Sheet metal flange - Distance to bend line

[hshorst]

Hi all,

I'm doing a lot of sheet metal work for a customer and they would like their bend lines at even distances from the edge.  I can do this by using the fold option, but in most cases the flange command is easier/faster.  Unfortunately with the flange command I have no way of specifying the distance to the bend line.  The only way I've found is to manually adjust the height of the flange to account for the K-factor.

If I could set the height datum to bend line in the flange command this would be really useful.

Anyone else found a better way to do this?

Thanks,

Steve

Using a flange, it'll always come down to the K-factor, since a flange is calculated based on how it should be when it's finished

Fold, however, is based on the flat pattern, and you ask inventor to tell you how it looks based on that flat pattern with that K-factor.

Why do they care more about the flat pattern bend line dimensions vs final as formed dimensions?

Seems silly.. The final dimensions should be whats important and whatever the bend line distances are is just what they need to be to achieve the proper formed dimensions..

If the don't care about the final formed dimensions then adjust the flange length.. Thats the only real option..

Exactly what I was also thinking 🙂

Shops that I worked with were only intrested in the drawing of the final product for quality check and used the flat DXF (WITH bendlines) for production.

I guess they are an old school shop.  They set their fences on the press brake manually and it's a lot easier for the guys on the shop floor to remember and type in round numbers.
