Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
BOX ASSEMBLY DESIGN USING NX CAD
OBJECTIVE: To design a Box Assembly using NX CAD tool.
INTRODUCTION: The learning of steps & features involved in designing a Box Assembly using an NX CAD tool. :
DESCRIPTION:
STEP 1: Start NX CAD. Then set the world parameters as per requirements. Menu-->Preferences-->Sheet metal
STEP 2: Design a base sketch for box and make a base with Tab option TAB: A tab is employed to create a base of the model along the planar face with respective thicknesses. A sketch with single or multiple closed profiles will be formed as a base
STEP 3: Use the Flange choice to form the side bodies of the box. FLANGE: The flange feature creates a flat bent profile at an angle to a planar face.
STEP 4: Then apply a closed corner at the adjacent bends for either side. CORNER: The corner feature helps to shut a corner where two adjacent bends meet.
STEP 5: After closing the corner, use Hem Flange to make a 'U' profile which self-lock s the sheet after bending. HEM FLANGE: Hem Flange is employed to switch the model by folding the sting of the flat solid flange over onto itself.
STEP 6: Now mirror the body to create a replicate of the present body. MIRROR: Mirror feature mirrors the chosen face or body across the chosen planes or line.
STEP 7: Now unite the 2 bodies (Existing body & Mirrored Body). UNITE: Unite features accustomed unite the chosen bodies into one body.
STEP 8: Now create a sketch and make a dimple on the front & bottom side of the box and mirror it on the backside. DIMPLE: Dimple is one amongst the punching processes which is employed to boost a district of the model perpendicular to the face where contour sketch is drawn
STEP 9:After that, create a sketch for creating beads. Then select the bead option with a circular cross-section and provides proper radius and depth and mirror it to form it four beads at the underside BEADS: Beads are wont to lift a cloth along the contour of the sketch.
STEP 10: Then use hem flange at top edges to form a 'U' shaped corners which neglect the sharp edges and build a smooth & safer edge. HEM FLANGE: Hem Flange is employed to switch the model by folding the sting of the flat solid flange over onto itself. LID:
STEP 11: Create a datum plane at resp distance. Then design a base sketch for the lid and build a base with Tab option.
STEP 12: Use Flange to form the bends within the lid which seats on the perimeters of the box. (3) HINGE:
STEP 13: Using the proper side face of the box as a reference, create a base for the hinge employing a Tab option.
STEP 14: Use break corner option on the hinge base to avoid the sharp edge.
STEP 15: Then using the flange and hem flange, create a circular profile with the dia where the hinge rod gets inserted to lock.
STEP 16: After creating flange, unbend the profile with the employment of the Unbend option. UNBEND: This feature is solely wont to flatten the bent profile.
STEP 17: Create a sketch that should be cut out from the profile with Normal Cutout. NORMAL CUTOUT: A cutout profile is employed to get rid of the fabric from the bottom.
STEP 18: Then rebend the model & mirror it to induce the most effective view of the model with the replication of the present body. REBEND: Rebend is employed to revive the model to its bent state.
STEP 19: Repeat the identical steps for mating hinge by taking the highest side of the lid as a reference for creating a tab.
Since the unite command was not working, I did the whole design without the unite command.
