Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
SHEET METAL CASING DESIGN USING NX CAD
INTRODUCTION
The purpose of this project is to mainly understand the different tools and features used in NX cad software for modelling a sheet metal casing and to get a clear knowledge and understanding of the features and tools in NX cad.
OBJECTIVE
The main objective is to understand and learn all the features and tools used in the NX cad software.
METHODOLOGY
The first step is to understand the design of the casing which we are going to model.
After that we will sketch the model or the part in the NX cad software.
Then using the appropriate feature and tool from the sheet metal we model the part.
After completing we will draft the model.
DESCRIPTION
Casing-
- MODELLING
Tools/Features used-
- Sketch
- Tab
- Normal cutout
- Bend
- Flange
- Break corner
- Unbend
- Hole
- Dimple
- Bead
- Mirror
- Re bend
- Flat pattern
In the first step we sketch the casing on a plane. Then we use the tab feature. The tab feature allows us to extend a sketch according to the thickness value given in the preferences.
Then using the cutout option we cut a small portion from the base. We sketch a line for bending then use the bend option to bend the sheet. Flange option is used to create flanges at the corner where we bent the sheet.
Break corner is used when we want to give a fillet or a chamfer on the edges. Then we use the unbend option to unbend all the bends given. We then make a hole on the four corners using the hole feature. We then sketch on the flat plane to create a dimple and bead. Dimple feature is used to lift an area which stimulates as a stamping tool and the bead option also does the same just the difference is that it lifts the material along the contour. Then we use mirror to mirror the feature at the four corners.
Using the re bend option we re bend all the bends that we previously unbend.
Flat pattern feature is used to just show the sheet metal without any bends.
2. DRAFTING
The draft is nothing but a two dimensional drawing of the model which we created for better understanding.
CONCLUSION
We were able to model the casing with sheet metal and got to learn about the various features used in NX cad.
