internal radius fold sheet

[Therapy?]

hello to all

I would like to ask you if when I make a fold on the sheet end I can define with a value the inner radius of fold this because as options I see only "no radius" "r=spessore" "r=2*spessore" in reality usually on thin sheets sp.0.8/1/1.5 if I don't remember badly the inner radius of the knives is 0.5 but I can't set it

provided that in years that design sheet, the fold radius of knives, should never be lower than thickness, otherwise you have a stretch that can lead to cracks that at least spoil the aesthetics of the piece (not to mention mechanical resistance).

However, if you place yourself in the cell where there is written thickness in parentheses [ ] and delete the writing, you can enter what value you want.

I have some doubts.... How many years?
However I confirm that taking some pieces that I have in the house and drawings of our customers who work sheeting have internal radius 0.5 even on thicknesses 2 (bearing fact) with the plates I worked on several years ago and I remember for thin thicknesses to have used always r0.5 (but I had solidworks)
on molded sheet metal pieces never had problems with internal radius 0.5

I started in 2001 with the sheet form; that then some suppliers propionate you to lower rays, it is true, but I always disputed the thing, even because with some high resistential materials, if you do not follow the specifications (that with hardox 400 or domex 700 you go also to 2,5 times the thickness), you will never have the characteristics indicated.

Hi.

I also have always used the internal radius half of the thickness for both iron and aluminum sheets, and so doing I have never had problems both for the folded parts in our interior and from external suppliers. to do this at the beginning I had to correctly set the k value of the material.

perhaps speak of different sectors and materials.
for carpentry/structural sheet is true what you have reported, the radius cannot be lower than the thickness.
for the furniture industry do a little as they want, because they use low carbon steel that also bears plastic deformations in the radius area without big problems

 

[320i S]

Yes, I agree.

However in creo you can set the radius with a numerical value, provided it is greater than zero.

That's right.
