Thera are some feature to automatically set K factor in function of Thickness and BendRadius?

Luca_Loretti

I would like that Onshape give me the exact K factor while I'm modeling sheet metal part when I insert thickness and bend radius. How can I do that ?

This isn't supported in sheet-metal yet. but I have an easy workaround i use on a daily basis.
FS:Sheet Metal Bend Table | Test (onshape.com)

make a copy of the above document

download the CSV and edit it.

if you add more rows, make sure you add those rows in the code as well

re-upload the CSV by selecting the 'update' option.

now just insert this feature before any sheet-metal feature then you can just use the variable "thickness" "bendRadius" and "kFactor" in the sheet-metal feature.





you can see here that this just adds those variables into the part studio,
there in an option to put a prefix in front of the variable name if you want to set some thickness standards for the entire project.

@Luca_Loretti, is your intent to create your own custom k-factor lookup table?  Because my understanding is that k-factor is very much dependent on material properties and tooling.  You (or your sheet metal vendor) will likely have to run a series of bend tests to determine the relationships between material/thickness/bend-radius/k. 

Hopefully @bryan_lagrange or one of the other sheet metal gurus in this community will chime in and correct me if I'm wrong.
