Bend line the line across the metal where the punch comes in contact with the metal and the bend begins.
0 5 cos α the total area.
Over bending stretch forming coining or bottoming the punch.
A rain gutter is formed by bending up the sides by x inches of a 30 inch wide rectangular metal sheet as shown in the figure.
Bump bending also known as step bending the process for forming a large radius with conventional tooling by performing a series bends in close proximity.
It is one of the indexes of metal strength.
It is the maximum stress that the sheet metal material is subjected to before pulling out.
