NX-BOX Assembly

OBJECTIVE:

My Aim in designing a Box is to get introduced to basic assembly modelling using Siemens NX sheet metal application and to learn how various features of NX application can be used for sheet metal design.

INTRODUCTION:

Sheet metal is a metal formed by an industrial process into thin, flat pieces. One of the most fundamental forms used in metalworking and can be cut and bent into a variety of different shapes. It can be seen used in designing automobiles, aircraft bodies, utensils, and beverage cans. It takes a variety of forms: plain flat sheets, embossed, etched, ribbed, corrugated, and perforated.

DESIGN METHODOLOGY:

Sketch – Tab – Design Parameters – Flanges were created – Closed Corners- Hem Flanges were created to create the interlock loop – Body was mirrored to create the extension – United to form the two parts together – Move Curve - Dimple – Beads – Tab to create hinge – Break Corners – Unbend - Normal Cut out – Re bend – mirror body -unbend – break corner- normal cut out – Rebend.

DESCRIPTION:

• Designparameters: Parameters added before sketching your required sheet metal.
• ClosedCorners: to create adjacent bends into a whole part or piece.
• HemFlange: To create an open or closed loop.
• QuickTrim: To alter down specific dimensions.
• MoveCurve: To create a dimension and giving it specific angles to move it around.
• Mirrorbody: To create a copy of the feature or body into a selected plane.
• Unite: To create two specific bodies into one.
• Normalcut out: To make a cut out through your sketched body.
• Bending: To bend your extruded body with the required angle and length.
• Flanges: To create a flange on the required body.
• Breakingcorners: To give smooth cuts on the edges.
• Dimple: to have a formed shape on your body.
• Beads: to create formed shaped with required parameters.
• Re-bend: to re-bend the unbend body.

CONCLUSION:

The following project shows how to design the sheet metal box assembly from scratch.

This Box Assembly design exercise has introduced me to NX sheet metal design application and its various features.
