1. • Elastic deformation of metal sheeting

     • Press brake bending involves the elastic deformation of metal sheeting under the pressure of the upper die or lower die of a press brake machine, followed by plastic deformation. At the start of plastic bending, the sheet is free to bend.

   What is the inside bend radius of a press brake?

   • That circle (and, hence, that bend) should have an inside bend radius of 0.120 in. When a press brake bends, the metal elongates ever so slightly. This has to do with the nature of compression and expansion on the sheet or plate as it’s bent. Consider the cross section of the sheet metal thickness in Figure 3.

   What are the key principles for effective press brake bending?

   • Key Principles for Effective Press Brake Bending: Sequence optimization: Bend external angles before internal angles to prevent interference. Prioritize complex geometries: Form special, non-90° shapes before standard bends. Strategic planning: Ensure each bending step doesn’t compromise subsequent operations.

   How does a CNC press brake work?

   • The final bend angle is precisely determined by the penetration depth of the upper die into the lower die cavity. A CNC press brake’s primary functional components include: Back gauge: Controls the positioning of the bending line with high precision. Upper die: Applies the bending force and helps shape the outer radius.
