Blank Size Calculator Sheet Metal

Use k factor calculator to calculate k factor values.

Blank size calculator sheet metal.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. A metal sheet is no different than a rectangular bar it is in the steel weight calculator for your convenience mostly. Sheet metal cone calculator. Enter flange length internal radius and thickness values.

Calculate the setback and then subtract it from the sum of two outside dimensions as. With this free online tool we quickly get the sheet metal bend deduction and therefore the sheet metal blank initial flat length from the finished part measurements. A metal tube or pipe is a bit more complex to compute than a round metal bar since we need to know either both the inner and outer diameters or one of the diameters and the thickness of the tubing. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material.

Likewise when you are trying to develop a flat pattern you will have to make a deduction from your desired part size to get the correct flat size. Value of bend deduction and flat pattern are shown in result section. Enter k factor values. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.

For example if the value of k factor for given material thickness and bending machines is known. View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections. As this happens you gain a small amount of total length in your part. I can count the number of bends the number of holes and the number of punches if ran in the turret or take the width x 2 the length x 2 x a multiplier to get the linear inches of laser and build the quote from there.

T the thickness of the sheet or plate 2 000 2 000 i0 125 developing the flat blank length for the above drawn part. Ultimate tensile strength psi. K factor in sheet metal bending is a constant that is used to calculate sheet metal flat length. Cells on the right will output the desired values.

Length of the flat blank in preparation for bending. Therefore using k factor there is no need to calculate sheet metal flat length manually. Keep default values in calculator as zero. The formula for this is sb 43r 1 372t r the radius on the inside curve of the bend.

In a quick second i know the blank size again it is not the real blank size we would use but it is close enough for a quote. Punch edge radius in. Guiding calculation of the measurements of a sheet before folding 1 bend. Sheet metal flat length can be calculated using cad softwares.
