In an era of automation, the job of the die maker has shifted from manual machining to troubleshooting. Ostergaard’s principles give you the diagnostic ability to look at a failed part and say, "The stripper plate is hitting too late," or "The die clearance is wrong for 304 stainless."

This paper condenses and expands the core, practical die-making knowledge found in Ostergaard’s Basic Diemaking into a detailed technical reference: materials and heat treatment, clearance and edge geometry, die types and components, press tonnage and strip layout calculations, forming/drawing theory, progressive/compound die design, maintenance, troubleshooting, safety, and modern CAD/FEA/CNC methods. Use the worked examples and rules-of-thumb as starting points and validate each die with prototype trials and ongoing monitoring in production.

When the punch contacts the metal, the material goes through three distinct phases:
