Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
CASING DESIGN USING NX
OBJECTIVE: - Learning sheetmetal module of NX CAD with the help of designing a Casing Bracket.
INTORDUCTION: - Sheetmetal involves work piece with high ratio of surface area to thickness. Sheetmetal thickness is less than 6mm.Unigraphics CAD software highly preferable for sheetmetal designing due to its user friendly interface of modules.
In NX CAD sheetmetal module have many command for designing sheetmetal components.
- Tab & Flanges
- Corners – closed corner, three bend corner & break corner
- Dimple punch
- Drawn cut-out etc.
DESIGN METHODOLOGY AND APPROACH:-
DESCRIPTION: - During the modelling of Casing bracket used many sheetmetal command which are descriptions below:
- TAB: - Creates a base of the sheet metal by using a sketch.
- FLANGE: - Ads flange on an edge and create a bend between two walls. The flange can only be made on a straight edge.
- NORMAL CUT-OUT: - Extracts volumes from sheet metal by using sheet metal production principles. Cutting faces will be perpendicular to the sheet metal surface.
- BEND: - Bends sheetmetal model through a line.
- BREAK CORNERS: - Break corners use for remove sharp corners and convert into in radius.
- UNBEND: - Flattens sheet model through selected bends.
- HOLE: - Siemens NX has a command that users could create or drill standard sized holes with it.
- DIMPLE: - The Dimple command adds a dimple to a flat sheet by deforming it.
- BEAD: - It lifts material along the contour of a sketch that simulates a stamping tool, it is used for giving strength to the sheet metal.
- REBEND: - Rebends, unbended feature of the sheet metal model. It uses after the “Unbend” command if needed.
- DRAFTING: - Drafting is use for prepare 2D CAD drawing which help the manufacturer to produce physical component.

CONCLUSION: - After completing this project I have learned about NX interface and some basic setting and sheetmetal module, command for prepare sheetmetal CAD model.
