This forming tool fails on a sheetmetal. What is the reason for that?

The main rule is that you can not have sharp edges, so you need a fillets (equal to or higher than sheet metal thickness).
I can't see you file because I'm on SW2015 but I'd guess it's a radii problem. The radii of the face that meets the metal needs to be the same or smaller than the thickness of the metal.
Video is attached.
Look at this video.
No sharp corner.
What thickness of sheet metal you're trying to use this tool on? Try with very smaller thickness and this would work.
BTW it is mainly due to shape in my opinion that it is not working.
I wasn't aware that having radii would even work.
What is meant by very smaller? I tried with 1mm and 0.5mm and it did not work.
..you can test this using thicken, you can observe the failures between 0.5mm and 1.9mm
Maha why you don't follow "The rules of stamping" as I see on your form tool you don't have a min radii. If you can't add it you are making a fine tuning tool....and break the neutral fiber of the sheet metal...
Here is a tool that works on 2mm. The main thing I did is to add the boss extrude so I could add a 2.5mm fillet around the top edge. This was necessary in order to get the outside bend radius on the top of the plate. Also added a sketch fillet on two of the guide curves. As has been mentioned, if the tool forms the outside of the material the radius must be at least the material thickness. The portions of the tool that form the inner radii can be sharp but it is a good idea to add a minimal radius since in all probability the tool maker would add something so the tool will hold up.
Having some technical difficulties at the moment.. Will get the .SLDFTP file attached shortly..
All is well..
I don't have a example on English but, as you can see on bottom left you could obtain some cracks on that sharp edges (material don't flow correctly) and the bottom right is a smoth definition of product.
Min Radii=thickness of sheetmetal is considerated a basic rule...
Yup yup....that's it buddy...Handbook of Die Design
Both are excellent handbooks

LOL, I have the blue one at home! I have had it for a lot of years.
I don't buyed a new one, but to make typical works, this handbook still working.....LMAO
