Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II
DESIGNING METAL BRACKET FROM THE 2D DRAWING USING NX CAD
OBJECTIVE:
The main objective of this project is to design a metal bracket as per the requirement.
INTRODUCTION:
Sheet Metal Fabrication is the process of forming parts from a metal sheet by punching, cutting, stamping, and bending.
3D CAD files are converted into machine code, which controls a machine to precisely cut and form the sheets into the final part.
Sheet metal parts are known for their durability, which makes them great for end use applications. Parts used for low volume prototypes, and high volume production runs are most cost-effective due to large initial setup and material costs.
Sheet metal Brackets are manufactured by conducting stamping or die casting operation. These can be used for many application for mounting of any products like antennas to TV, projectors or street lights, etc.
DESIGN METHODOLOGY:
DESCRIPTION:
Contour Flange: It is created by extending the sketch on its respective axis with the thickness as required from the base.
Normal Cutout: This feature is used to remove the material from the sheet metal material. A profile is first drawn using the sketch feature and the material will be removed inside the sketched profile.
Break Corner: It is used to make the corners blend with some self dimensioned radius in order to make corners smooth.
Unbend: This feature is used to convert all the angled flanges into flat sheet metal by selecting the base face along which all the other flanges need to be straightened.
Rebend: It is used for bending corners of the unbend body.
Advanced flange: Advanced flanges can be made on the edges and reference faces by adding flange along an edge using a bend angle or a reference face which can be straight or curved.
Hole: A Hole feature is used to create holes on the model.
Gusset: Creates a stiffening gusset on the part.
Flat Pattern: It is used to represent the whole component in 2D form. This flat pattern also shows entire features with dimensions.
Drafting: Drafting is creating a technical drawing into a sheet, communicating about the dimensions and view of components. The draft helps the manufacturing and production department to know about the product design in a 2D format.
