Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
Objective
Write a detailed report on Sheet Metal Component with good explanation on Sheet Metal modelling tools applied throughout the modelling. Also attach the Final model Images (Min. 4 images) of Sheet Metal Odd Shaped Enclosure.
Introduction
Sheet Metal Fabrication is the process of forming parts from a metal sheet by punching, cutting, stamping, and bending. Parts are formed from a single sheet of metal, designs must maintain a uniform thickness. Parts used for low volume prototypes, and high volume production runs are most cost-effective due to large initial setup and material costs. Sheet metal parts are known for their durability, which makes them great for end use applications (e.g. chassis). They are used in different machineries, automobiles, and aerospace sectors.
Sheet metal components can be created in NX under sheet metal module. From a sketch it can create both simple and complex components using different features such as Tab, Bend, Flange, Hem, Jog, Bead, Dimple, Cutout, Louver, Punch, Unbend etc. Then it is converted in flat pattern for manufacturing purpose. In this project, An Odd shaped Enclosure is created in NX using few of the previously mentioned operations.
Design Methodology
Description
- Extrude- Creates feature by extruding section along a vector.
- Sheet Metal from Solid- Builds a sheet metal model that takes its sgape from a collection of planer faces. Select all the faces except bottom one and top four edges tw create sheet metal model as per image.
- Flange- Adds a flat flange at an angle to a planer face and adds a bend between the two.
- Jog- Modifies the model by lifting material on one side of a sketch line, adding a flange between the two sides.
- Unbend- Flattens a bend and the material adjacent to the bend.
- Bead- Lifts material along the contour of a sketch that simulates a stamping tool
- Hole- Adds a hole to one or more solid bodies in a part or assembly with options for counterbored, countersunk, and threaded
- Rebend- Restores an unbend feature to its previous bent state, along with any features added after the unbend feature.
- Flat Pattern- Creates a flat pattern feature from the formed sheet metal part.
