solidworks >> Forming Tool Problem

by blue mongoose » Wed, 16 Apr 2008 17:40:55 GMT

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.

BM

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)?

1. Sheet Metal Forming Tools - Surfaces Simulate The Part

Hi Folks,

I have been playing around with sheet metal forming tools and using
surfaces to show a better image of the part feature you will get when
you use a given forming tool.

Essentially, the pallette will generally show you the anti-image of
the part (a view of the punch).  After a bit of playing around I have
come up with a novel way of using surfaces to design your part feature
in the pallette and have the part that forms inherit what was done,
resulting in a forming tool.

In short - design your part feature (with surfaces) in the pallette
part instead of playing the "punch design" game and hoping the part
comes out right when the forming tool is applied.  Derive the forming
tool from the part and then hide the forming tool body (not required
but makes the pallette look nicer).  When you go to use the forming
tool, the "real" part feature will appear and will be easier to
understand.  Since you have driven the forming tool part of the
pallette model from a viable part definition, you are assured a
correct forming tool outcome.

I like this one and thought is was worth sharing.

3. Insert forming tool fails (2005 sp0.0 and 0.1)

I'm trying to insert the louver that comes with Solidworks and when I
drag it over from the Design Library to a simple plate that I've
already added the Sheet-Metal feature to, I get the following error:
"Are you trying to make a derived part?"

If I say Yes, then it starts the derived part process (bad).  If I say
No then it simply opens the louver in it's own window.  At no time do I
get the preview that I recall seeing in 2004.
Anyone know what stupid mistake I'm making here?

5. forming tool orientation sketch

When did they change forming tools? Overall nice job, much simpler, but 
they seem to have blown it big time with the orientation sketch unless 
there is something I'm missing.

The orientation sketch cannot be edited. That in itself is not 
necessarily a problem, but if the footprint of the feature is 
symmetrical but the rest of the feature is not, then the "orientation" 
sketch becomes a "disorientation" sketch. Manually created sketches are 
ignored, it adds the giant "L", but this is not in the orientation sketch.

Fortunately you can edit it after you guess wrong.
