Catia sheet metal k factor.

From this video will we start catia v5 generative sheet metal design tutorials series. Value of the k factor depends on material bend radius sheet thickness and machines used. I had a question on k factors for our 3 d modeling software. 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. Cad tools use k factor to calculate sheet metal blank size. Catia an acronym of computer aided three dimensional interactive application in english usually pronounced multi platform computer aided design cad computer aided manufacturing cam. In this tutorial you will le.

L ᴫ 2 r y t θ 90. Catia sheet metal tutorial for beginners. Sheet metal depends on certain parameters 1 thickness 2 bend radius 3 bend angle. When you bend sheet metal the neutral axis shifts toward the inside surface of the bend.

Bending angle is 90. You can also use our flat pattern calculator for blank size calculation. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. Mathematically k factor is a ratio of position of neutral axis and sheet thickness.

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. You can use this k factor calculator to calculate k factor using reverse engineering method. The line where the transition from compression to stretching occurs is called the neutral axis. After bending the sheet insert the inner radius and flanges a and b.

K t t why the k factor cannot exceed 0 5. 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. Best way to calculate k factor in sheet metal is by reverse engineering. K factor is a constant used to calculate the sheetmetal flat length.

The k factors mentioned are to suit our own press and tools of course. Definition of the k factor. The k factor is the ratio of the neutral axis location t to the material thickness mt.
