Leads to large burrs, heavy deformation, and distorted part edges.
Before running a job, a toolmaker must ensure the press has enough tonnage to shear the metal. The formula to calculate required cutting force ( F=L×t×τcap F equals cap L cross t cross tau = Total perimeter length of the cut (inches or mm) = Thickness of the material (inches or mm) = Shear strength of the material (psi or 5.

Because dies endure millions of high-impact cycles, they must be fabricated from specialized materials, primarily . Tool Steel Type Characteristics Common Applications O1 (Oil-Hardening) Low distortion during heat treatment, easy to machine. General blanking dies, short-run tooling. A2 (Air-Hardening) Excellent dimensional stability, high wear resistance. Progressive dies, medium-to-long production runs. D2 (High-Carbon/Chromium) High wear resistance, retains edge under extreme friction. Heavy-duty stamping, abrasive materials. Carbide Extreme hardness, brittle but practically immune to wear. Ultra-high volume electronics or coin stamping. 6. Layout, Maintenance, and Troubleshooting
