And the material thickness is symboled as uppercase “T”. The distance from the inside face to the neutral axis is called “distance” and it is symbolized by the lowercase “t”. So what is the equation of the k-factor? Here it is: This is a feature of metals (very interesting) So we need to know exactly how much the length increases so that we can produce accurate models. Because the initial length increases after the bend operation. Well, the k-factor is used to calculate the initial length of the flat metal. Because it’s really hard to learn something without knowing what it is used for. Because other angles are a little bit more complex.Īlright first in first, what is the purpose of the k-factor? Why is it so important? These are pretty important questions. So I can learn it )īy the way, I'll be referring to 90-degree angle bend. All you have to do is correct me in the comments or DM.
Keep in mind that I’m a beginner at this and I might be wrong. It’s a quite interesting topic so I just wanna share with you what I’ve learned about this topic. Nowadays I’m learning the fact of k-factor in the sheet metal design and fabrication.
