Catia Sheet Metal K Factor

The line where the transition from compression to stretching occurs is called the neutral axis.

Catia sheet metal k factor.

Definition of the k factor. Catia an acronym of computer aided three dimensional interactive application in english usually pronounced multi platform computer aided design cad computer aided manufacturing cam. When you bend sheet metal the neutral axis shifts toward the inside surface of the bend. You can also use our flat pattern calculator for blank size calculation.

Value of k factor is always less than 0 5. Sheet metal depends on certain parameters 1 thickness 2 bend radius 3 bend angle. Mathematically k factor is a ratio of position of neutral axis and sheet thickness. Best way to calculate k factor in sheet metal is by reverse engineering.

Catia sheet metal tutorial for beginners. 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. Bending angle is 90. 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.

The k factors mentioned are to suit our own press and tools of course. From this video will we start catia v5 generative sheet metal design tutorials series. After bending the sheet insert the inner radius and flanges a and b. You can use this k factor calculator to calculate k factor using reverse engineering method.

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. 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. Value of the k factor depends on material bend radius sheet thickness and machines used.

In this tutorial you will le. The k factor is the ratio of the neutral axis location t to the material thickness mt. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness. L ᴫ 2 r y t θ 90.

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