Hello,
I use often the module of sheetmetal, and according to bend tables I assume that the default bend tables, gives acceptable results.
Did you try to use the TABLE2 of Pro/SHEETMATET for bending values ?
Below I want to remind you the bend tables of pro/e :
Pro/SHEETMETAL provides the following three bend tables for your use:
Table Name Material Y-Factor K-Factor
TABLE1 Soft Brass and Copper 0.55 0.35
TABLE2 Hard Brass and CopperSoft Steel Aluminum 0.64 0.41
TABLE3 Hard CopperBronzeCold Rolled SteelSpring Steel 0.71 0.45
