Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
Design of Casing Using NX CAD
Title: Advance Sheet metal Casing Design
Aim/Objective:
- To design a sheet metal model of casing using NX CAD
- Provide some flanges, bending, Holes, Dimple & Bead etc…
- Convert into the Flat pattern & Drafting
Introduction: Casing May Refer to an enclosing shell, tube or surrounding material. It may also refer as a container or cover that goes around something to hold it together or protect it. This type of casing generally used in the Automobile engine application Like Caterpillar V12 Engine
- Function:
The engine case protects an engine from outside debris and pollutants.
- Benefits:
In case of engine failure, an engine casing will protect the driver of a vehicle by keeping broken debris inside the casing.
- Types
Types of engines with engine casings include motorcycle engines, jet engines, diesel truck engines, automobile engines and steam engines.
Process: Following are the different Step for designing casing below:-

Features Used for design:
Description of Features:
1). Tab: This feature is used to create the base using sketch by providing appropriate thickness.
2). Normal Cutout: This feature is used to cut the portion of tab by creating sketch on tab.
3). Bend: This feature is used to create a bend using sketch curve on tab portion
4). Flanges: Flanges are used to extent the edges of sheet at certain angle. It is work as bend feature
5). Break Corner: This feature work as a blend/fillet used to create round edges of sharp corner of sheet.
6). Unbend: This feature are used when we have to create some sketch on flat surface.
7). Holes: Holes are create for the purpose of mounting the bolt.
8). Dimple: Dimple are provided on the tab for providing the strength of the sheet metal
9). Studio Spline: This feature is used create a spline of any sharp curve by taking all bi poles point.
10). Move Curve: It is used to move the curve at an appropriate angle.
11). Bead: This feature is used to provide better strength to the sheet metal. It is just like an embossing
12). Rebend: This feature is used whenever all the sketch drawn on the flat section are conformed & ready to be manufactured.
13). Flat Pattern: This feature is provide the flat view of part including all the dimension.
14). Bend Table: In this table all the dimensions of the part are mention in the tabular form
15). Drafting: It is a kind of drawing which include all views.

Conclusion: Gained Knowledge about Sheet metal & its Application. After geting the NX Knowlege i am able to desing a Casing using different tool like Tab, Flanges, Bend, Dimple, Bead etc..
