Hi all
I'm looking to make holes in a bent (or rather curved) part. This operation should not be done unfolded because it is when it is folded that I know the positions.
Then, and this is where it gets tricky, these holes must be perfectly round and perpendicular to the front of the unfolding in order to be machined via SWOODCAM.
Thank you for your help.
Hello
You can't either:
- a plane tangent to your sheet metal that would be perpendicular to the axis of your drill?
-a coaxial axis to the axis of your drill and from there you draw the diameter of your hole with the material removal function with revolution?
I propose this, these are the ideas that come to mind like this at first sight.
Kind regards.
Or drilling with 3d sketching it must work.
Can you join the room that we see what we can do?
Hello
What version of SolidWorks are you on???
See if my piece can bring you anything... Piece in SW 2016
First of all, thank you for your answers.
AC Cobra, in the idea, this is the result I want to obtain but the piercing is distorted by unfolding. As a result, it is not a circle that is detected and the drilling cannot be done on a machine.
Tomorrow I will try the other solutions proposed by Fab camp and sbadenis.
The elliptical shape or egg which is given after unfolding is done by laser cutting or oxy-cutting to precisely achieve a result of the diameter of the hole to be able to insert a tube or a puncture that is positioned on it or in a quarter quarter...
I work with wood with digital routers. My tools are drill bits for a Ø3 drilling.
I think it is not possible to get the piercings directly. I think of another solution:
- point my holes in the assembly and then make the defined holes on the unfolded.
On the other hand I don't see how I can point....
You make a diam 1 in your curved piece, then you unfold it and you place your diam 3 on diam 1.
Thank you!!!!!
This solution suits me perfectly. I made a Ø0.5 hole because the Ø3 holes are tangent to the Ø0.5. In wood, it's not within 0.25!!!!
Make a hole Ø1 on the bent workpiece, unfold the workpiece (with the unfold function and not unfold), drill the hole to the correct diameter, fold.
Grill the time to do tests: impossible to recover the axis of the hole after unfolding to make concentric
It's true but you can convert it into a sketch in the unfolded and with it define the center with a sketch line and place the hole there....
I had started with a transition fold, as I couldn't get the center of the hole, I tried to make a square hole (starting with the idea that the point of intersection of the diagonals would be invariant), Sw didn't want to unfold anymore.
By the way, I couldn't use the unfold function with the transition fold.
For the transition folds you have to tinker! Make a small 1mm chamfer at the end of one of the edges then use it as a fixed face to unfold it and then you will have to recreate it again for the folded.
Astute.
On the other hand, on a "real" transition fold, it doesn't work: impossible to select the chamfer.
I tried by adding a fold on one of the edges, the same.
Funny thing, the shape of the "square" cutout
in close-up
The sketch is on a reference plane, the "normal" cut.
with this cut-out, the part does not accept either of the 2 unfolded or unfolded commands.
