A common problem in both the sheet metal and plate industries involves parts designed with an inside bend radius much tighter than necessary.

In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. Edge bending is another very common sheet metal process and is performed with a wiping die.
