Sheet Metal Details

Sheet Metal Details

Sheet Metal Details

(OP)
Hi all,

Just wondering where I could find some examples of detailed sheet metal parts. I'm detailing these sheet metal parts but my experience is elsewhere. Any good references or common detailing practices for sheet metal?

Thanks in advance

RE: Sheet Metal Details

As with all parts, it's the design intent and feature functions which dictate how they should be dimensioned.

Are outside or inside dimensions critical?

Are all features critically positioned from an edge or in groups from each other?

Do the parts have holes or features which are to be punched before or after bending?

cheers

I was looking more along the lines of common details on bend reliefs. Would you typically dimension a rectangular relief or would you just put in a note indicating that a rectangular relief is to be taken at that location?

RE: Sheet Metal Details

When detailing sheet metal, I typically have a note that states "USE MIN. BEND RELIEF AND RADIUS" then I don't worry about dimensioning it.  Also, concerning tolerances... assuming some sort of cnc process, hole to hole tolerances of +/-.010" are easy to hit.  Location relative to a bend, +/-.030" is typical.  In other words a part like "[" should have a +/- .030 on its overall hieght (inside or outside... whichever is critical).

Tighter tolerances are achievable, but will definitely be more costly.
