bending table (k factor)

[mirco borghi]

Hello, everyone.
I wanted to know if someone had already drafted a folding table for steel sheets.
to have an idea of how to set a custom.
Thank you.

Hi, Mirco.
If you use the basic sheet module, there is no possibility to create a fold table, but you can only in development decide a k to be used for calculation.
if you use the advanced sheet module (to understand what costs almost as much as the basic module of element direct creo intended mainly for those who do sheeting from morning to evening) then in that case you have a configuration file, or rather a workshop file where you can define the fold tables by binding them to the materials you use, thicknesses and fold tools. the thing is very interesting but also quite complex to do because within the program you find an example scheme that goes all built according to the machines and equipment you have in the workshop. the program is done in lisp, for example if you have a trumpf bending machine and the software properly configured can even pass directly the 3d model to the bending machine.
if it can be useful to you I can get you an excel file that I had done a little time ago for calculating factor k on the basis of rule din6935.
a greeting, stefano

hello politely send me the excel file

the same discussion was dealt with for solidworks and inventor. I remember that it depends a lot on the type of folding tools you have in the workshop, so the table is very personal. tool radius, thickness, distance supports v prism or other shape characterize strong differences.

I needed to compare my data. .

Hi, Mirco.
If you look in the configuration files/s, you will find a table, sha_demoshop, which is the reference table for bending steel plates. you can insert multiple workshops and different materials according to the chosen bending process. fold in the air, fold by contact, etc. ... definitely the method that I recommend is to directly impose the value of withdrawal measured according to the materials and pairs knife/cave available in your workshop. in online help are the examples and formulas used in the calculation (which takes place according to din rules)
greetings,
