How to define material size for sheet metal bending in Pro/Engineer and UG NX3? 1. Open Sheet metal part (stabilizer_cover.prt)
This tutorial use for determine raw material sheet size for bending part.
In this tutorial I used simple part called stabilizer_cover.prt. This is simple part, so you can create this part quickly by yourself.
OK, lets to starting this tutorial in Pro/E wild fire
2. Click Application at Menu Bar and then choose Sheet metal, pop up menu SMV Convert will appear (this converting part modeling to sheet metal modeling) choose driving srf and determine thickness value (in this tutorial use thickness 0.5 mm), and then press green check list.
3. Now, we on sheet metal environment application with new command for sheet metal. In menu manager click Feature -> Create ->Sheet metal -> Unbend-> Regular -> Done. Select surface as fixed surface, -> Unbend All -> Done. And now you can measure sheet size. Enjoy it…
Now, Let’s Try in Unigraphic NX3
1. Open Sheet metal part (stabilizer cover.prt) then choose click application in menu bar, choose sheet metal -> forming/flattening, Part in Process dialog box appear, Choose OK.
2. In new Environment windows click Tool in menu bar then choose flat Pattern and Flat Pattern Dialog box will appear.
Default selection this dialog box is Unform Sheet Metal Feature, so just pick top surface on your part and Bend Allowance Formula in Flat Pattern Dialog box will active.
3. Click Bend Allowance Formula and Bend Allowance Formula Dialog box appear, choose 1 formula (you can change constant number, as your material reference, i change constant to 0.3183 same with pro/E default setting). Click OK.
4. Click Apply to unform this part. And The Result like below picture.
An the result is 484.637mm x 200mm same with pro/E result.
