Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

PROJECT

ADVANCE SHEET METAL DESIGN OF CASING USING SIEMENS NX

OBJECTIVE:

1. To design casing using NX-cad sheet metal applications.

2. To familiar about the usage of all tools while designing the casing

INTRODUCTION:

Nx is one of the worlds most advanced and tightly integrated CAD/CAM/CAE product developnment solutions. spanning the entire range of product development, NX delivers immense value to enterprises of all sizes. it simplifies complex product designs, thus speeding up the process of introducing multiple products to market.

Nx formaly known as unigraphics is an advanced high end CAD/ CAM/ CAE, which has been owned since 2007 by siemens plm software. it is used among other tasks for Design, Engineering analysis, manufacturing.

METHODOLOGY:

DESCRIPTION:

1. Sketch:

The sketch is the fundamental base element for any feature in the design of any sheet metal component. The very first step is to create sketch which is then used to create tab or the base feature.

2. TAB:

The tab is the very first feature in any sheet metal design process. All the other feature of the sheet metal is siemens NX are based on the base feature or tab. A taab is created after sketch is created in any of the plane. The tab is always the parent feature for other feature following it.

3.BEND:

Bend feature is added whereever the bend in the sheet metal required. A sketch is required to create a bend. it can be an open profile and it can be either a straight line or curve.

4.FLANGE:

The flange is an additional face created automatically from any edge of the existing sheet metal component. it is additional material connected to any face or edge which is bent from the respective face or edges.

5.BREAK CORNERS:

Break corner feature breaks the sharp edge in the corner and make it round or adds chamfer. it prevents the fracture breaking of sharp corners.

6.Unbend:

Unbend is the very powerfull and useful tool in the seimens Nx. it allows all the bend made by various feature to the unbend state at once.

7.Hole:

Hole feature in the sheet metal workbench is just like in the model workbench. it can be created simple, counterbore, countersink or tapered holes.

8.DIMPLE:

Dimple in the sheet metal component provides more strength and rigidity to the flat structure of the components. Dimple features is created using the sketch created in any face or any flange in the sheet metal components.

9.BEADS:

Beads are the features added in the sheet metal components in order to increase the stiffness of the component. Beads require a sketch in order to apply the feature. it can be either open or closed profile.

10.RE bend:

All feature added after the unbend feature are added in the unbend state itself. After the addition of sketches and additional features are completed, the sheet metal components has to be re bend to the required position.

11.FLAT PATTERN:

Flat pattern is the representation of the entire sheet metal component in the 2D form of flat sheet metal with all the additional feature in the form of lines or edges. it removes the possible errors such as interference or collision with in the same component.

12.DRAFTING:

After the design is complete, the execution or the manufacturing of the component requires a techinical drawing of the component with the provided scale and with accuracy.

CONCLUSION:

A sheet metal casing was successfully designed in the sheet metal work piece of siemens NX
