Tool Wear, Clearances and Burr Height

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

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

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

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...

Hot Forming Process: Direct and Indirect

Hot Forming Process: Direct and Indirect

As promised, in this blog we’ll review the Direct and Indirect Hot Forming processes. The goal of hot-forming is to achieve complex geometries and part consolidation at strength levels previously unimaginable, while minimizing springback and distortion. While several...

Hot Forming Overview

Hot Forming Overview

Today many product designs tend to combine geometry complexity and part consolidation with the highest possible final strength steel required for in-service applications. Maximum part complexity usually requires superior stretchability as evidenced by high work...
