Surface defects is an important issue in sheet metal stamping as the stamping process affects surface appearance and thus influences surface quality.
Defects in sheet metal forming process.
During the rolling process a piece of metal will experience a different amount of reduction in certain areas of the piece.

Chapter 6 sheet metal forming.
Spring back can be calculated approximately in terms if radii ri and rf ri rf 4 ri y et 3 3 ri y et 1 spring back increases as r t ratio yield stress of material increases as elastic modulus e decreases 14.
Wrinkles splits and springback are the three most common defects.
As a result during the product development process much attention is paid to avoiding defects on surface appearance and the resulting surface quality.
This can cause an uneven roll with various amounts of pressure throughout the piece.
