Sheet metal non uniform thickness

Hello,

I am into the filed of creo Automation using Toolkit.  I am into sheet metal group. For thickness of the part, is it okay to go with the assumption that thickness of all features inside a part tree (Flange, Flat, Extrude etc.) remains constant?

If not so, It will be better to have some example of varying thickness.

Regards

Ketan

I'm not sure how you would get extra material on a sheetmetal thickness, unless some sort of spray metal disposition application. If that was needed, I would do it after the part is formed as a secondary process.

Holes, slots or a contoured shape cutout are the only methods for removing material from a sheetmetal part, without doing things like acid dipping to reduce the thickness in places.

I suppose you could do a hem-edge to double the material thickness before bending, but that might be hard to model and even harder for the flat pattern algorithm to understand the bending procedure.

Sheetmetal parts should always be a uniform thickness. You are bending a single piece of metal cut from a bigger sheet. Most flat pattern programs do not work if the material thickness is not uniform.

    Correct... I was inline with your point... Then I came across  a point of having extra material at some place where it is not really required... Is removing extra material by cutting material in the form of hole or slot is the only option in this case??
