Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

BOX ASSEMBLY DESIGN IN NX CAD

Designing of the box assembly with sheet metal using the NX cad

The NX cad software is used to create the models and calculate the product life management PLM. So now we are using the NX cad software to design the accurate and exact cad model of the given product.

Design methodology:-

• Open sheet metal in NX cad.
• Take dimensions of the required model.
• Separate the features (base, flange, dimple, bends and etc)
• Create the base or tab using sketch with given dimensions.
• Create flanges to both sides.
• Create the extra flanges with given parameters.
• Create the closed corners on flanges.
• Now create flanges and hem flanges on both sides of the flanges wit given parameters.
• mirror and unite the mirror bodies
• create dimples with given parameters and mirror them on another side.
• Create circular bead with given parameters and mirror them as per requirements.
• Create he flanges on top of the model
• Create the tab on top and create the flanges.
• Create tabs and break corners then create hem flanges.
• Unbend the tabs and create drawn cutout and rebend them. mirror them.
• Create the same on the top of the model again.
• model is ready

Flange:-

flange is used to extend the edge of the material with required angle and with required length.

Tab:-

tab is normal extrude feature with thickness. It will be used to extrude the closed diagrams and linear faces.

Dimple:-

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

Bead:-

Bead is similar to the dimple. Lifts and of the model along the sketch that simulates a stamping tool.

Bend:-

To bend the sheet metal with some angle we will use the bend feature.

Unbend&rebend:-

Unbend is used after the using of bend feature if we want create more features on the model then we need to unbend the sheetmetal.

Rebend is the feature that used after the unbend of a existing model to create the final model after the features or modelling is completed.

Normal cutout:-

Normal cutout is used to create the hole in flat or normal face with different closed drawings.

Hem flange:-

Hem flange is similar to the flange but with folded edge to give strength to edge.

Mirror:-

Mirror feature is used to mirror the body, feature and sketches to another side with using the planes.

views of the model:-

conclusion:-

The model of the box assembly with sheet metal with nx cad is prepared with some changes in given parameters as per the requirement to model and some adjustments as been made. And model is prepared.
