Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

CASING_ DESING

sketch a rectangle at 60mm and 50mm dimension

make a surface at 1mm thickness using tab command

make a another sketch on the 50mm side at make a rectangle of 5mm and 30mm dimension

cut the suface by using sketch 3 and normal cut

make 2 line parallel to the 60mm sides at offsets upto 10mm

bent the outer side of surface to top by usng sketch 5 and bend command

apply flange on the 4 edges at 5mm length , the the 2 edges inside and another 2 edges ouside

sharpe egdes of all corners can be remove at break corner at imm radius

then unbent the all surface in to single plane

make sketch on the base plane , create a given sketch at 5mm ditsance

then create a spline by using 16 points and move the spline at 45 deg by using move spine

create a dimple by using the spline sketch at 1mm depth

make a hole at the 4 wings of surface by using simple hole

make circle at the 4 corners of base surface at 8mm distance

create bead by using all the circles sketches at1mm inside direction

make all surface in orginal position by using rebend command

flat pattern commad used to make the pattern

then select the flat pattern from the model views

make a drawing sheet at A4 size , then place the base view at ratio of 2:1

save the part file as casing_design
