Sheet Metal Part Properties
Sheet Metal Part Properties define the type of material and bend allowances. You can define
these properties by clicking
File > Preferences > Sheet Metal.
On the
Sheet Metal Prefer-
ences
dialog, select
Parameter Entry > Value Entry
and type-in values in the
Material
thickness
,
Bend radius
,
Relief depth
,
Relief width
boxes.
Next, type-in a value in
Neutral Factor Value
box. The
Neutral Factor
is the ratio that
represents the location of neutral sheet measured from the inside face with respect to the
thickness of the sheet metal part. The Neutral Factor defines the bend allowance of the sheet
metal part. The standard formula that calculates the bend allowance is given below.
A = Bend Allowance
R = Bend Radius
K = Neutral Factor = t/T
T = Material Thickness
t= Distance from inside face to the neutral sheet
A = Bend Angle
