Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
Title of the project:Advanced Sheet Metal Design Using NX CAD Challenge 2Box Assembly.
objective: To design a Box assembly using Siemens NX sheet metal application.
introduction
1. SIEMENS NX: NX formerly knovwn as 'unigraphics" is an advanced high-end CAD CAM/CAE, which has been owned since 2007 by Siemens PLM Software.
2. SHEET METAL DESIGN:NX sheet metal Design provides the design professional with a complete set of tools to efficiently create and manage sheet metal parts
based on the knowledge of material properties and manufacturing processes. NX sheet metal design tools incorporate material and bending information enabling the model too represent both the formed component and flattened blank shapes.
Design Methodology:
STEP1 :Base was created using Tab command.
STEP2 :Walls were created using Flange command.
STEP3 :Corners were closed using Close corner feature.
STEP4 :Used Flange and Hem flange feature to lock the walls.
STEP5:Whole box was created using Mirror feature command.
STEP6:Unite the two bodies.
STEP7:Create a profile on the side walls.
STEP8:Created a Dimple using the previous profile.
STEP9 :Using the mirror feature copied the dimple on the opposite side.
STEP 10 Created a emboss on the base using dimple feature.
STEPI1:Unbend Re bend the box.
STEPI2 Four beads were created on the base using Bead and Mirror feature
STEP13:Created hem flange on the top of walls on all four sides.
STEPI4 :Box cover was created using tab command.
STEPI5:FIange was created on one side of the box cover.
STEP 16:1Tab was used to create base for the hinge.
STEP 17 :Using flange, Hem flange normal cut out hinge was creation the side wall.
STEP18:Using mirror feature another hinge was created.
STEPI9:Similarly another hinge was created on the box cover
Description
SKETCH It is a basic of any design.
TAB it is used to create base feature of a sheet metal.
Flange - it is used to create a extended part of a sheet metal.
UNBEND This feature is used unbend the sheet metal taking any one face as a stationary face.
REBEND used to rebend the sheet metal.
DIMPLE Used to create pitch up or pitch down surface.
BEAD-Used for giving strength to the sheet metal.
Hem - Used to fold the edges of the tabs & flanges.
Close Corner It is used to close the corners.
Normal Cut out - It is used to make a normal cavity in a sheet metal
