Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket

BRACKET

OBJECTIVE

To design a bracket from a given 2D drawing sheet.

METHODOLOGY

DESCRIPTION

Step 1. Sketch and contour flange

Feature Used: Contour flange

A sketch is sketched on the xz-plane front view and contour flanged for a width of 200 mm 3mm thickness and a bend radius of 7 mm.

Step 2. Sketch and normal cut

Features Used: Normal cut out

Another sketch is sketched on xy-plane and normal cut for a depth of 35mm

Step 3. Break the corners

Feature Used: Break corner

The bottom edges are broken for a radius of 25 mm, middle edge for 30 mm and top edge for

60 mm.

Step 4. Unbend and sketch

Feature Used: Unbend & bead

The bracket is unbent and sketched for the bead feature

Step 5. Re-bend

Feature Used: Re-bend & holes

The model is re-bent and three holes of 20 mm diameter are added to it.
