fold crushes in inventor

[Ing.filippo]

Good morning to all,

I have a problem in shaping a crushed fold(bordo) with autodesk inventor. the bent modeling is done correctly but when I go to create the flat model I generate an error that I cannot understand how to solve. I have intervened in changing the default dis viluppo values but I do not find how to fix the error. I attach the part and screen of the error.

Thank you.

I see you use "bend table" as a rule for the flat model. I always used k-factor.
However, it seems that the error gives it to you because in your "bend table" you did not specify the angle-roar combination that you are using in the crush fold.

you use blindfold table but I also set the k factor to use in case there was that value in the blindfold table available. but how can I solve this by using the value of k?
I had found that for values under the mm or when the thickness is equal to the fold radius it is used 0.27345, but the actual calculation I can not do it because from the production they have passed only a fold table for the values to consider. the only thing they told me for the crushing fold is that I have no recovery, so if I make a 12 mm edge in the open development I must have as result 12 mm.
How can I use this information in inventor?

It's the first time I've had a blindfold table but try to set up as in the screenshot. it seems that from the development they ask you for the crush, leaving the remain unchanged[ATTACH type="full" alt="2020-06-09 11_09_28-Style and Standard Editor [Library - Read_Write].png "658323[/ATTACH]I forgot: change the gap for the sicker. I always use 0.1mm:

I tried by inserting the values you gave me but it always gives me the same error that was displayed in the attached word with the part. If you want to use only the k as an alternative, how would you do it?

Look, I changed the post indicating the new gap.
if you want your gap (0.6mm) you need to change the radius in the bandage table from 0.05->0.3

Sorry I didn't change the gap, so in general it is worth the report that if I imposed a gap value for the fold crushes in the fold table I have to insert a ray that is half the gap value.
thanks again for the solution.
