Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
ODD SHAPED ENCLOSURE USING NX CAD IN SHEET METAL APPLICTION
Objcetive:
The main objective of this project is to create the odd shaped enclosure and its flat pattern in NX cad Sheet Metal Application.
Introduction:
This project is to create the enclosure, by creating the solid model and wraping the sheet metal over the solid surface. Then we need to add the features in the wrapped sheet metal.To add more features like Dimple, Louver, Beads then the sheet metal has to be unbend. Finally flat pattern has to be created to check the manufacturing fesability of that product.
Design Methodology:
Description:
Step 1: Creating the solid body
The sketch for the solid body has to be created. Then the sketch is to be extruded using Extrude command which is avaliable in the modelling workbench.
Step 2: Extrusion of the skectch
The sketch is extruded upto 200mm. Thus the solid body is ready to wrap up with the sheet metal over the surface. By wraping the sheet metal we can get the solid shape profile in the sheet metal.
Step 3: Wrap the solid body
The solid body is now wrapped with the sheet metal using the command Sheet metal from the solid. This command helps in building a sheet metal model that takes its shape from a collection of plannar surface.
Step 4: Adding Features
The features like flange is added at the edge of the sheet metal.
Jog Feature is added by creating a sketch on the face of the sheet metal. Then the jog command is used with the required height to make the feature.
Step 5: Unbend
The sheet metal is unbend using unbend command. This is done to add a features like dimple, bead in the bending region.
Step 6: Creating Bead
For creating the Bead, sketch profile is created on the face of the sheet metal and the bead command is used with the requires depth value. Then the feature is mirrored using the mirror feature command.
Step 7: Hole creation
The hole is created, using hole feature command. Here the position of the hle is created and the diameter is mentioned as per the requirement.
Step 8: Rebend
After creating all the required features, then the model is to be Rebend. This enable us to check the manufacturability of the product without any interference while bending.
Step 9: Flat pattern
This option is to create the flat pattern feature from the formed sheet metal part. This finally gives the whole sheet metal part with the added feature which helps us in the manufacturing process.
