Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket
TITLE OF THE PROJECT
To design a Sheet Metal Bracket using sheet metal application of NX CAD.
OBJECTIVE
The main objective of this project is to design a Bracket using Sheet metal and to learn about the basics, fundamentals and advanced features of NX Sheet metal
To learn all the basics about Bracket Designing using sheet metal
INTRODUCTION
In this project, we are going to create a bracket design using NX Sheet metal application and after that we have created the 2D drawing sheet of the model using top view front, right view and right section view.
To create bracket design in NX Sheet metal, first of all we have to create the desired sketch of given dimension and after that the sketch is converted to the given sheet and designed as per the guidelines using various features and tools such as Contour Flange, Corner Break Bead etc.
The various features used in Bracket designing are:
- Sketch
- Contour Flange
- Normal Cutout
- Break Corner
- Unbend
- Bead
- Rebend
- Hole
DESIGN METHODOLOGY AND DESCRIPTION
WORKFLOW
- Create a sketch with proper dimensioning
- Converted to sheet using Contour Flange
- Again, the sketch is created
- The created sketch portion removed using normal cutout
- Unbend the bend edges
- Creating Bead on top surface
- Rebend
- Create Holes
Design methodology and description of feature:
To create the bracket design in NX Sheet metal, first of all a sketch is created in XZ plane with proper dimensioning as per the given pdf and then the sketch is converted int sheet using Contour Flange Feature
CONTOUR FLANGE: This feature is used to create a base feature by extruding a sketch along a given vector and add material by sweeping the sketch along an edge or chain of edges.
After that, again a sketch is created in XY plane that is the top plane and then the area covered by the sketch is removed with the help of normal cutout feature.
NORMAL CUTOUT: This feature is used to remove the material according to the sketch drawn. The area of the sketch is removed using this feature
The next step is to break the corners and round it according to the given radius using break corner feature.
CORNER BREAK: This feature is used to round or chamfer the sharp corner of tab or flange.
After that, the bend edges were converted to straight using the unbend feature.
UNBEND: This feature is used to unbend the bend edges of the sheet.
Then beads are created on top face of the bracket using BEAD feature.
BEAD: This feature lifts the sketch along the contour of the sketch. It is used to provide the strength to the body
The unbend edges were bend again using the rebend feature.
REBEND: This feature is used to bend the unbend edges again.
And finally simple holes were created using the hole feature.
