Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket
1. Title of the project
Sheetmetal bracket design using Siemens NX Cad Sheetmetal application.
2. Objective
To understand the procedures used in sheet metal bracket design using Siemens NX CAD software.
3. Introduction
NX for design is an integrated solution that helps you develop innovative new products. Unlike CAD only solutions and closed enterprise solutions delivers the highest integration between development disciplines in an open, collaborative environment. It delivers immense value to enterprises of all sizes It also mergers solid and surface modelling techniques into one powerful tool set. It provides a set of tools within NX environment that allows for simple fast and accurate design of sheet metal parts.
In mechanical engineering a bracket is any intermediate component for fixing one part to another, usually larger, part.This project is a step-by-step approach of sheet metal bracket design using Siemens NX CAD (student edition) software. It is prepared with the self-guiding tutorial by the Skill Lync as a part of my certification course program.
4. Design Methodology
The 3D design of sheet metal bracket design using Siemens NX CAD Student edition software. The methodology followed in the project is as follows:
5. Description
The features used in design are described below.
- Sketch
In NX, create sketch by choosing Sketch in Home toolbar. The screen will display the sketch options. You can choose the Sketch Plane, direction of sketching and type of plane for sketching. Here choose the XC-YC plane and click OK. The sketch plane will appear and the X-Y directions will be marked. This is the basic sketch window.
- Contour flange
It creates main base flange or second flange by extruding sketch in sheet metal application.
To activate command from “Menu => Insert => Bend => Contour Flange”
- Normal Cutout
This command is used to extract volumes from sheet metal by using sheet metal production principles. Cutting faces will be perpendicular to the sheet metal surface.
Click on command on (When sheet metal application activated.) “Home => Feature Group => Normal Cutout”
- Break corner
This tool is used to rounds a sharp corner of a tab or flange.It completely formed with radius and created smooth edges
- Unbend
This command is used to flatten the bend and material adjacent to the bend.
- Bead
This tool is used to lift material along the contour of the sketch that stimulates a stamping tool. Its available from punch group gallery in NX
- Rebend
This command is used to restores an unbend feature to its previous state along with any feature added after the unbend feature.
- Hole
This command is just like to put holes in the sheet metal with respect to measurement
- Flat pattern
This command is used to create a flat pattern feature from the formed sheet metal part

6. Conclusion
This project shows as an example of how NX CAD can be for used to create a bracket design by using various different features as per requirement of the designer.
