Catia sheet metal k factor.

K t t why the k factor cannot exceed 0 5. Bending angle is 90. Definition of the k factor. 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.

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 k factor in sheet metal working is the ratio of the neutral axis to the material thickness. I had a question on k factors for our 3 d modeling software. 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. The line where the transition from compression to stretching occurs is called the neutral axis. 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. K factor is a constant used to calculate the sheetmetal flat length.

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. You can use this k factor calculator to calculate k factor using reverse engineering method. Catia sheet metal tutorial for beginners. After bending the sheet insert the inner radius and flanges a and b.

When metal is bent the top section is going to undergo compression and the bottom section will be stretched. You can also use our flat pattern calculator for blank size calculation. Mathematically k factor is a ratio of position of neutral axis and sheet thickness. Value of k factor is always less than 0 5.

Cad tools use k factor to calculate sheet metal blank size. 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. The k factors mentioned are to suit our own press and tools of course.

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. From this video will we start catia v5 generative sheet metal design tutorials series.
