SHEET METAL ENHANCEMENT: Bump Bend lines in Flat pattern

SHEET METAL ENHANCEMENTS

 

BUMP BEND: Bump bend is small incremental bends in a specific area to achieve a radius. The more hits done the smoother the contour.

 

Where Feature would be shown and created:

Feature would be created in flat pattern view of a part. Option would be grayed out in 3D view but when selecting flat pattern it would be active.

 

Purpose of feature:

When creating a sheet metal part that contains a bend radius (a radius that is large in size compared to standard tooling radius) that cannot be achieved by standard tooling a technique called bump bend at the press brake is used to achieve the radius.

 

Using the bump bend technique you can achieve a course or fine radius depending on the amount of bends are made in this area

 

To help the press brake operator I laser etch (scribe) this area with center lines that go from tangent to tangent lines of the radius in small increments (evenly space). I have to manually add these lines in the .dxf file. The angle to hit each line is an educated guess done at the press brake.

 

The bump bend feature would automatically place these lines in the flat pattern and give the angle to which to hit each bend line to achieve the radius.

 

Real World application:

 

Scenario:

If a sheet metal manufacturer does not own a press brake tooling to achieve a large bend radius.

 

Values to enter to create feature:

When selecting, to execute this feature ,you would get the following options in the dialog box to enter values to create the bump bend lines.

Choose one of the following:

  • Number of hits. The software would take the area and divide by hits and place that many bend lines evenly spaced.

    OR

  • Select course or fine. The software would use programmed algorithms to achieve a course radius or fine radius. Fine would give you more bend lines in this area than course.

 

Profiles to select to create feature:

You would select the area to apply the bump bends. Bend lines would be placed as per the amount you enter or by a process of selecting course or fine.

 

In the drawing of the flat pattern you would get the bend lines and the bend angle for each line needed to achieve the overall radius.

Could you file an ER for what you mention above.
Once you have the ER number, please post here, so we can request to be added to this ER.

@mezcofab you have spent a lot of energy posting some very detailed and well documented sheet metal enhancements -- you do realize that the forums are *not* the place where you submit your enhancements for Solid Edge?

If an ER will be provided i'm happely to support this, this is something I could use.

 

I have something similar

https://community.plm.automation.siemens.com/t5/Solid-Edge-Forum/ER-7851802-Bend-lines-with-angle-in...

 

@uk_dave

Not entirely true, the Solid Edge support in The Netherlands sends us to the forum for every ER we reqeust to generate more people to support the ER.

I will try to get and ER and post it here

@Sander-NL gathering support for an ER on the forums is NOT the same thing as submitting an ER.  You can ONLY submit an ER through your Solid Edge support.

True, but you can also poll the need for the ER first. I think in this case it worked and he is trying to get an ER now and we support it Smiley Very Happy

 

I have a bunch of ER's that multiple company's want, still after 10+ years we are still waiting. So give people a break for not going by the book, the ER system isn't a holy as it only works as far as Siemens wants it to be.

@Sander-NL either you are misreading my intent or having a bad day, not sure which.  I am trying to ensure that @mezcofab understands that submitting your enhancements here on the forums does NOT get those enhancements submitted to Siemens for potential inclusion into the future product.  I have not said anything about not polling for ERs on the forums.  End of story!

 

So give me a break!!!

Hi,

 

I think there are some cases when you can do this, but you have to use Lofted flange command.

 

Here is a video:

 

My note to the ER's. I always enjoy to read ER's here, because I can meet other users' and reseller's challenges. I think that we (users and resellers) can give valuable feedback to each other and developers.

 

I recommend to read this site: Inventor ideastation here everybody can share his ideas what can be useful for developers. This makes a stronger community because everybody can share his thoughts what will make a better software a better Solid Edge (I always "fight" for Solid Edge and SE's users).

 

BR,
