nx in companies that do near-folding

[Utente NX]

Bye to all,
Is there any of you who use nx and in the company bend the sheet by means of cold-rolling?

Hi.

I know companies that do it and, some of these, I started them again with ug16.

if you want some particular info, please contact me in mp, or if you think the topic may be of general character, in the thread.

Hi.

It's a topic that can interest everyone.
I would like to approach as much as possible to a development that allows me to obtain the fold as from drawing.
luck is that we do not have suppliers, we ourselves design and produce.
we started with reverse engineering and we have an excel table with the data obtained from tests on different materials, different quarries, different inclinations and different thicknesses.
now this table I must turn it into the sheet_metal_material_table.
in reading its content, it seems to me it is possible to do something intelligent, but sincerely it takes enough time to interpret it and set it up.
So I was wondering two things:
1) Is it worth it, or set the thickness and a right formula in the bend allowance formula enough and advance?
2) if it is worth it, can someone attach a sheet_metal_material_table to understand to change to our needs to speed up our tuning?

Thank you.

of similar discussions there are many around,
I summarize the two ways I followed to have consistent developments with my experimental tests.

1) what I called of the 'correct factor' and that uses the baf (bend allowance formula), going to put the parameter k in the same in the preferences of the sm (expression_sm.prt). in the formula that calculates the k is recalled a correction factor that is supposed to be equal to the thickness up to a thickness of 1 mm and equal to the thickness greater than 0.25 for each mm more than thickness.n.b. what is said is good for me because it reflects my experimental data.
2) what goes to call the sheet_metal_material_table.txt table (attached also this), whose position you must specify in the customer default. in SMS preferences choosing material go to the drop-down menu and choose the thickness.


I hope to have been clear and above all I recommend: These values are good for me. what I explain is only where to go to put your values and what method to use.

Thank you.
I was looking for a dynamic table, i.e. to vary thickness, material, quarry and flange inclination, used the correct k factor.
the table can do it, but setting it is not simple.

thanks for everything and good to make.
