60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them.
Bend angle represents the angle to which sheet metal has bend here it is 90 degree.
Generate optimized cutting patterns based on the available stock sheets by nesting the required parts.
R is inner bend radius.
Where ba is bend allowance.
You only have to insert interior angle flange lengths k factor inside radius and material thickness.
Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1.
This is used to calculate the back stop location when working off of a flat pattern.
Ba bend angle π 180 r k factor t eqn 1.
When designing parts for laser cutting one should not make holes smaller than the thickness of the material.

In the settings box enter the length of the steel or wood that you will be cutting the required lengths from.
A lot of steel is not exactly the length that it is sold as.
The formula for calculating sheet metal bending allowance is please refer to the above picture.
We are going to review three bending scenarios with three different bending angles.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
