Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

DESIGN A BOX ASSEMBELY USING NX CAD(SHEET METAL):

OBJECTIVE:

1. The aim of this project is to design the box assembly using NX CAD.

INTRODUCTION:

1.NX, formerly know as unigraphics in an advanced high-end CAD/CAM/CAE, which has been owned by siemens plm software.

2. NX sheet metal design software incorporates material and process information in sheet metal-specific modeling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corners and edge treatments, patterns and other formable features. you can also quicly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.

DESIGN METHODOLOGY:

DESCRIPTION:

1. NX CAD

Open NX CAD sheet metal model.

2.SET PREFERENCES:

Sets parameters and characterstics for sheet metal commands.

3.TAB:

Creates a base features by extruding a sketch along a vector by a tickness value, or adds material to a palaner face.

Additional planar selection can be added to generate bends as part of the base feature.

4.FLANGE:

Adds a flat flange at an angle to a planar face and adds a bend between the two.

5.CLOSED CORNER:

Closes a corner where two adjacent flanges meet by extending the bends and flanges.

6.HEM FLANGE:

Modifies the model by folding the edge of a sheet metal flange over into itself for the purpose of safe handling or to increase edge stiffness.

7.MIRROR BODY:

Copies a body and mirror it across a plane.

8.UNIT:

Combines the volume of two or more solid bodies into a single body.

9.DIMPLE:

Lifts an area of the model inside a sketch that simulates a stamping tool.

10.BEAD:

Lifts material along the contour of a sketch that simulation a stamping tool.

11.MIRROR FEATURE:

Copies a feature and mirror it across a plane.

12.UNBEND:

Flatten a bend and the material adjacent to the bend

13.NORMAL CUTOUT:

Cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.

14.REBEND:

Restores an unbend feature to its previous bent state, along with any features added after the unbend feature.

15.FLAT PATTERN:

Creates a flat pattern feature from the formed sheet metal

16.DRAFTING:

Starts the drafting application, which provides tools to create and maintain drawings of the design model.

new sheet: Creates a new drawing sheet

Base View: Creates a model based view on the drawing sheet.

ORIENTATION VIEWS:

DRAFTING:

CONCLUSION:

Thus the is box is designed and drafted by using NX CAD.
