Mathematically k factor value is equal to the ratio of position of the neutral axis and sheet thickness. In this article, we will discuss sheetmetal bend deduction, bend allowance, K-factor, Y-factor, and sheet metal flat pattern calculations. The neutral axis is an area within the bend where the material goes through no physical change during forming. On the outside of the neutral axis the material is expanding; on the inside of the neutral axis the material is compressing. Along the neutral axis, nothing is changing—no expansion, no compression. In this tutorial, learn the difference between SOLIDWORKS Sheet Metal bend calculations including k-factor, bend allowance, and bend deduction with examples. SOLIDWORKS. 3D CAD . K-Factor is the ratio of the neutral axis to the material thickness.
Neutral Axis is the part of the material that does not change its length during the bending process. 5. K-Factor is a ratio that represents the location of the neutral axis with the thickness of the sheet metal. 6. Bend Allowance is the length of the neutral line between the bend lines, or in other words, the arc length of the bend. It is used .When you bend sheet metal, the neutral axis shifts toward the inside surface of the bend. The ‘K-factor’ is the ratio of the neutral axis location (t) to the material thickness (T), which can be used to to calculate the bend allowance. View the K-factor chart below to calculate the amount of material needed to account for your bend.K Factor in sheet metal bending is a constant used to calculate sheet metal flat length or Flat-pattern. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. During sheet metal part bending, the inside bending surface is compressed, whereas the outer surface is stretched.

In sheet metal design, the K factor is a critical value that influences how the software calculates the bending allowance during the fabrication process. Essentially, the K factor is a ratio that represents the location of the neutral axis (the axis at which the material neither compresses nor stretches during bending) relative to the thickness . During bending, that axis shifts toward the inside of the bend. The k-factor value signifies how far the neutral axis shifts during bending. Specifically, the k-factor value is the neutral axis’ new position after bending, marked “t” in . In flat sheet metal, the neutral axis is evenly located at half the thickness of the sheet metal, but it will move during bending. The position change of the neutral axis is determined by various factors such as the material properties, thickness, bending angle, internal radius, and bending method of the plate. The sheet metal material in this neutral axis in the bending region is neither stretched nor compressed, . During bending, the pink region compresses and the blue region extends. If the neutral sheet metal layer remains undeformed, the length of its arc in the bending region remains the same whether the part is bent or flattened. As a result .
Neutral axis for the beam subjected to bending is a line passing through the cross-section at which the fibres of the beam does not experience any longitudinal stress (compressive or tensile). For the above beam, the dotted line indicates the neutral axis.When designing sheet metal with the Sheet Metal model feature, locate the Material > Bend Calculation option in the dialog.
