12. Edge Conditions of Formed Parts

1. "As Formed" - This is most common and is formed from a controlled size and shape blank.
   
2. "Die Trimmed" - This is usually simple die trimming and parts have edges similar to flat stampings.
   
3. "Hemmed Edge" - This is formed for smoothness and stiffness.
   



4. "Curled Edge" - This is formed for maximum stiffness and smoothness.
   



5. "Lance-Formed" - Edges are likely to have more burr than flat stampings.
