Advanced Sheet Metal Design Using NX Cad Challenge 1 Casing Design

Title of the Project: Advanced Sheet Metal Design Using NX Cad Challenge 1 Casing Design

Objective: To design a Casing with the help of NX advance sheet metal.

Introduction:

NX Sheet Metal provides a set of tools within the NX design environment that allows for simple and fast design of sheet metal parts, dependent on their material and manufacturing process. NX sheet metal design software incorporates material and process information in sheet metal-specific modelling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corner and edge treatments, patterns and other formable features.

We can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.

NX Sheet Metal-specific features such as flanges, tabs, jogs, corner conditions, and drawn cutouts & many more along with productivity enhancements such as – automatic bend reliefs.

So, in this project I am going to design a Casing by using sheet metal tools and commands.

Design methodology / approach

DESIGN METHADOLOGY :

Select new file in NX cad

Saved with Suitable Name

Select the XY Plane to draw the Sketch

Tab is created with Reference Sketch

Advanced flanges on the edges of bends create in previous step

Bending operation done on side of the tab behind the cut out

on the tab created as sketch to perform normal cut out operation

Unbend the Sheetmetal by using unbend command

Added the holes where ever required by using Hole command

Sketch is created on the Surface of tab to perform dimple operation

Studio Spline option is selected to create 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 degree

final product was achieved as per the inputs

Final Touch up was given in Drafting Sheet with suitable Scale

DESCRIPTION:

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

Tab :- A command to add parameters of an Sketch

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

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

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

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

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

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

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

Description

The important tools which used during designing of Casing are as follow:

• TAB: Creates a base feature by extruding a sketch along a vector by a thickness value or adds a material to a plane face.

• Cutout: Cuts the model perpendicular to the sketch.

• Bend: Modifies the model by bending material on one side of a sketch line adding a bend between the two sides

• Flange: Adds a flange to an angle to a planar face and adds a bend between the two

Break Corner: Rounds a sharp corner

• Unbend: Flattens a bend

• Hole: Hole command use to create a hole on one or more solid bodies in a part or assembly with option for counterbored, countersunk, and threaded.

• Studio Spline: Creates spline through defined points. We can change positions of points or drag points while the command has been activated.

• Move Curve: We can move our sketch entities according to selected reference and reference points, which makes moving sketch objects is very effective.

• Dimple: Lifts an area of the model inside a sketch that simulates stamping a tool.

• Bead: Lifts a material along a counter of sketch that simulates stamping a tool.

• Mirror Feature: Used to mirror w.r.t plane or reference.

• Rebend: Restores a bend

• Flat Pattern: Creates flat pattern feature from the formed sheet metal part.

• Base View: Used to create a model view on the sheet.

Conclusion

While designing a casing I have understand and learnt different tools such as Tab, Flange, Dimple, Bending, unbending and many more in sheet metal of NX.
