Advanced Sheet Metal Design Using NX CAD Challenge 1 Casing Design
Tittle of the Project:- Advanced Sheet Metal Design Using NX CAD Challenge_1_Casing_Design
Objective:- To design a Sheet Matel casing by using Siemens NX12 Sheet metal application.
Introduction:-
1. SIEMENS NX: NX formely known 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 materia properties and manufacturing processes. NX sheet metal design tools incorporate material and bending information,enabling the model to represent both the formed component and flattend blank shapes.
Design Methodology
STEP1 : create a rectangular tab of dimensipn 60*50 and thickness of 1mm.
STEP2 : create a rectangular cutout of dimension 5*40 using Normal Cutout.
STEP3 : two horizontal lines were drawn at distance of 10mm from the upper and the lower edges of the tab respectively.
STEP4 : bent the sheet using those two lines as a reference.
STEP5 : Flange of lenght 5mm were added at 90 deg at the extreme position of the bend portion.
STEP6 : Corners of the flanges were brocken with a radius of 1mm using break corner feature.
STEP7 : Faces were unbent using unbent feature.
STEP8 : 4 Screw clearance holes of M2 size were added to the new flanges.
STEP9 : The specified sketch was drawn on the plan, a dimple was created taking that sketch as a reference
STEP10 : 4 beads were created using the feature Bead.
STEP11 : Rebend the sheet using Rebend feature.
STEP12 : A flat pattern view was added using feature flat pattern.
STEP13 : Drafting has been done.
STEP14 : END
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 to 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.

CONCLUSION
By this challenge I had learned how to use basic feature like Tabs, flange,break corner,dimple,unbend,rebend etc.
