K Factor Sheet Metal - Let's break down this calculation with an example: Web k = (180×ba) / (π×θ×t) − (rᵢ/t) k = (180×15) / (π×60×10) − (10/10) k = 0.432. In fact, it varies according. It is also known as bend allowance and serves to calculate the sheet metal layout. The bend allowance is the length of the neutral axis between the bend lines, or in other words, the arc length of the bend.
