Variable thickness along the edge

C

Dear all,
I have some diffuculty in adding thickness along
the edge of the revolved surface (thickened
one).Basically the revoled surface thickened to 6 mm. And
an elliptical cut created on the one end of the revoled
surface. I want add 2 mm thickness on the edge side and
that should gradually reduced to zero and merge with the
exising surface.

This variable thickness added to increase strength along
the edge for bolting.

Please see the image in the attachment.

First i tried this using sweep feature using edge as the
trajectory. But i couldn't get exactly what i want. (that
means it not merge with the exisitng surface). I found
some gap between the sweeped one and the exising surface

Can anyone tell me how to do it.

Thanks.

Dear all,
See the Variable thickness image in this post.
sorry. missed in the previous post.

Thanks .

S_pme20,
I have reattached the image in the initial
post.Pl.have look and give your suggestion.


Thanks,

is it possible for you to upload an pic using the View attachment 5416instead of in a .rar file?


it sounds like you want a sweep and controll it with a relation using trajpar. But since i cant see the pic, i cant help you more.

tobbo,
All the time i used the same icon to upload the
image. I don't know why the image is not uploaded till.

sweep wedge like section along eliptical cut edge...
overlap sweep section inside existing eliptical section to ensure not to have any gap..

OR

you can try by giving draft with hinge plane at merging line
Edited by: s_pme20
 
I would do this using surfaces, you have an offset at the outer edge and the intersection at the thin egde of the wedge, boundary blend this and the same with the other three sides, merge and solidify.

might work using vss but I'm sure the above is simpler
 
One more way.
Draw in in the curves you want as the boundaries. (as you have penciled in)
Use boundary blend for the curved surf.
Modify the edge condition as needed.
use fill for the flat sides (hard to tell if there are a few)
merge surfs
solidify
round up the edges
done

Having said that.
VSS will get it done in far fewer clicks and will be much worth the investment in time to figure out how to make it work, but if you have a deadline and are not afraid of a whole lot of clicking to trudge through this will be easy.
I am just learning how to make VSS do what I want now. The only way i was able to make it do anything was to try many different approaches unlit I started to see how the tool works. VSS is now becoming my swiss army knife.

Good luck,
Chris
 
upload the part so we can try the different alternatives. I bet i could be done in one Vss using one origin and one trajectory, and then specify the tangency to the surf where the origin is located.

Oops
I did not read one of the posts and see I suggested the same method.
I love VSS now that I get how it works. But it ate up 3 hrs or so to make my first good use of it. Then on further inspection I found the cutting surface I made did not keep it's orientation the way I thought it would and invested another stressful 2 hrs as the part had to go out for quote.

Regards,
Chris
