For this part, I'm pretty sure it can be flatten before. But now I don't know why it cannot, I promise I have changed nothing. I know it is possible now when check the normal cut, but that is not what I want. Plz help, many thanks。
That's weird, I can definitely see my file attached. I'll attach it again here, but it is SW2018.
Here's an image of the tree.
Base Flange thickness should be minimum thickness at bottom of V cut.
Trick with adding material is not to join up to tangent edges of sheetmetal or the part will no longer flatten.
Turn on Normal Cut in Cut-Extrude1 & it will unfold OK. Although it doesn't look very elegant.
Kevin Pymm thanks for your quick reply. I know it's can be flatten when check the Normal Cut but that's not what I want.
I want to keep the sharp edge like I posted, and it can be flatten before. However I fail now....
beside the issue with the flat pattern … you have used pretty unlikely sheet metal parameters: Radius 0.02mm for a thickness of 2mm. How will you achieve this in real life? With this unrealistic parameters your flat pattern is useless…
It will flatten, when changing this to a k-factor of .4 e.g.:
Thanks for your remind Heiko Sohnholz, it is available after changing to bend radius to 0.7 （critical value, small than this cannot flatten ). Why it work with bend radius 0.02 mm before, it is awkward. Why is the critical value is 0.7 for 2mm sheet?
Actually in my factory it is normal process, all the sheets will be cut v groove first, then bend . So the radius should be 0.0, but it seems impossible in Solidworks...
I've got a flat pattern as well with a radius of .1 or even .02 But i have to change the bend shortening value...
And okay: You v-cutting is something special wich is normally not covered through the sheet metal functionality of SWX.
Is this a alucobond part?
It is not alucobond, our factory produce retail furniture. Almost all of the sheet (CRS , stainless steel sheet, even tube we cut v groove then bend to keep the small radius)

With all respects, but anything beyond your experience is not unrealistic.
We are a sheetmetal company and have been bending materials up to 3.2mm with Radius 0.1 and bellow.
Yes, we are doing it in real life for more than 40 years.
Obviously, we don't use K factor. We have our Bend Table for this.
Amada's Standard Radius for bending tools is 0.1mm.
You can order special tools for less than that. (though it would be a little expensive)
Yes, i really didn't know that these radii could be manufactured - thank you for sharing this knowledge. I had only the standard tools from Trumpf in mind, when i wrote this.
So - with wich toolset do you bend the radius of 0.02 mm wich was given in the realistic model? (before we knew that they make an v-cut)
You could do something similar to the attached to replicate bending a v-cut sheet. Not exactly elegant, but likely a great deal of refining possible.
Actually still works without 'cut to normal'. So attached file now a little tidier than images.
He, he, i've made a sample for that too. But i have used unfold / fold for that:
But yours looks nicer i have to say.
Bjorn Hulman Thank you , you image looks very nice, I think you forget your attached file . Can you plz show me your model feature tree since my SWX 2016 may not open your higher version file.
Many thanks Bjorn Hulman, my Chrome maybe have something wrong. I can see you attached file in IE explore... This is not a good way for me cuz it will fail if I add more bend feature. Anyway, with your guys help , I know how to solve it even I don't know the reason
No problem Richard,
too bad it won't work for you. Perhaps this could be an enhancement request?
I'm sure you could add as many folds as required as long as it's done in the right sequence.
