Sheet Metal Flat Pattern Calculator

For creating a cone from sheet metal or any flat material.

Sheet metal flat pattern calculator. After bending the total length a b is larger than length l. The flat pattern of a cone is an application that calculates the parameters for a development of a right oblique or truncated cone. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Should be subtracted from the flat pattern so the formed part arrives at the desired dimensions.

In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. In the example above it is indicated by a dashed blue line.

Therefore the bend allowance added to the flange lengths. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material. For example when sheet metal of length l is bend. 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.

You can use this sheet metal flat pattern calculator to calculate this increase in length. 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. K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern. Cells on the right will output the desired values.
