Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

REPORT ON CASING DESIGN USING NX CAD

OBJECTIVES:

• Design the sheet metal using NX CAD.
• Gain knowledege How to Utilise the different NX features and their applications.

INTRODUCTION:

NX formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE. The NX softwere supports product developing and manufacturing at all stages of the life cycle. NX supports modeling of both complex surfaces and solid models. NX sheet metal provides a set of tools within the NX design of sheet metal parts, dependent on their material and manufacturing process.

DESIGN METHODOLOGY:

MODEL DESIGN DESCRIPTION:

Features used:

SKETCH:

Sketch is a quick and rough drawing and gives a brief account or gereral outline. It allows designers to quickly visualize multiple design concepts.

TAB:

It gives the base features of the model by adding the material to the given sketches as per the required thickness.

BEND:

Bend used to create the model in required direction & angle.

FLANGE:

It is used to create the an additional body from the edge of the existing sheet metal.

BREAK CORNERS:

It creates the smooth rounded edges.

UNBEND:

Bend the model into its previous state.

HOLE:

Hole is used to create the different type of the holes on sheet metals.

DIMPLE:

Dimple used to create the model by lifting selected area inside the sketch for creating the stamping press to the model.

BEAD:

Used to lift the material along selected sketch that stimulates a stamping tools.

MIRROR:

Mirror creates the copy of the body.

FLAT PATTERN:

Used to create a flat pattern from the formed sheet metal.

STEPS USED DURING DESIGN:

• Set the parameters to 1 mm.

• Create the sketch in XY plane.
• Apply Tab application to the sketch with 1mm thickness.

• Draw the rectangular shape sketch on base Tab & Exist the Sketch.
• Use Cutout tool to Create the Rectangular Shape Hole.

• Bend the Model.
• Draw Two Symmetrical lines on the Tab & Exist the Sketch.
• Then apply Bending Application.

• Add flange.

• Use Break corner & break all the corners with 1mm.
• Unbend the model.
• Create the sketch on Tab as a reference of hole center Ppoint.
• Use the Hole Option to create the hole with referece of Point.

• Create sketch in XY Plane.
• Apply Dimple with depth 1mm.

• Draw circle on XY Plane.
• Apply Bead Tool.
• Mirror the Beads.

• Again Bend the Model.

• Hide all the sketches.
• show the solid bodies.
