K-factor problem with the transition bend tool on solidworks

Good evening

 

I'm having a problem when I use the -factor with the transition bend tool. Namely, I was taught to use k-factor set to 0.5 when you want to develop a ferrule, a cone trunk... I'm trying to develop connoids (a kind of oblique cone trunk). When I model it with the transiotion fold tool and the k-factor set to 0.5, it develops the part as if I were developing it outdoors without taking into account my k-factor parameter 0.5. So I changed the k-factor to see if my length expand change as well. When I do this nothing happens, that is to say that my developed length in the unfolded state does not change even when I vary my k-factor. Has anyone ever encountered this kind of problem? How to have the right develop (so with a neutral fiber).  Thank you in advance, cordially Maxime

Hello Maxine,

I'll put you a small file with the answer. Check if the sheet metal boxes 1 are checked and if so, uncheck them.

Regards Manu and if not put your coin in the answer

Hello

The K factor is not always at 0.5. It depends on  the thickness of the sheet, the vee and bending radius, see the attached word file.

May the force be with you.

Hello

I also use the same word document from OBI WAN, and I'm happy with it.

Good luck and don't turn to the dark side.

It also depends on the size of your part, for a small room with a large radius, the developed will not change much between a k factor of 0.5 or 1.

If not, it is possible to get a glimpse of the room?

Thank you very much obi wan for this file, I thought that when working in small thickness, i.e. under 15mm we always set the k-factor to 0.5...

But that doesn't answer my question of why when I change the k-factor with the transition fold, nothing happens.
