Design of Odd Shaped Enclosure

ADVANCED SHEET METAL DESIGN USING NX CAD IN “SHEETMETAL PART FOR ODD SHAPES”.

OBJECTIVE:

Main objective of the project is to create a workflow for Enclosures with odd shapes or angles design. And also to create a Flat pattern feature for drafting and manufacturing purposes.

SOFTWARE USED: NX 12.0

• To design the Sheetmetal casing in NX 12.0 version using some basic feature to create them.
• NX Software is a flexible and powerful integrated solution that helps you deliver the products faster and efficiently.
• NX Cad software is widely used automotive, aerospace, thermal power station. It is used to product developing and manufacturing at all stages of the life cycle.

INTRODUCTION:

1.Let’s get started how NX Cad software performing in Sheetmetal application. Sheetmetal fabrication is the process of forming parts from a metal sheet by punching, cutting, stamping, and bending.

2.3D files are converted to machine codes to control the machine movement to create the desired shape of the component.

3.There are different types of material are used in this fabrication process, such as ALUMINIUM, BRASS, COPPER, STEEL, TIN.

4.Sheet metal parts are known for their durability, which makes them great for durability, which makes them great for end use applications.

5.Parts are used for low volume prototypes high volume production runs are most cost-effective due to large initial setup and material costs.

6.Because parts are formed from a single sheet of metal, designs must maintain a uniform thickness.

7.Be sure to follow the design requirements and tolerances to ensure parts fall closer to design intent and cutting sheets of metal.

DESIGN METHOLOGY: (SHEETMETAL PART FOR ODD SHAPES)

DESCRIPTION:

In this project we will creating the workflow for Sheetmetal part for odd shapes. There was one new feature is used to create the solid body to Sheetmetal part. Let’s start our project.

SKETCH:

Sketch is used for creating the model by specify shape and dimensions.

SKETCH FEATURE EXPLANATION:

• In this model we want to create a extrude, so that why we are creating the sketch option.
• Draw a sketch and specify the dimensions you want.

EXTRUDE:

Normally we can use extrude option in cad software widely. It is used to create the solid body in specify sketch and also to define the direction of the extrude feature.

EXTRUDE FEATURE EXPLANATION:

• Extrude option is available in Features menu and go to click this you will see the extrude feature option.
• Then, select previous sketch, specify the vector direction, to give distance(200mm) and click ok.
• Now you are creating the solid body in XZ Plane.

SHEET METAL FROM BODY:

Builds a Sheetmetal model that takes its shape from a collection of Planar faces.

SHEET METAL FROM BODY FEATURE EXPLANATION:

• First you select the Web faces and the edges.
• Then, it is automatically created the suitable edges. And give the thickness value of 3mm.
• It is created the Solid body to Sheetmetal Body from using the Sheetmetal from solid Body feature.

FLANGE:

This tool is used to create the bend structure of the edges of the Sheetmetal.

FLANGE FEATURE EXPLANATION:

• First select the which edges you want to create to bend. In this model you just click the one of the edges.
• Then specify the dimensions, Length(20mm), Angle(90), Length reference(inside), Inset(Material inside) and bend radius(3mm).

JOG:

Modifies the model by lifting the material on one side of a sketch line, adding a flange between the two edges.

JOG FEATURE EXPLANATION:

• First draw a sketch line and select the targeted faces to create the jog feature. And specify the direction of feature created.
• Give the dimension of Height (20mm), Height reference(inside), Inset (Material inside).

UNBEND:

Unbend feature is used to unbend the bended region in NX Sheetmetal workbench.

UNBEND FEATURE EXPLANATION:

• Unbend feature is to create the flattens the ODD shapes Sheetmetal.
• If the Unbend feature we are using it will Flattens the Sheetmetal and adjacent to the bend.

BEAD:

Bead feature is used to lift material along a contour of the sketch that stimulates the stamping tool.

BEAD FEATURE EXPLANATION:

• Bead operation is just lifting the material along contour of the sketch.
• First just create a sketch which places you want to perform bead operation. And then select sketch to create bead operation.
• Then specify the Cross section (Circular), Depth and Radius(3mm), End condition (Formed shape), Minimum tool clearance(5mm).

HOLE:

Adds a hole to one or more solid bodies in a part or assembly with options for counterbored, countersunk, and threaded.

HOLE FEATURE EXPLANATION:

• First select the which type of holes you want to select (General hole).
• To specify the position of hole in UNBENDED Sheetmetal top.
• Select the direction (Normal to face), Form (Simple), Diameter(10mm), Depth limit (Through body) and BOOLEN operation select (Subtract).

REBEND:

REBEND option is used to unbend feature to its previous bent state, along with any feature added after the unbend feature.

REBEND FEATURE EXPLANATION:

• It is just Restores an unbend features to its previous bend state.
• And it is including to the any feature added to after the unbend feature.

ODD SHAPES BODY VIEWS:

1.FRONT VIEW:

2.TOP VIEW:

3.RIGHT SIDE VIEW:

4.ISOMETRIC VIEW :

DRAFTING:

We can create the 2D Drawing sheet from Sheetmetal part for odd shapes model in NX Cad software.

DRAWING SHEET:

• Drawing sheet is used to represent the Sheetmetal model in 2D view(A4) help of NX cad platform.
• It is show the which feature you are using in this Sheetmetal part for odd shapes model in NX Cad software.

DETAILED VIEW:

• Detailed view is nothing but it is just Show the recommended view from the model in single sheet(A4).
• You will see the detail view in A4 size sheet top, right, front, isometric views in detailed view for Sheetmetal part for odd shapes.

CONCLUSION:

• In this project we are creating the Sheetmetal part for odd shapes design in NX Cad Siemens 12.0 version platform.
• So, in this project we will learn the how to change the solid body to Sheetmetal part in simple manner.
• Designing the Sheetmetal part in NX cad software, it is user friendly interface for creating 3D model in NX Cad software.
