Sheet metal bending is a common process in aluminum fabrication. It involves shaping a flat sheet of aluminum into a desired three-dimensional form by applying force to the material. Here's a general overview of the sheet metal bending process for aluminum fabrication:

1. Material selection: Choose the appropriate grade and thickness of aluminum sheet based on the desired application and requirements. Aluminum alloys such as 3003, 5052, and 6061 are commonly used for sheet metal bending due to their excellent formability and strength.

2. Design considerations: Determine the dimensions, angles, and bend radius required for the part. Consider factors such as the material's elasticity and spring-back behavior to achieve the desired final shape accurately.

3. Tool selection: Select the appropriate bending tools for the specific bending operation. The main tool used in sheet metal bending is a press brake, which consists of a punch and a die. The punch applies force to the sheet metal, while the die provides the necessary shape and support.

4. Set up the press brake: Adjust the press brake's settings, including the tonnage (force) and back gauge position, based on the material thickness and bending requirements. The tonnage required depends on the material's strength and thickness.

5. Marking and positioning: Use layout tools like rulers, protractors, or templates to mark the desired bend lines accurately on the aluminum sheet. Proper alignment and positioning are crucial for precise bending.

6. Bending process: Place the aluminum sheet on the press brake's bed, aligning it with the marked bend line. Lower the punch onto the sheet metal, applying the desired force to bend the material. The aluminum sheet will deform plastically along the bend line, creating the desired shape.

7. Multiple bends: For complex parts requiring multiple bends, repeat the bending process, adjusting the back gauge and repositioning the sheet metal as necessary.

8. Quality control: Inspect the bent part for accuracy and quality. Measure the angles, dimensions, and straightness of the bent section using appropriate measuring tools. Make adjustments if needed.

It's important to note that the specific bending techniques and parameters may vary depending on the equipment, material thickness, and complexity of the part. For more precise guidance, it is recommended to consult with an experienced fabricator or refer to specialized resources on aluminum fabrication and sheet metal bending.
