Sheet Bending Calculator Pro vs K factor, Y factor Calculator Usage & Stats
This app is build to calculate bending allowance, bending deduction, Plate or Sheet size required for bending.
This Calculator has both mm and inches setting options.
material k-factor chart and decimal fraction chart available for reference.
this app give easy and faster bending calculation
plate finish size is calculate as per following
finish size = length(L1) + length(L2) - bend deduction.
this app is very useful in daily fabrication activity where bending are done frequently.
this is very handy tool for fabricator.
please consider that k factor is different for different metal normally it taken in between 0.33 to 0.5.

The K factor is the most important and elusive variable of bending because it varies both as a function of the material and according to parameters such as angle and tooling. The K factor is defined as the ratio between the material thickness (T) and the neutral fibre axis (t), i.e. the part of the material that bends without being compressed nor elongated.
Bend allowance is a fundamental parameter to calculate sheet elongation. This is defined as the length of the neutral fibre from the beginning to the end of the arc generated by the bend.
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. After bending the sheet, insert the inner radius, and flanges A and B. Bending angle is 90°.
