I'm wondering where I can get sheetmetal design tables that are already set up for different metals, thicknesses, etc.?
Sheet metal design tables will vary depending on the type of bending, tooling, and material being used. I would recommend that you perform testing on various thicknesses, material types and tooling that you typically use, to acquire an accurate bend deduction (K-factor) and then setup your own tables reflecting your findings. I hope this helps.
All of our sheet metal fabrication is farmed out. We had those vendors supply us with the specs they use for their own designs and each of the vendors is slightly different, as Robert states due to tooling differences.
