BOTTOM CONE DEVELOPMENT Large Radius Small Radius Angle REQUIRED PLATE SIZE LR Chord Length. 60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them. K-factor in sheet metal can be calculated in following steps.
In order to develop the flat pattern we add 457 to 1625 and 2625 to arrive at 4707. The layout may either be done on the material. Calculate the Setback and then subtract it from the sum of two outside dimensions as follows – Where r125 and t125 SB 43 125 1372 1250538 1715225 Then 2000 2000 4000 – 225 3775 This is the length of the flat blank.
It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material. Cut a sample sheet and measure its total flat length and sheet thickness in mm. Shown is a common dimensioning method and calculation of a setback bend deduction sb setback.
