big bend angle mistake

Hi Everybody

 

I have problem with big bend angle.

 

As you see from attached file - it 20 degree angle, and SW don't want to unbend it...

 

Material- 16GA Stainless Steel (0.063") , as per my tables- for this material bend deduction- 0.1

When I put it- SW mark bend like mistake..


Wrote to SW support - receive answer :


"The only solution is to change the inputs for calculating the bend.

In this case  it would be changing input for Bend allowance by either inputting a different  value for Bend Deduction or using a different option such as K-Factor.

Increasing the Bend radius would also allow the bend to work. Adjusting material  thickness may be a different option. "


Tried to switch from BD to k-factor (0.44) - not working


Tried to chage radius from 0.03 to 0.0625 (that tools which I have in metal shop)- same result.


Idea to adjust material thikness becouse SW can't calculate it is even not funny.

 

Please, let m eknow if somebody have REAL solution for this problen. I think, I'm not oly one , who need bend differnt , than 90 degree...


I need to receive real flat pattern, if I put numbers from the air SW will eliminate mistake, but flat pattern will be wrong...
