sheet metal, three flange corner
sheet metal, three flange corner
(OP)
I would like to create a non-welded metal sheet box which have third flange instead of close corner connection.
Sure, there is no problem to make it but finally SW doesn't allow me to connect three flange together! I have to make a possible small clearance at connection. I have to create a flatten part view to translate it further to our punching machine. The flattened part should have hole at place of flanges begins and miter of two flange together under angular 45deg which begins from the center of hole.
I have tried to make box "back to front" - creating a flattened part and trying to bend necessary sides, but the bend lines cross over each over!
I have SW2004.
Thank you in advance for suggestions!

RE: sheet metal, three flange corner
RE: sheet metal, three flange corner
material thickness is 1mm
bending radius is 1mm
hole diameter is 2mm (punching tool diameter, 2xThickness)
k-factor is 0.5
Thank you!

Try the hole at something like 2.00002mm dia or similar until you get a difference that is large enough to get past the interference checking. You can always adjust you precision on the hole dimension in the drawing to remove the offending value in the insignificant digits.
