Making a Twisted Sheet Metal Part
Making a Twisted Sheet Metal Part
(OP)
In some product applications we need to make a sheet metal part that has a twist in it. How can we create it?
How should a Twisted Sheet Metal Part be modeled in NX? What feature (other than Free Form Feature) should be used?
Thanks

I use NX6.........
RE: Making a Twisted Sheet Metal Part
I've not got enough experience with Sheet Metal to suggest a route there.

I managed to replicate your model mmauldin, however law curves are vague and somewhat mysterious. I remember doing something with a sweep where the area was defined by a law curve to remain the same through difference shaped sections like a molded rubber hose on a car for instance, and for some strange reason, the area the area defined by the position of the start point of an associative curve relative to the ABS in the Y direction. What on earth is that all about?
Has anybody got anymore good examples of models that use law curves that I can pick through please?
Many thanks.
Best regards

Life shouldn't be measured by the number of breaths you take, but by the number of times when it's taken away...
RE: Making a Twisted Sheet Metal Part
Very nice, but how the heck did you figure that out? I assume that angular law is using the delta y value as the degrees of rotation, but I can't find anything in the documentation that describes it. I'm with JCBCad, any more examples, and/or documentation?
Thanks

If this meets your requirements it is possible to write a journal to automate the creation of the twisted piece.

the model is fully associative.

Solid Edge; I-Deas 7 to 12; NX4, NX5 & currently NX6.

No law curves.
Smoother than law curve version.
Maintains thickness and width.
RE: Making a Twisted Sheet Metal Part
I'd like to put my 2 cents worth in on your law curves part but I am stuck back here on NX6.

For mauldin, FrankSwinks and eex23:
Could you gentelmen, please, resend your links for NX5 or NX6? I do not have access at NX7 or NX7.5!
Thanks!
cowski: Thanks a lot for your attachment; It has been sent for NX5 or 6 and worked perfectly!
JCBCad (Mechanical):Thanks for your comment.

I think the through curves is simpler then the layer 4 option however if you wish to modify the shape to have it closer to reality (if that is important) then this can be done by moving the three internal spline poles for each of the four splines. You can certainly see the difference between the G1 and G2 examples.

As for controlling thickness, the models I submitted are created by first making a sheet and then adding thickness, so they are by default, within the tolerance setting, controlled for thickness.
