Sheet Metal Bend Tables

[bwallace]

I work for a sheet metal manufacturing company. 95% of the products we make are made out of mostly sheet metal parts. As a standard Autodesk Inventor calculates precise bend allowances, but in my case this is not necessary. As a standard we use round numbers such as 1/16" bend allowance for a 90 degree bend using 18 GA S/S. Does anyone have any input or pointers on how to go about setting this up?

Instead of using Bend Tables you could set up your kfactor as neutral and avoid Bend Allowance calculation altogehter.

In addition to JD's suggestion, you could use the new custom equation
capabilities of IV2010 to create just what you've described. If you take a
look at the image that I've attached, it's now directly supported for you to
enter explicit bend allowance values for a variety of variables. While the
custom equation unfolding method does much more than this, building
equalities with a static value is completely legitimate.

I am getting the attached error when trying to save a sheet metal unfold style to the style library in IV2010. The sheet metal unfold style uses a custom equation for every bending radius except 0.25 for which the bend allowance is a static 0.558. I have set up the bounding conditions to handle this but am not able to save this to the style library. Any suggestions?

This message shows as there is an indirection or reference parameter in the style, which is not supported to save in style library. When you remove or change this parameter to value, it should work fine.

Thanks,

I am not sure what reference parameter the error message is referring to.
Screenshot of unfold style is attached. All required values appear to be filled in.
I believe that it has something to do with the rho = 0.25 bounding condition.

[Yijiang.Cai]

That can be reproducible on R2010 based on your description in the image when "=" is used in bounding condition. And it is logged as #1234627 in our tracking system.

Thanks for your post!
