Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

CASING DESIGN

Objective: To design Sheet Metal casing using Siemens NX Sheetmetal Application.

Introduction: The sheetmetal application provides an environment for the design of sheetmetal parts used in Machinery, Aerospace etc. 

Design Approach: Workflow to design the casing.

1. Sketch the 2D shape of the casing.

2. Construct the Base feature.

3. Add feature such as flanges or bends.

4. Unbend the part and add other features such as dimple, hole, cutuots etc.

5. Create a flat pattern

6. Create a drawing Sheet.

Description: The Design of casing involves various features and tools.

1. Sketch:

This command is used to create the 2D sketch of the casing.

2. Tab:

This command is used to create the base feature by extruding the sketch along a vector by a thickness value or by adding material to existing faces.

3. Normal Cutout:

This command is used to create the cutout to the material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.

4. Bend:

This command is used to bend the material by projecting a sketch on the model perpendicular to the face to bend.

5. Flange:

This command is used to add a flat flange at an angle to the planar face and add a bend between the two.

6. Break Corner:

This command is used to round or chamfer the sharp corners of a tab or flange.

7. Unbend:

This command is used to unbend or flat material to add some more features.

8. Hole:

This command is used to create hole in the part with standard values.

9. Sudio Spline:

This command is used to create spline curve on the face of the part.

10. Move Curve:

This command is used to move or rotate the curve along the certain point.

11. Dimple:

This comman is used to lift the area of the model inside a sketch that simulates as a stamping tool. We can create an indentation in a sheetmetal part using a sketched section as the dimple outline.

12. Bead:

This command is used to lift the material along the contour of a sketch that simulates a stamping tool.

13. Mirror Feature:

This command is uesd to copy a feature and mirror it along a plane.

14. Flat Pattern:

This command creates a flat pattern feature from the formed sheetmetal part.

15. Base View:

Creates the model based view on the drawing sheet.

Conclusion:

1. Sheetmetal casing is created using NX sheetmetal application.

2. Detailed drawing sheet is made and attached.

3. The model is rendered using NX ray traced studio.
