DESIGNING A SHEET METAL CASING

OBJECTIVE :

The objective of the project is to design a sheet metal casing using nx cad sheet metal application also the drawing sheet should be created for the casing

INTRODUCTION :

Sheet metal is metal formed by an industrial process into thin, flat pieces. sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into various shapes

CASING: it is a part that can be an outer sheet for various components or products which has various flanges, dimples, cutouts, and other feature

DESIGN METHODOLOGY

DESCRIPTION

Design requirements :

sheet size = 60mm x 50mm x 1mm
bend angle = 90 degree
dimple depth = 1mm
screw clerance hole = Normal H13 , M2
break corner = 1mm
bead depth = 1
flange length = 1mm

FEATURE USED FOR CREATING THE CASING :

TAB: Creates a base feature by extruding a sketch along a vector by thickness value or adds material to a planer face. An additional planer section can be added to generate bends as part of the feature.
NORMAL CUTOUT: cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection
BEND: modifies the model by bending material on one side of the sketch line, adding a bend between the two sides.
FLANGE: adds a flat flange at an angle to a planer face and adds a bend between the two
BREAK CORNER: Rounds or chamfer a sharp corner of Tab or flange
UNBEND: Flattens a bend and the material adjacent to bend
MIRROR: copies a feature or body and mirrors it across a selected plane
HOLE: adds a hole to one or multiple positions on a solid body
DIMPLE : it simulates a stamping tool by lifting an area of the model
BEAD: it stimulates a stamping tool by lifting material along a contour of sketch
REBEND: restores an unbend feature to its previous state
FLAT PATTERN: creates a flat pattern from the formed sheet metal part
