SHEET METAL - Sheet metal is
simply metal formed into thin and flatpieces. It is one of the
fundamentalforms used in metalworking, and can becutand bent into a
variety of differentshapes.

Thicknesses can vary significantly,although extremely thin
thicknesses are
considered foilorleaf, and pieces thickerthan 6 mm (0.25 in) are
considered plate.
The thickness of the sheet metal is calledits gauge. The gauge
of sheet metal
ranges from 30 gauge to about 8 gauge.The larger the gauge
number, the thinnerthe metal

Three methods-
Directly start with New part-sheet metal
Start the part and then convert it tosheet metal. (Go to
application/sheetmetal/select driving surface)
Go to assembly > insert > create > sheetmetal

Angle bend- An angle bend creates abend with a specified radius
and angle .
Roll bend- A roll bend creates a bendwith a specified radius ,
but the resultingangle is determined by the radius andamount of
material to bend .

When a sheet metal is developed orbent, the material on the
outside of the
neutral bend plane stretches whilethe material on the inside of
the neutralbend plane compresses . This results indeveloped length
.

L = ( /2 * R + y * T )theta/90
L= Developed length
k= /T y=( /2)*k R = Inside radius
T = Material thickness
Theta = Bend angle
Y- factors and k factors are part constantsdefined by the
location of the sheet metalmaterials neutral bend line which is
largelybased on hardness the material .
