Designing a sheet metal weldment that uses parts with a 16 inch bend radius in 14-gauge 304 stainless. Will be roll-forming these parts.

Created the details using lofted bend sheet metal function. Afterwards I open up the feature and I'm concerned about what Bend Parameters to use.

 

Inside Bend Radius? (for some reason the default is .029 in.) Does this value matter?

 

I believe that the only important value in this case is the Bend Allowance K-factor.

 

From your experience, what is the best k-factor to use and what about the value for Inside Bend Radius?

 

Thanks much for your help.
