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.
