Sheet Metal Roller Bead

Visitor

Sheet Metal Roller Bead

I want to add a bead to a sheet metal part. It will follow the contour of another feature already placed. I could do a form tool and punch it in the part but I was hoping there is another way. I would like to sketch my trajectory on the part and have a the shape sweep that. But so far I dont see a way.

Here is a sample picture of something like I want.

This would be the tool that would do it,

Re: Sheet Metal Roller Bead

I am not a fan of the punch tools since they are kept outside the model. I opt for a surface form tool.

That way I generate the surface just like you suggest and then using the surface to form the metal isn't too troublesome at that point.

You can therefore use all your familiar commands to create the surface including reusing common references.

Interesting tool - I like the video

The Mate Rollerball™ tool creates stiffening ribs and decorative beads in sheet metal parts without a secondary operation. It is available in popular tool styles including: Ultraform for Thick Turret, Thin Turret, 112/114, and Trumpf style.

Re: Sheet Metal Roller Bead

Sorry about the link. I didnt notice the extra http remaining after I cut and pasted.

Looking at other cad packages It looks like they have a feature specifically for beads. I dont see this in Creo. I dont like form features either but since it would take more work to make the feature come out correct without a form tool , and I will be needing a very similar feature in a few other other parts Im afraid the form tool is what I will have to use. PTC reallly needs to add funcitonality for a bead feature. Thanks.

Re: Sheet Metal Roller Bead

I just made a quick look for beading in other packages; only found it so far in NX NX Sheetmetal 18 BEAD - YouTube and SolidEdge Solid Edge Short: Sheet Metal in Solid Edge ST6 - YouTube courtesy of a compliant that Inventor did not. Overdue Improvements to Inventor Sheet Metal: - Autodesk Community which is a really interesting list of things for sheet metal to do. I did notice that the Solidedge version is unrealistic in its handling of sheet metal - the beads would certainly collapse if they were bent like the model shows.

Re: Sheet Metal Roller Bead

i think the sketched form tool is your answer. they have added that from creo 2.0.

you have to just sketch the shape..it has to be closed sketch.

Re: Sheet Metal Roller Bead

I never figured out how to correctly use the sketched forms.

Ken, the feature is there, it just isn't prettied up like other offerings.

A path, swept arc, and quilt form. Done:

Re: Sheet Metal Roller Bead

Ok this looks promising. I have not tried this method before and so far I must be missing something as I cannot get it to work.

Here is my panel with the swept surface along the sketched trajectory (the cutout on the left). The straight bead along the bottom I did with a form tool.

When I get in to Quilt Form and select the surface previously created I cannot get it the create the sheet metal feature I tried various combations of the options. Thanks for the help with this.

Re: Sheet Metal Roller Bead

Make sure the quilt goes through the material thickness.

Be sure to radius your corners so the quilt doesn't double back on itself. (just guessing here)

Re: Sheet Metal Roller Bead

...and try switching the direction arrows on the form feature creation
