Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

ODD SHAPE ENCLOSURE

OBJECTIVE

To design a sheet metal part for odd shapes following the workflow procedure

METHODOLOGY

DESCRIPTION

Step 1. Creating a solid body

Features Used: Extrude

A sketch of 200 mm length, 100 mm height 60 ° is created and extruded for 200 mm.

Step 2. Wrapping the body with sheet metal

Features Used: Sheet metal from solid

The sheet metal from solid is used to wrap a sheet metal around the extruded solid. All the faces are selected for web faces and their edges for bend edges with a 3mm thickness.

Step 3. Adding features

Features Used: Flange & jog

Flange of 20 mm length and 90° is added to one side and jog flange is added to another side.

Step 4. Unbend to add more features.

Features Used: Unbend, holes & beads

The model is then unbent to add more features like holes and beads. The holes are 10 mm diameter and the beads are of depth 3 mm and 3 mm radius.

Step 5. Re-bend the unbent areas

Features Used: Re-bend

The model is re-bent the same order it was unbent.

Step 6. Create a flat pattern

Features Used: Flat pattern & draft

Creates a flat pattern feature from the formed sheet, It is then drafted for a scale 1:1.
