How does a bending machine typically achieve metal deformation?

A bending machine typically achieves metal deformation through the use of a die and punch system. In this process, the workpiece is placed between a stationary die and a moving punch. As the punch applies force, it pushes the metal into the die, creating the desired bend. This method is particularly effective because it allows for precise control over the angle and radius of the bend, enabling repeatable and accurate results.

Using a die and punch system is a common practice in various bending applications, such as sheet metal forming, where the geometry and thickness of the material can be critical for the performance of the finished part. The advantage of this approach lies in its ability to handle different materials and thicknesses while producing consistent shapes, which is essential for many metal fabrication processes.
