In the first article of this series, we addressed the material thickness, bend radii, flange lengths, and K-Factor features that designers should consider when producing sheet metal designs. In this article, we will look at further features and limitations typically encountered when designing sheet metal components.

Bend Relief
When producing a part with adjoining bends, special cuts must be made into the part to prevent material near the bend from tearing during the bending process. See below an example of an un-manufacturable bend with no relief and a part that has relief accounted for.
