Choosing the wrong size blank under estimating the number of forming tools required or encountering an unexpected wrinkle or split can be very costly if only discovered during first physical tool tryout.
During bending operation the metal on the inner side of the neutral plane is compressed and the metal on the outer side of the neutral plane is stretched.
One of the primary defects that occurs in deep drawing operations is the wrinkling of sheet metal material generally in the wall or flange of the part.
