Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II
DESIGN A SHEETMETAL BRACKET BY USING SIEMENS NX-CAD
OBJECTIVE - Design a Sheetmetal bracket from drawing using NX-Cad.
INTRODUCTION
Sheet Metal
Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal.
There are six major types of sheet metal material, each with its own unique advantages:
1. Alloy steel.
2. Stainless steel.
3. Carbon steel.
4. Tool steel.
5. Galvanized steel.
6. Aluminium.
Sheet metal is used in car and truck bodies, airplane fuselages and wings, medical tables, roofs for buildings (architecture), and many other applications. Sheets of iron and other materials with high magnetic permeability, also known as laminated steel cores, find applications in transformers and electrical machinery.
In this project, I designed a Bracket of Sheetmetal using Siemens NX-Cad software.
DESIGN METHODLOGY
In this project, we use various Sheetmetal operations or features like, Contour flange, Advance flange, hole, Normal cut-off, Break corner, gusset etc to design a Bracket of Sheetmetal.

DESCRIPTION OF FEATURES USED TO DESIGN THE BRACKET
Sketch To create a different shape using sketch tool like line, spline, rectangle, circle, arc etc and provide dimensions and constraints.
Contour flange Creating a base feature by extruding alone a vector or create a flange by sweeping a sketch along edge or chain of edges.
Advance Flange Add flange along edge with some bend at any angle or reference face.
Normal Cutout This feature cut material by projecting the sketch onto the model.
Break Corner To create chamfers or smooth corner of the Tab and Flange.
Unbend This feature flattens the bend and material adjacent to the bend.
Gusset This feature add dart or gusset at bend to increase the stiffness of the model.
Rebend Restore the unbend feature to its previous bend feature along with any feature added after the unbend feature.
Hole To create a hole on the solid bodies with options of countersunk, counterbored, thread.
Flat Pattern Create a Flat pattern feature from the formed Sheetmetal part.
Draft To Convert a 3D model to 2D drawing
