Score on bend line

[jobiewan99]

I hope this is easier than I am making it out to be.....

We have some 1/8" thick uhmw sheeting that we bend at 90 degrees. Prior to bending, we score one side of the sheet 1/16" deep on the bend line. This keeps the material from springing back to flat after bending.

I need help modeling this 2-step process. I would prefer a sheet metal part that I could detail the "scoring" process in the flat pattern, and show the final product in the formed view.

Thanks in advance for your suggestions!

I'd use configurations. You could model the part as a simple extruded profile and control the fold/unfold with an angular dimension (either 0 or 90) in your sketched profile.

So I would have to manually draw a bend line on the "flat pattern" view?

If your score groove is v-shaped, wouldn't there be a line on the drawing already?

Well, actually it would be a rectangular shaped score (created by table saw blade), but that is a good point. I could dimension to the center of the notch.

I'd still like to create a sheet metal feature if possible.

Unless you use configs in a sheet metal part, you will not be able to use the groove (of any shape) because it would change the material thickness ... something which SW cannot compute.

I think you'll still need configurations, one with the score groove suppressed. I don't believe you'll be able to generate your flat pattern with an area of inconsistent thickness. If I recall correctly (and I may not) sheet metal features will barf on anything that has varying thickness.

Thank you guys for defining the limitation. Now I can quit being stubborn and finish my drawing.

Your quick responses are appreciated.
