Sheet Metal Flat Pattern Calculator

For example when sheet metal of length l is bend.

Sheet metal flat pattern calculator.

You can use this sheet metal flat pattern calculator to calculate this increase in length. Sheet metal cone calculator view the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. The flat pattern of a cone is an application that calculates the parameters for a development of a right oblique or truncated cone.

After bending the total length a b is larger than length l. The bend allowance is the amount of the neutral axis that bends. Cells on the right will output the desired values. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

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. Because a bend deduction can be measured in a physical part it is the most accurate way to calculate a material s stretch. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material. K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern.

For creating a cone from sheet metal or any flat material. Should be subtracted from the flat pattern so the formed part arrives at the desired dimensions. In the example above it is indicated by a dashed blue line. You only have to insert interior angle flange lengths k factor inside radius and material thickness.
