how to give length and width in BOM of the flat part coming from the bended & rolled sheetmetal?

Dear All,

 

My concern is that my company has specific bend table program for this ,and its tough for me to calculate the length and width of the unbended part ,example I have sheet with 3 mm rolled to 100 MM dia with 100 mm length but so whenever I go with the formula of PI()*D for width ,it deviate from the what creo give.

Is there any method to join the L & WIDTH in d relation from unbended family part.

 

Thanks,

Manish

We are using Creo 2 and we create a revolved feature in sheet metal for cylinders like your first image.  We change the bend allowance to our company standard for rolled parts, then we create a flat pattern using the flat pattern preview icon and create a family table instance of the flat pattern.  This gives you a flat pattern id which we then use to get the length and width of the flat in our bill of materials.

Can you show a picture of what your shape looks like?

The sheetmetal package is designed for bent parts, not rolled ones. We used to do 1" flats on each end of a rolled cylinder, but these were 30" to 60" in diameter.

After we create the flat pattern and the Flat Pattern ID is shown in the tree we go to TOOLS, then RELATIONS and the width and length lines are at the bottom as shown in the second image in my previous reply, but they are commented out with /* at the beginning and */ at the end of each line.  We delete those and add the id number from the tree after the underscore and then select OK.
