Forming Tool Problem

Hi All,
I am trying to create a simple 25mm dimple in a sheet metal part 1.6mm
thick. I have modified the forming tool appropriately with 25mm radius
and a 10mm fillet. I get the error:

"counter sink emboss21. The part's thickness may not be compatible
with this form tool. The thickness must be less than the minimum
radius of curvature for the form tool."

I am probably missing something simple here but cannot see it. Can any
body help please?
Thanks in advance.

how deep is the emboss?
where is the fillet, at top or bottom?

i have no issue with a 25dia x 3.2deep x R10 (top) x R3 (bottom) dimple on
1.6 thk material.

 

Hi Kenneth,
Back to basics.......
If I use the default dimple, with no modifications, in SW2007 design
library, and use it to create the dimple on 1.6mm thick material, I
get the same error. I think that I may be missing something very
simple here, but cannot see it. Any ideas?
Thanks,
BM

 

What's maybe confusing to us is your use of the word "dimple" and the
error is for a "counter sink"?

Anyhow, the reason is.... you've matched the base extruded of 50mm x
50mm (Dia 50 or R25) and it errors out,.. so, you'll have to change
the emboss file to >50mm,.. that is, if you change it to Dia 46 (or
R23) you'll see that the default radii (R4) will be laying or riding
on what seems to be 4 corners (the 50mm x 50mm base extrude)?
