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.

Dear Ben ,

Please check the image attached . first is of rolled part from which I need the flat part length 2nd image .

similarly 3rd and 4rth for the bended sheetmetal part .

I want to give d-relation of L and width to flat part lengths.

Thanks Bunney,

Can you give some idea of feature id's where this description "W=SMT_FLAT_PATTERN_WIDTH:FID_7386" you come to know .

if you have any link to find out that what can we do by writing what in relation?

But really thanks for this reply.

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.

Hi Gary,

Its a old post, though if you are still active on this community, would you help me out further more on this topic. We are using Creo-5 . the issue is with the same topic that i need the Length, Width & Thickness in my BOM when i extract it.

Since i Am new to this relations and parameters. can you kindly help me create a relation.

i followed your screen shot and gave the relations. but its giving the following error. And how do i relate this with the parameters??

It would very nice of you if you elaborate furthermore

kindly help i would be grateful to you
