Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

OBJECTIVE: To design an advanced casing using the sheet metal application in Siemens NX.

Introduction

Sheet Metal Design is a vast domain in the design of any sheet metal industry, it is used in many sectors including the aeronautics & automotive sectors, in this sheet metal casing design we will look at the design approach using NX (CAD) SOFTWARE through various design, images, explanation, and images.

Design Methodology

• Select a new file in NX cad.
• Create Tab with Reference Sketch.
• Create advanced flanges on the edges of bends created in the previous step.
• Bending operation is done on side of the tab behind the cutout.
• on the tab created as a sketch to perform normal cut-out operation.
• Unbend the Sheetmetal by using unbend command.
• Add the holes required by using the Hole command.
• Sketch is created on the Surface of the tab to perform dimple operation.
• Studio Spline option is selected to create a spline curve.
• Rebend the Sheetmetal By using Rebend command.
• Beads also created with reference to holes where placed at required points Dimple operation with reference to Spline curve.
• Rotated Spline curve to 45 degrees.
• final product was achieved as per the inputs.
• Final Touch up was given in Drafting Sheet with a suitable Scale.

DESCRIPTION:

Sketch:- It’s a basic command to draw 2d models.

Tab:- A command to add parameters/ thickness to a Sketch

Bend:- It’s an operation to bend the tab at a particular position with reference

Flange:- It’s an operation to extend a sheet metal to one of the edges of a tab

UNBEND:- It’s a command used to flatten the created 3d model taking one face as a stationary face.

HOLE:- It’s a command used to create different types of holes like tapping and normal drilling, on the Surface of a Sheet metal.

DIMPLE:- It is a projection command of a particular shape with reference to a sketch with a certain depth.

BEAD:- It is also the type of projection to deform the shape at a certain point with reference to the sketch and also gives strength to the material.

REBEND:- This command is used to re-bend the already flattened sheet metal.
