CHAPTER 1

INTRODUCTION

NX is one of the world’s most advanced and tightly integrated CAD/CAM/CAE product development solutions. Spanning the entire range of product development, NX delivers immense value to enterprises of all sizes. It simplifies complex product designs, thus speeding up the process of introducing products to the market.

NX formerly known as "UNIGRAPHICS" is an advanced high end CAD/CAM/CAE, which has been owned since 2007 by Siemens PLM Software. It is used among other tasks for Design, Engineering analysis, Manufacturing.

• OBJECTIVES

• To design metal bracket using NX-Cad sheet metal applications.
• To familiar about the usage of tools while designing a metal bracket.

FEATURES

• Sketch:

The sketch is the fundamental base element for any feature in the design of any sheet metal component. The very first step is to create sketch which is then used to create tab or the base feature.

Figure 3.1: sketch.

• Counter flange:

The counter flange is an additional face created automatically from any edge of the existing sheet metal component. It is additional material connected to any face or edge which is bent from the respective face or edge.

Figure 3.2: Counter Flange.

• Normal cutout:

it is used to create a cut portion or a gap on the required sketch.

Figure 3.3: Normal cutout.

• Break corner:

Break corner feature breaks the sharp edge in the corner and make it round or adds chamfer. It prevents the fracture breaking of the sharp corners.

Figure 3.4: Break corner.

• Unbend:

Unbend is the very powerful and useful tool in the Siemens NX. It allows all the bend made by various feature to the unbend state at once.

Figure 3.5: Unbend.

• Re bend:

All feature added after the unbend feature are added in the unbend state itself. After the addition of sketches and additional features are completed, the sheet metal components has to be re bend to the required position.

Figure 3.6: Re bend.

• Advanced flange:

Advanced Flange adds flange along the edge using the reference face or bend angle. The edge and reference face can be curved. Flange Properties namely Length, angle, length reference and inset type are defined along with bend parameters, end limits and relief.

Figure 3.7: Advanced flange.

• Hole:

Hole feature in the sheet metal workbench is just like in the model workbench. It can be created simple, counter bore, counter sink or tapered holes.

• Gusset:

Gusset requires that it must have at least one bend in the part in which working on. The key points are to help to snap the gusset to specific point along with the bend.

Figure 3.9: Gusset.

• Flat pattern:

Flat pattern is the representation of the entire sheet metal component in the 2D form of the flat sheet metal with all the additional feature in the form of lines or edges. It removes the possible errors such as interference or collision with in the same component.

Figure 3.9: Flat pattern.

• Drafting:

After the design is complete, the execution or the manufacturing of the component requires a technical drawing of the component with the provided scale and with accuracy.
