Dimension Sheet Metal To Inside Or Outside

I think this is the better way because you can acquire your cutting length without a flat pattern by adding the inside lengths fold allowance.

Dimension sheet metal to inside or outside.

When producing drawings of sheet metal components i dimension from inside the flange walls. Critical dimensions sheet metal forming outside dimension should be used unless the inside dimension is critical. My boss dimensions from outside the flange walls and thinks this is the. Sheet metal is the metal formed into thin and flat pieces which uses sheets of thickness less than 6 mm.

Only the truly critical dimensions should be highlighted as such. 3 embosses and offsets emboss and offset dimensions should be to the same side of the material unless the overall height is critical. And also find you fold centers more easily. Hem measurement forming hems is one of those aspects of sheet metal that is very operator dependent.

The outside bend radius is equal to the inside bend radius plus the sheet thickness. Neutral axis the location in the sheet that is neither stretched nor compressed and therefore remains at a constant length. The greatest feature of sheet metal is that it s having ability to be formed and shaped by no of process. And also find you fold centers more easily.

I think this is the better way because you can acquire your cutting length without a flat pattern by adding the inside lengths fold allowance. Die opening 0 972 0 21 gives you a 0 204 in. Subtract the osos from the edge to apex dimension called on the print and you ll find exactly what the edge to outside radius dimension should be. Die opening 0 551 0 21 calculates out to a 0 115 in.

More over with variable thickness you nay not get the flat pattern. It is one of the main and basic forms of metal working. Speaking of sheet metal tool you can not control both the radius directly and more over sheet metal modelling assumes that thickness is uniform. When producing drawings of sheet metal components i dimension from inside the flange walls.

If you change the material you change the percentage. You can cut or bend into various shapes using sheet metal. My boss dimensions from outside the flange walls and thinks this is the.
