DESIGN A BOX ASSEMBLY USING NX CAD(Sheet Metal)

DESIGN A BOX ASSEMBLY USING NX CAD(Sheet Metal):

OBJECTIVE:

• The aim of this project is to design the Box Assembly using NX CAD (Sheet Metal Application).

INTRODUCTION:

• NX, formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned by Siemens PLM Software.
• NX sheet metal design software incorporates material and process information in sheet metal-specific modeling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corner and edge treatments, patterns and other formable features. You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.

DESIGN METHODOLOGY:

• 

DESCRIPTION:

• NX CAD (Sheet Metal):
  • Open NX CAD sheet metal model.
    
• SET PREFERENCES:
  • Sets parameters and characterstics for Sheet Metal Commands.
• TAB:
  • Creates a base feature by extruding a sketch along a vector by a thickness value, or adds material to a planar face.
  • Additional planar selections can be added to generate bends as part of the base feature.
• FLANGE:
  • Adds a flat flange at an angle to a planar face and adds a bend between the two.
• CLOSED CORNER:
  • Closes a corner where two adjacent flanges ture meet by extending the bends and flanges.
• HEM FLANGE:
  • Modifies the model by folding the edge of a sheet metal flange over onto itself for the purpose of safe handling or to increase edge stiffness.
• MIRROR BODY:
  • Copies a body and mirrors it across a plane.
• UNITE:
  • Combines the volume of two or more solid bodies into a single body.
• DIMPLE:
  • Lifts an area of the model inside a sketch that simulates a stamping tool.
• BEAD:
  • Lifts material along the contour of a sketch that simulates a stamping tool.
• MIRROR FEATURE:
  • Copies a feature and mirrors it across a plane.
• UNBEND:
  • Flattens a bend and the material adjacent to the bend.
• NORMAL CUTOUT:
  • Cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.

• 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.
• DRAFTING:
  • Starts the Drafting application, which provides tools to create and maintain drawings of the design model.
    • New Sheet: Creates a new drawing sheet
    • Base View: Creates a model based view on the drawing sheet.

ORIENTATION VIEWS:

• Front View:
