Catia Sheet Metal K Factor

K factor is a constant used to calculate the sheetmetal flat length.

Catia sheet metal k factor.

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. Our design engineers typically use a factor of 0 4 for our air formed press brake parts. Value of the k factor depends on material bend radius sheet thickness and machines used. 1 introduction sheet metal introduction 2 primary walls and secondary walls 3 sheetmetal parameters 4 k factor and y factor 5 various sheet metal tools 6 creating sheet metal components.

Bending angle is 90. L ᴫ 2 r y t θ 90. Sheet metal depends on certain parameters 1 thickness 2 bend radius 3 bend angle. After bending the sheet insert the inner radius and flanges a and b.

I had a question on k factors for our 3 d modeling software. 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. Cad tools use k factor to calculate sheet metal blank size. When metal is bent the top section is going to undergo compression and the bottom section will be stretched.

When you bend sheet metal the neutral axis shifts toward the inside surface of the bend. The k factors mentioned are to suit our own press and tools of course. The line where the transition from compression to stretching occurs is called the neutral axis. Catia sheet metal tutorial for beginners.

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. The k factor is the ratio of the neutral axis location t to the material thickness mt. 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. Best way to calculate k factor in sheet metal is by reverse engineering. Value of k factor is always less than 0 5. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness.

From this video will we start catia v5 generative sheet metal design tutorials series. 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. In this tutorial you will le.
