Slotted Hole Drilling on Bent-Sheet Metal

3D Design Sheet Metal / Machine Welded
1

Hello,

I'm trying to make slotted holes on a bent sheet metal. After some research and testing, the best solution seemed to be to unfold my sheet metal, perform the extrusion (the holes), and then use the bending function.

Unfortunately, I'm stuck at this last step. I can't fold my sheet metal: an error message appears: " Reconstruction error: This part contains functions that cannot be unfolded." 

Thank you

Hello and welcome;

Be sure to specify which version of Solidworks is being used.
And, a screenshot would not be refused...

This allows you not to download the part if our versions of Solidworks are older. (I have Solidworks 2022 and obviously you are using a higher version)
And this makes it possible to improve the quality of any responses...

Since I can't open your component, I'm responding blindly.

  • It is a good practice to unfold the sheet metal before drilling the holes.
  • Pay attention to the conditions for the end of drilling, regardless of the type of material removal used (Drilling wizard? Extrusion?) … I prefer the piercing assistant. It is preferable not to use " Through everything " but to link the depth to the thickness of the sheet.
  • It is also sometimes interesting to use the " normal to " option, especially if the angle of the sheet to be drilled is outside the reference planes (X,Y,Z)

Regards.

Hello,
SW manages very badly the removal of material in the folds, that's nothing new...
For a stupid trunk like your piece it seems almost impossible to me, unless you start the construction in another way (your construction is logical, SW less so):

And not even sure that we can achieve the desired result...
Good luck!

I think the same thing, it's the method of building the transition folds that puts the souk, using another method to form the cone tonc it works

Hello, I'm using the 2023 version, so I can't see the construction tree, can you tell me the settings you changed?

Thank you for your answer but I can't understand the difference in parameter between your construction tree and mine

Yes way of building does not please Sw (2023). Even without material removal, sw can't fold your workpiece.
