SHEET METAL ENHANCEMENTS

 

BREAK OFF TAB:

 

Where Feature would be shown and created:

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

 

Feature would be shown in flat pattern of sheet metal part so that if sheet metal part would be in an assembly the break off tab would not cause interference with other parts.

 

Purpose of feature:

When creating a sheet metal part and the edges are not parallel with the bend line.

 

Real World application:

 

Scenario 1:

If a sheet metal manufacturer does not own a press brake with back gauges that move independently which aid in bending parts that have edges that are not parallel with the bend line then the break off tab would aid in creating a parallel edge.

 

Scenario 2:

Sheet metal manufacturer has a part with round non flat edge to line up on the back gauge of a press brake to make a bend. The break off tab would create this flat edge.

 

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 tab:

  • Break off tab width

  • Distance from bend line

  • Size of tabs

  • Size of cut opening

  • Select if the tab will be placed from:

  • left side of profile (Flush or enter value to offset)

  • right side of profile (Flush or enter value to offset)

  • center of profile

 

Profiles to select to create feature:

You would click on the following profiles to place break off tab:

  • Select profile to place break off tab

  • Select bend line to be parallel to

Hi @mezcofab

 

 

You know that You can add flat areas to the flat pattern?

 

And the geometry could look like Your requested form.

I currently do add this manually to my flat models. I am looking for a way to automate it.

 

We recently picked up a customer that makes suspension parts for UTV (side by sides) that enter races such as King of the Hammers. They have sheet metal based assemblies with many parts that require this feature.

 

An automated feature like this would save me a lot of time.
