Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

BOX ASSEMBLY

make a sketch on bottom plane at the rectangle of 200m and 150mm dimensions

create a base sheet by using tab commant at 1mm thickness

make sheets at 2 sides of base sheet at 200mm lenth and 10mm raidus of cuvature

make another flange in the 150mm side at 70mm length for two sides 200mm flange

joining the corners by using closed corners command at two ends

make the smaller flange at at the end of 70mm sheet , at the length is 0.001999 and 0mm bend radius

then creat another flanges at 6.5mm length and 0.5mm bend radius , flange is is bended in to outside

create a hem flange in the open condition , at the 0.503mm radius and 5mm length for two sides

make the hem flange for accurate to adjust the bend radius

mirror all the body at the y-z is the refference plane

combine all the sheet by using unite command

create a sketch 16 on the side sheet at 10mm radius

dimple apply on the sketch 16 at 2mm depth and outside direction

then mirror the dimple on the opposite surface by using mirror feature command

create another sketch (20) on the base sauface

then dimple apply on the sketch 20 in inside direction

apply the unbend and rebend command on the sheets

make bead on the corner of base plane at circular cross section and depth and radius is 2mm

mirror the bead on the remaing corners by using mirror feature

create hem flange on the opne faces of sheet metal in the closed type and 2mm lenth

create a datum plane from the bottom surface upto 203mm length

make a sketch oon the new plane as given dimension

make surface into bottom by using tab at 1mm thickness

then apply on the flange in the top sheet as refference of hem flage at 3mm length

create a sketch on the flanges side at rectangel of 20and 55mm dimension

apply tab command to create 1mm thickness sheet and remove the bottom side corner at 10mm radius

make flange on the end of now maked sheet at 4mm length and 40deg angle

similarly make another flange on the end of flange sheet

create a hem flange on the above maked flange at 5mm length and 325 deg angle

unbend the flanges and make sketches on surface as given dimension

cut the flanges at the refference of sketch 46 , then unbend the flanges

mirror the flange creation into opposite side using mirror geometry

create sketch on the top sheet at the side of flanges creation, then make a sheet at 1m thickness

remove the edges of now makes sheet at 100m radius by using break corner command

make flanges on on the outer edges of top sheet at 13mm length and 39ddeg angle

then apply hem flange at 5mm radius and 325deg angle

unbend the flanges and make sketches as refference

cut the extraa portions by using sketch 56

then rebend the flanges
