R&D Update: Warm-forming magnesium sheet, Part II
- Aug 18, 2017
- Article
Warm-forming die sets are much more complex than conventional deep-drawing dies because they have heating elements such as cable heaters and cartridge heaters, insulation, temperature sensors, and temperature control devices. In Figure 1 , a warm deep-drawn aluminum sheet is divided into five...

R&D Update: Twist-compression testing to evaluate friction, lubrication
- Aug 17, 2017
- Article
Many types of lubricants are available for metal forming operations, and new ones are being developed every day. Selecting the optimal lubricant for a metal forming operation is crucial to the process efficiency. For example, in stamping and tube hydroforming operations, friction at the...

Press brake basics: Bending questions from around the globe
- By Steve Benson
- Aug 16, 2017
- Article
Steve Benson goes global and answers bending questions from around the world—about plate bending in Australia, tonnage considerations in India, offset bending in Mexico, and grain direction variables in the U.S.

Die Science: Selecting radii for forming operations
- By Art Hedrick
- Aug 16, 2017
- Article
Selecting a radius for a forming operation is based in many different factors. Some of the basic ones include the material’s forming properties, drawing die and part geometry, and the amount of stretch or flow needed to make the product. Drawing or Stretching To select a functional radius...

R&D Update: Evaluating lubricants using the stamping lubricant tester (SLT)
- By Taylan Altan, Ph.D.
- Aug 15, 2017
- Article
Friction between a sheet blank and a press’s dies plays an important role in stamping parts. Fracture and wrinkling are influenced by frictional behavior, and many stampers use lubricants to reduce friction. To produce quality parts, stamping lubricants most perform at high pressures; high...

The big challenge of wind energy component fabrication
Plate rolling manufacturer DAVI hosted a wind energy seminar at its headquarters in Italy. Despite a renewed focus on fossil fuel, global wind energy initiatives aren’t blowing away—not by a long shot.

Die Science: Metal flow patterns in metal drawing operations
- By Art Hedrick
- Aug 15, 2017
- Article
The experts at STAMPING Journal are here to help you understand the metal flow patterns that can occur during metal drawing operations. Learn more here.

Die Science: Handling production splitting problems, Part II
- By Art Hedrick
- Aug 14, 2017
- Article
Possible Cause 5— Excessive Blank Holder Pressure Excessive blank holder pressure restricts metal from flowing inward. Restricting metal flow causes the metal to stretch, which could result in a split. Be sure to monitor blank holder pressure carefully, because nitrogen/gas systems can leak...

Plate rolling gets hot
- By Tim Heston
- Aug 11, 2017
- Article
Why should one consider hot plate rolling? It usually boils down to two reasons: The material can’t be cold rolled at all and meet customer requirements (thanks to cracking or other defects), or the job exceeds a plate roll’s capacity for cold rolling.

Die Science: Steel made simple, Part II
- By Art Hedrick
- Aug 10, 2017
- Article
n Value Technical: Strain hardening is represented by the exponent n in the flow stress equation, which approximates the relationship between true stress and true strain during plastic deformation of a metal. Translation: The n value represents a metal’s ability to work-harden and...

Die Science: Steel made simple, Part I
- By Art Hedrick
- Aug 9, 2017
- Article
The anisotropy of interstitial-free steel has an adverse effect on the severity of elastic recovery as well as on plastic deformation. However, adverse changes in the intergranular microstructure, such as that characterized by material with a near-isometric configuration, will result in a...

Die Science: Tooling and die training
- By Art Hedrick
- Aug 9, 2017
- Article
Human Engineering Human engineering is the single most important class a company can offer its employees. Having a tool roomful of die geniuses who don’t know how to communicate effectively is like having a Ferrari without gas. The potential is great, but you can’t realize it. The success...

Die Science: Deep drawing step by step (Part II)
- By Art Hedrick
- Aug 8, 2017
- Article
In Part I we determined that four drawing operations were required to make a cup 2 inches in diameter and 8 in. tall from 0.062-in.-thick material (as measured from the centerline). To determine the height of each draw, you must first calculate the surface area of the finished part. Figure 1...

Die Science: The big-bang theory: The causes of die crashes
- By Art Hedrick
- Aug 7, 2017
- Article
I recently had the opportunity to conduct stamping die-related training out West. During our session, we began to discuss the reasons that die mishaps, crashes, and progressive-die “train wrecks” occur. One attendee told me that his company runs high-speed progressive dies at nearly 1,000...
