Sheet Metal K Factor (What is it and How to Measure it) Solidworks

[@pragathiramesh6854]

One of the best explanations provided

[@md.shahinurrahman747]

The higher value of k-factor physically indicates the hard material, because the neutral axis distance is far away from the middle. And for soft material the neutral axis is close to inner surface of metal regardless of same thickness is considered for two type metraial and same bend angle.

I need a k-factor list that lists a specific number for every conceivable type of metal (and alloy) and thickness for air bending. I use Creo at work, which uses Y-factor as its default, which I know equals K-factor times Pi divided by 2. But I need to know a specific k-factor number for the specific material we're using before I can accurately determine the Y-factor. And we work with all types of materials including 5052, 6061, 2024, 7075, mild and stainless steel sheets and plates. Does anyone know of any such repository of information, or maybe a calculator/spreadsheet that someone has created somewhere?

A nice instructive video on using Sheet Metal K-Factor and other alternatives in Solidworks design. I enjoyed watching. Thank you !

So perfect sir

Youd did not provide leg lengths of the angle so it is hard to cross check, I drew a 2"x2" angle on ACAD, .074 thickness and got a K-factor of .121, so my stretch out would be 4.121 inches?

Many thanks for your comment bro :)

Mashallah! Rahmat for this useful video. Now I understand easily

[@samarsekharreddy]

Very good sir

Hello. Why would one want to change the neutral axis position instead of being dead center on the thickness? has it got something to do with bending angle and radius? Thank for the video, very easily explained :)

[@mohammadzgoul90]

Hey :) The reason why is that if you measure the total length of a sheet before and after bending, they won't be the same. That is the result of the tension and the compression that the sheet wetness during the process of bending. That is why the concept of the k-factor was introduced. basically it is a relation between the neutral axis and the thickness which can be used to approximate the length of the sheet after bending :) There are many factors control this process, the angle, material,the process,etc. So using the k-factor helps us prediction the length of a sheet after pending. Many thanks for your nice comment :)

@@mohammadzgoul90 so the 2 values are supposed to match?

[@cjoy36]

Neutral Axis = Bend Radius + 1/2 * Material Thickness

[@rexnemo]

@@cjoy36 Not quite . The K factor has to be allowed for and this alters depending upon the material .
