Sheet metal bending is a metalworking process used to permanently deform and bend sheet metal into various shapes and angles by applying force.
Sheet metal bending allows for producing a wide variety of part geometries like bends, flanges, channels without the need for expensive tooling required in processes like stamping.
Advantages include speed, high accuracy, reduced post-processing, lower part weight, and cost-effectiveness compared to alternatives for lower volumes.
Design considerations include bend radius, bend allowances, bend reliefs, material properties like springback, and part geometry.
Quality control through processes like first article inspection, statistical process control, and capability studies ensure consistent bend quality
The two main methods of sheet metal bending are:
a) Brake press bending: The sheet is clamped and bent over a V-shaped die using a punch.
b) Roll bending: The sheet passes through a series of rolls that progressively bend it
