including springback to avoid expensive and time-consuming die tryouts.

	Introduction to advanced high-strength steels - Part II: Processing considerations By: Daniel J. Schaeffler, Ph.D, Contributing Writer Understanding and compensating for the challenges associated with processing advanced high-strength steels (AHSS) can help you minimize springback, edge cracking, trimming, wrinkling, and die wear. Publish date: September 13, 2005 Tech cell: Metals/Materials
	Clearing the springback hurdle: Knowledge and planning are keys to success By: Eric Kam Springback is a fact of life for stampers, but knowing what causes it and how to deal with it -- through stabilization, compensation, and verification -- can help them overcome the problem. Publish date: September 11, 2007 Tech cell: Press Technology
	Know your bending basics—Part 1 By: Art Hedrick, Contributing Writer Knowing how metal bends and what factors come into play during bending -- especially wipe bending—can make a positive difference in your stamping operation. Publish date: May 15, 2001 Tech cell: Tool and Die
	Die designs for wide bends: Bending more than 90 degrees can be fun! By: Chester J. Punicki, Contributing Writer If you're a die designer, a standard precision progressive die can present countless challenges for you. Some of these dies have to produce thin slots, small holes, or tricky coins. Publish date: March 13, 2003 Tech cell: Tool and Die
	Die Basics 101: Part IX By: Art Hedrick, Contributing Writer This installment in the Die Basics 101 series picks up where Part VIII left off in describing the mechanical properties and behavioral characteristics of metals used in stamping operations. Among the topics discussed are strain, springback, stress, stretch distribution, n value, r value, and surface topography. Publish date: August 8, 2006 Tech cell: Tool and Die
	Measurement, assembly, and welding: Ultra Tool's quest for in-die perfection: Array By: Tim Heston Array Publish date: Array Tech cell: Tool and Die
	Measurement, assembly, and welding: Ultra Tool's quest for in-die perfection Part I: Part I: Errorproofing with in-die measurement Ultra Tool & Manufacturing launches a program to tackle sensor technology in an effort to errorproof the pressroom.

	Can I form a box that deep? By: Steve D. Benson, Contributing Writer There's no reason you can't form sharp, deep boxes with a press brake consistently. You just have to be familier with what your tooling can and can't do under certain circumstances. Publish date: July 11, 2002 Tech cell: Bending
	Fighting springback in profound radius bends: The effects of punch and V-die angle interaction By: Steve D. Benson, Contributing Writer When bending sheet metal, three terms apply to the radius of the bend: sharp, radius, and profound. A sharp bend has a radius less than 63 percent of the material thickness. A radius bend has a radius between 63 percent and 10 times the material thickness. A profound radius exceeds 10 times the material thickness and an entirely new set of rules apply. This article presents those rules. Publish date: September 17, 2001 Tech cell: Bending
	Oversized V dies: the effects on bottom bending By: Steve D. Benson, Contributing Writer Using oversized V dies in bottom bending can damage press brakes and tooling, but used properly, these dies can help compensate for springback. Publish date: August 9, 2005 Tech cell: Bending
	Bend allowance and springback in air bending: How to predict it and compensate for it By: Ninad Nargundkar, Hyunok Kim, and Taylan Altan This study illustrated that, when the thickness and stress-strain curve of the sheet material are known, it is possible to predict with acceptable accuracy the bend allowance, springback angle, and punch stroke to obtain the desired final product dimensions.

	2 strategies for optimizing bending operations: Do setups offline and rely on press brake controls to adjust bending parameters By: Michael Bishop, Contributing Writer Fabricators typically encounter bottlenecks during setup and production in their press brake bending operations—obstacles that lead to downtime and fewer operators actually processing material. Representatives from Amada, LVD Strippit, Bystronic Inc. addressed these issues in a recent presentation. The two largest problems? Performing non-value-added steps and having to compensate for material variations. Fortunately, some new technologies and two key strategies can help fabricators optimize their press brake operations in these areas. Publish date: January 15, 2008 Tech cell: Bending
