The following sections detail the most common and effective methods used in industry today. Factors Influencing the Bend.
Press Brake Setup for Consistent Bends
The primary advantage of air bending is its flexibility—it allows for a wide range of angles and shapes using a single set of dies. Bottoming and Coining Unlike air bending, bottoming and coining utilize a process called "bottom-out" to achieve specific, sharp angles with high precision.
In this process, the punch presses the material into the die, but it does not bottom out; the metal bends solely on the force of the punch entering the V-shaped die. Coining goes a step further by applying pressure that exceeds the proportional limit of the material, causing the metal to plastically deform and compress between the punch and die.
Press Brake Setup for Consistent Bends
This discipline relies on specific principles of physics and material science to predict how a sheet will react to applied forces. Bend Allowance defines the arc length of the neutral layer within the bend angle, representing the material that is stretched during the process.
