Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

TITLE - Advanced Sheet Metal Design Using NX Cad

OBJECTIVE –

• Understanding Advanced sheet metal design.
• Modelling parts with sheet metal workbench of SiemensNX.
• Create uniform thickness sheet metal parts using basic features such as tabs, flanges, cut-outs, etc.

INTRODUCTION –

The sheet metal application provides an environment for the design of sheet metal parts used in Machinery, Automotive, Aerospace, Marines, etc. Sheet metal is a metal such as aluminium, brass, titanium, nickel, tin, and copper processed into thin flat pieces like foils, leaves, and plates.

Sheet metals are a valuable asset to industries and low volume production. Many industries are adopting the concept of Design For Manufacturability, or more commonly known as DFM. In sheet metal design industries, DFM helps avoid technical errors in the design process to improve the manufacturing lead times based on the sheet metal thickness chart and preceding calculations.

DESIGN METHODOLOGY / APPROACH –

DESIGN DESCRIPTION –

CASING DESIGN MODEL 01

SETTING PARAMETERS –

SKETCH –

BASE FEATURE – TAB

Creates a base feature by extruding a sketch along a vector by a thickness value or adds material on a planer face. Additional planar sections can be added to generate bends as part of the base feature. adds a flat flange at an angle to a planar face and adds a bend between the two.

CUTOUT FEATURE –

Cuts material by projecting a sketch on to the model and then cutting perpendicular to the faces intersected by the projection.

BEND FEATURE –

Modifies the model by bending material on one side of a sketch line, adding a bend between the two sides.

FLANGE FEATURE –

Adds a flat flange at an angle to a planar face and adds a bend between the two.

BREAK_CORNER –

Rounds or chamfers a sharp corner of a TAB or FLANGE.

UNBEND – ( to add more sheet metal features )

Flattens a bend and the material adjacent to the bends.

ADDITIONAL FEATURE HOLE –

ADDITIONAL FEATURE DIMPLE –

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

ADDITIONAL FEATURE BEAD –

Lifts material along a contour of a sketch that simulates a stamping tool.

MIRROR FEATURE –

Copies a feature and mirrors it across a plane.

REBEND – (To get the final shape)

Restores an unbend feature to its previous bent state along with any features added after the unbend feature.

FINAL MODEL –

FLAT PATTERN –

Creates a flat pattern feature from the formed sheet metal part.
