To think about bending a sheet of metal that has appreciable thickness focus on an imaginary central sheet the so called neutral line or neutral axis within the thickness.
Bending for sheet metal.
The inside bend radius should be equal to the thickness of the material that you re forming.
This neutral line.
Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal.
If you re bending 0 020 thick material use a 0 020 radius.
Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.
Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.
Commonly used equipment include box and pan brakes brake presses and other specialized machine presses typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.
Bending is one of the most common sheet metal fabrication operations.
The force must exceed the material s yield strength to achieve a plastic deformation.
