What is the rule of thumb for sheet metal design?

Views: 243 Update date: Feb 20,2024
A common rule of thumb in sheet metal design is the "Rule of Sixes," which states that for bending operations:

1. Use a minimum bend radius of six times the material thickness.
2. Use a minimum bend relief width of six times the material thickness.
3. Maintain a minimum bend distance of six times the material thickness between bends.

This rule helps ensure that the material can be formed without wrinkling, tearing, or other defects, and it promotes uniformity in the design process. However, specific design considerations may vary depending on factors such as material type, equipment capabilities, and desired final product characteristics.
