SHEET METAL CASING DESIGN USING NX CAD

TITLE: SHEET METAL CASING DESIGN USING NX CAD

OBJECTIVE:

To design a sheet metal casing using NX CAD (sheetmetal workbench)

INTRODUCTION:

In this project we are gonna design a sheetmetal casing with NX CAD on sheetmetal workbench. NX is a advanced CAD (computer aided design), CAE (computer aided engineering), CAM (computer aided manufacturing). The software performs in DESIGN (parametric and direct solid/surface modelling), Engineering analysis (static, dynamic, electro-magnetic, thermal, using the finite element method and fluid, using the finite volume method. Manufacturing finished design by using included machining modules.

DESIGN METHODOLOGY:

DESCRIPTION:

1. TAB - It creates a sheet metal of preferred thickness. create a sketch of rectangle and select TAB tool to create a sheet metal.
2. CUTOUT - Cuts out a section of a part with reference to a sketch.
3. BENDING - Creating a reference line for bending action which acts as the bend angle for the sheet metal. select BEND tool after the reference sketch lines and using the lines as reference create bend.
4. FLANGE- Used to create a flange from the stationary part and bends between both and creates and bend flange.
5. BREAK CORNER - Rounds or chamfers sharp corner edges of a flange or tab. select the tool BREAK CORNER and just click the edges to be chamfered.
6. UNBEND - Unbend all the flnages and bends created in a progressive form to repeat in REBEND.
7. HOLE - Under design feature more there is HOLE tool which adds hole to any part with preferred type and specification of holes.
8. DIMPLE - A tool for stamping feature which represents on a curve sketch for reference. It lifts the material through the sketch marking as a stamping feature.
9. BEAD - Another stamping tool features the lifting of material with sketch along the contour.
10. REBEND - Restores the UNBEND feature along with the bend in the reverse progressive manner of the UNBEND with representing the stationary face or tab.
