Tool Wear, Clearances and Burr Height
The diverse microstructures and strength levels of AHSS products present some challenges for stamping operations. Cutting and punching clearances are greater for AHSS, and as a general rule, should be increased with increasing sheet material strength. The clearances...

Tool Materials and Die Wear
Die wear is affected by, but not limited to, steel strength and surface friction, contact pressure, sliding velocity, temperature, die surface treatment and lubrication. As the material strength and hardness is increased, an increase in die wear occurs which leads to...

Case Study for Press Energy
The following study is a computerized analysis of the energy required to form a cross member with a hat-profile and a bottom embossment at the end of the stroke (Figure 1). Energy requirements increase with punch displacement, as shown in Figure 2, here energy...

AHSS Energy, Heat and Lubrication
Lubrication is an important input to almost every sheet metal forming operation. The lubricants have the following interactions with the forming process: 1. Control metal flow from the binder. 2. Redistribute strains over the punch. 3. Maximize/minimize the growth of...
