K-Factor
K-Factor is a ratio that represents the location of the neutral sheet
with respect to the thickness of the sheet metal part.
When you select K-Factor as the bend allowance, you can specify a K-Factor
bend table. The SolidWorks application also comes with a K-Factor bend
table in Microsoft Excel format. This is located in <installation_directory>\lang\English\Sheetmetal
Bend Tables\kfactor base bend table.xls.
You can specify different values
for the K-Factor in different configurations.
You can also apply a material-based default
K-Factor by using a Sheet
Metal Gauge table.
Bend allowance with a K-Factor is calculated
as follows:
BA=P(R
+ KT) A/180
where:
|
BA = bend allowance
R = inside bend radius
K = K-Factor, which is t / T
T = material thickness
t = distance from inside face to neutral sheet
A = bend angle in degrees (the angle through
which the material is bent) |
