Catia Sheet Metal K Factor

When metal is bent the top section is going to undergo compression and the bottom section will be stretched.

Catia sheet metal k factor.

Our design engineers typically use a factor of 0 4 for our air formed press brake parts. 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. 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. The k factor is the ratio of the neutral axis location t to the material thickness mt.

Sheet metal depends on certain parameters 1 thickness 2 bend radius 3 bend angle. 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. Definition of the k factor. Bending angle is 90.

From this video will we start catia v5 generative sheet metal design tutorials series. The k factors mentioned are to suit our own press and tools of course. K t t why the k factor cannot exceed 0 5. You can use this k factor calculator to calculate k factor using reverse engineering method.

Catia an acronym of computer aided three dimensional interactive application in english usually pronounced multi platform computer aided design cad computer aided manufacturing cam. The line where the transition from compression to stretching occurs is called the neutral axis. When you bend sheet metal the neutral axis shifts toward the inside surface of the bend. L ᴫ 2 r y t θ 90.

Value of k factor is always less than 0 5. Cad tools use k factor to calculate sheet metal blank size. In this tutorial you will le. Catia sheet metal tutorial for beginners.

Value of the k factor depends on material bend radius sheet thickness and machines used. K factor is a constant used to calculate the sheetmetal flat length. 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. Mathematically k factor is a ratio of position of neutral axis and sheet thickness.

The k factor in sheet metal working is the ratio of the neutral axis to the material thickness. You can also use our flat pattern calculator for blank size calculation. I had a question on k factors for our 3 d modeling software.
