Catia Sheet Metal K Factor

Bending angle is 90.

Catia sheet metal k factor.

In this tutorial you will le. Sheet metal depends on certain parameters 1 thickness 2 bend radius 3 bend angle. 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. Cad tools use k factor to calculate sheet metal blank size.

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. K t t why the k factor cannot exceed 0 5. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. The k factor is the ratio of the neutral axis location t to the material thickness mt.

When you bend sheet metal the neutral axis shifts toward the inside surface of the bend. L ᴫ 2 r y t θ 90. You can also use our flat pattern calculator for blank size calculation. 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.

K factor is a constant used to calculate the sheetmetal flat length. From this video will we start catia v5 generative sheet metal design tutorials series. 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.

Value of k factor is always less than 0 5. 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. Mathematically k factor is a ratio of position of neutral axis and sheet thickness. Catia sheet metal tutorial for beginners.

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. Definition of the k factor. Our design engineers typically use a factor of 0 4 for our air formed press brake parts.

Best way to calculate k factor in sheet metal is by reverse engineering. After bending the sheet insert the inner radius and flanges a and b. Value of the k factor depends on material bend radius sheet thickness and machines used.
