Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

Casing Design

Objective: To create a sheet metal casing design with dimples and beads.

Introduction: Dimples and beads help in reducing the weight of the sheet metal. It also helps in increasing the strength of the material. These kinds of techniques are used in fields like aerospace, race motor vehicles and even in kitchen ware.

Design methodology:

Description: In this section we will see the features used in the design of this sheet metal.

1. Tab: This feature is used to create a sheet metal of given thickness from a sketch.
2. Normal cut-out: Using normalcut-out we can make a cut-out in the sheet metal in the shape of any sketch.
3. Bend: This feature is available under more button of the bend group. It is used to bend the sheet metal along the chosen curve.
4. Flange: This feature is available in the bend group. It helps in creating flanges of a given dimension and also a given angle along the selected edge of the sheet metal.
5. Break corner: This feature is used to make the sharp edges of sheet metal blunt. It is available in the corner group.
6. Unbend: Click on unbend button from the form group.
7. Hole: This feature is available under more button of the feature group. It is used to make holes in the sheet metal.
8. Studio-spline: Using studio spline we can form a spline by specifying the 16 poles.
9. Move curve: The curve formed can be rotated by using move-curve option. The origin is selected as the stationary center.
10. Dimple: Dimple is a feature available in the punch group. To make a dimple one has to select the sketch and also give depth as input.
11. Bead: This feature is also available in the punch group. To make a bead one has to select the sketch as the bead shape and also give depth as input.
12. Mirror Feature: This feature is available under the more button in the feature group. One as to give the plane about which the mirror should happen and also the feature to be mirrored.
13. Re bend: While re bending the sheet metal one should make sure that it is done in the reverse order of unbending process.

Conclusion: Hence by using the above features and following the above process we can make the required sheet metal.
