Keynote: Stamping Tooling Technologies to Accelerate Innovations with GigaPascal Steels
Use of advanced high-strength and ultra-high-strength steels is growing rapidly in the automotive industry, to help meet stringent fuel-economy targets, enhance occupant protection and improve crash performance. While these steels provide optimal performance by providing excellent strength and ductility, from the perspective of die wear and tear, they require use of special die materials and surface treatments. Learn here about die-wear behavior when stamping higher-strength steels, and how to avoid costly die repairs and press downtime.

Introduction to Simulation Technology
This presentation covers the two basic simulation technologies: the inverse (one-step) method and incremental methods. The attendee will understand the difference between these technologies and when it is appropriate (or best) to use each.

Roundtable Discussion: Ranking Method of Progressive Die Strips
The first step in processing a progressive die is to develop a strip layout. All too often only one strip layout is created. Even if several strips are developed, how does one determine which is best? This discussion centers on how metalformers/die designers can rank strip layouts so the best possible strip design is chosen.
Facilitator: Peter Ulintz, PMA Technical Director
11:00 a.m. Die Kinematics and More
Furthering the discussion on die simulation and animation technology and its application, including collision detection, Ray Proeber, president and owner of Accurate Die Design Software, Inc., notes that progressive and transfer dies can be simulated in various press types. These include conventional, servo and link-motion presses, as well as fineblanking, fourslide, multislide and Bihler machines. Also important to understand is the ability to predict slide-tipping and reverse-tonnage loads.

Proeber contends that a dozen years ago, die simulation merely was animating the strip itself without showing what was actually happening in the die. "There was no interaction between the die components or even between the die components and the strip," he says. "Today, several simulation-software packages display very realistic die-operating conditions.

"When people hear the word simulation, they often get nervous thinking that the software will be difficult to learn, to set up and to pay for," Proeber continues. "This is not always the case. The time savings downstream typically pays for itself many times over, based on the ability to detect collision problems and clearance issues before the die ever enters the press—much more efficient than catching and fixing problems later."

Today, nearly all 3D software can detect static interference--that is, interference when the die is closed, Proeber explains. But in order to affect the bottom line during the die build and really minimize debug and development time, the designer must be able to detect interference and collision as the die is operating and as the strip is lifting and advancing.

"Further, reverse tonnage and slide tipping can wreak havoc on a punch press," Proeber adds. "Unfortunately, they often are overlooked, sometimes until the press must be rebuilt. Reverse tonnage in particular—also known as snapthrough or negative tonnage—can impart significant damage to a press in short order. And, while slide tipping is not as destructive on the entire press as is reverse tonnage, it easily can be addressed so that presses remain in good condition rather than suffering unnecessary, premature wear."

Software Tools to Support Machining and Other Die-Making Processes
What if shop standards could be incorporated into every new die design and build project? What if the design decisions could carry such weight that it would even affect the way the die is built and machined? Die-design software not only supports strip and tool design, but also can help to ensure that the tool will be machined as intended.

Case Study: Development and Optimization of a Deep Drawn Transfer Case Cover
This presentation looks at the development of a deep drawn transfer case cover (for an automotive powertrain) from a one-step simulation through several incremental simulations and eventually to soft tool validation and final production optimization.
