Bends on manufacturing drawings refer to the specified locations where a material, usually sheet metal or similar materials, is to be deformed by bending to create a specific angle or shape. The drawing will indicate the bend's radius, angle, and direction of bend, often using symbols and reference lines to show where and how the bending should occur. For example, a part may require a 90-degree bend with a 5mm radius at a specific location to form a bracket. Properly specifying bends ensures that parts meet design requirements for fit, strength, and functionality while optimizing the bending process to avoid material defects like cracking. Accurate bend specifications are essential to ensure the part performs as intended during assembly and use, especially when forming complex shapes or ensuring proper dimensional accuracy after bending.
