Is there a PhysicalProperties.SurfaceArea for sheetmetal?

Is there a PhysicalProperties.SurfaceArea for sheetmetal? or something that would give me the total used square footage of a given sheet metal psm? I need to exstract this value from the psm.

As of two years ago, the answer to this was "No". I'm subscribed for a current answer, though.

Hi @ngardner

Hi @Chally72

 

 

as it would help, You can use my macro MainDim.

 

This macro calculates the CutSize Area for any PSM part and write it as an exposed variable

So this at the moment is the rectangular area of the flat pattern not the real aera.

 

But I will try to midfy this macro for calculating this value too.

 

In the meantime You can put Your on variable into the table using the total area of the part minus cut length multiplied by the thickness and divided by two.

 

This at least will give You one surface value for the bend part, not the flat pattern.

 

I keep You informed if I was ablt to modfiy my MainDim macro.

In general, no.

 

However, if you are trying to estimate sheets to order material for the job. The flat pattern cut size X and Y are useful.

 

specifically:

Flat_Pattern_Model_CutSizeX

Flat_Pattern_Model_CutSizeY

 

That I loosely call CutX and CutY

 

I use columns in the parts list to display this.

Hi @12GAGE

 

 

and this is what my macro MainDim is calculating as area.

 

Cutx multiplied by CutY gives CutArea

 

And as You have said, for cost analysis I also would suggest to use that value.

Normally You have tu use this rectangular area of Your gage for producing that piece of sheet metal.

 

Must users I know are doing just this.

I can't remember if volume is exposed or not, but if you needed more accuracy than X.Y you could do something like Vol/thickness = Area or (Mass/Density)/thickness = Area

Hi @Alex_H

 

 

 

Volume must not necessarily be exposed, it still is an variable which can be used for a variable calculation 
Gage Area = Volume / Thickness

 

At least this results with trhe area of the bended psm, flat pattern differs a little, but I think this could be ignored

 

Good post by You!

Hi Edgers,

Hi @ngardner

 

 

 

I have just updated my MainDim macro by the enhancement of calculating the true area of the flat pattern!

 

 

So see attached ZIP file of the macro, read the two XML files (where evrything could be defined and named)

In SheetLaser.xml You will find the line 

<Flat_Size_F>Abwicklung_F</Flat_Size_F>

where You can define the name for the property containing the area of the flat pattern.

 

Hope this helps.

 

If there are any questions don't hesitate to ask here

Wolfgang
