Problem of unfolding, cutting not faithful to 3D

3D Design Volume Model

Hello

 

on a sheet metal part, a bias cut on a radius is correct on the 3D but is replaced by a straight cut on the unfolded, and therefore the exported DXF.

How to get the dxf faithful to 3D?

Solidworks does not handle bias cuts on sheet metal edges.... Sorry.

 

The software thinks in such a way that it can machine the part in 3 axes and not 5...

If you want it to appear, you have to create the bias of the flat piece and then fold the whole thing

Unfortunately this is normal, in SolidWorks it is not possible to unfold a sheet metal whose thickness would not be constant. SolidWorks therefore automatically corrects this "thickness change".

Basically, this "chamfer" is a post-cut function for SolidWorks.

Now you can call the unfold configuration of your 3D and then add a function that performs the "Chamfer" in this configuration.

If you fold the part back, this function will automatically be switched to the delete state.

However, this part does not need 5 axes to be cut on a plasma table!

by creating an Unfold function on the offending fold it manages the cut well and displays it correctly flat, on the other hand I can't pass it on to the dxf.

 

Small clarification: I don't need the chamfer, I need a normal material removal. I just want to get the curve of the cutout on the dxf.

Hello

If you think that there is no need for 5 axes, it means that your 3d is wrong. In your case, I would do the opposite, flat construction, so without angles, and then I would fold in 3D afterwards.

There we will stick to reality I think.

Edit: to be more precise, unfold just after the first function, remove the material and then fold

To make a plasma or waterjet laser cut by cutting an edge at an angle.

 

Without the 4th axis, I don't know how you can do it.

 

Inevitably, your cut will have an X, Y, Z and Z1 coordinates for the inclination.

 

If you want it to work, you will have to uncheck the normal material removal box, but then logically your part will no longer unfold...

Ha it's on the DXF but your unfold is right because at home with your part it's not unless I uncheck by editing the unfolded function the "simplify the fold" box.

And in this case the dxf is just right
