Bending angle is 90.
Catia sheet metal k factor.
Mathematically k factor is a ratio of position of neutral axis and sheet thickness.
You can use this k factor calculator to calculate k factor using reverse engineering method.
After bending the sheet insert the inner radius and flanges a and b.
In this tutorial you will le.
You can also use our flat pattern calculator for blank size calculation.

The line where the transition from compression to stretching occurs is called the neutral axis.
The k factor in sheet metal working is the ratio of the neutral axis to the material thickness.
Sheet metal depends on certain parameters 1 thickness 2 bend radius 3 bend angle.
To calculate the bend allowance the k factor and the derived coefficient called the y factor insert the thickness and initial length of the sheet into the cells on the left.
K factor is a constant used to calculate the sheetmetal flat length.
L ᴫ 2 r y t θ 90.
Our design engineers typically use a factor of 0 4 for our air formed press brake parts.
The k factors mentioned are to suit our own press and tools of course.
Definition of the k factor.

Catia sheet metal tutorial for beginners.
Best way to calculate k factor in sheet metal is by reverse engineering.
Value of the k factor depends on material bend radius sheet thickness and machines used.
When you bend sheet metal the neutral axis shifts toward the inside surface of the bend.
The k factor is the ratio of the neutral axis location t to the material thickness mt.
We produce a lot of sheet metal work using invento and use 0 2732 for below 3mm sheet and 0 3365 for 3mm and above using ilogic we automatically set the k factor depending on the thk of material so we don t forget to adjust it each time.
Value of k factor is always less than 0 5.
K t t why the k factor cannot exceed 0 5.
To figure this out the reason why the k factor can t exceed 0 5 you first need to know what the k factor is.
The k factor is the ratio of the neutral layer position thickness t of the sheet metal to the overall thickness of the sheet metal material t i e.
