The flat pattern of a cone is an application that calculates the parameters for a development of a right oblique or truncated cone.
Sheet metal flat pattern calculator.
For example when sheet metal of length l is bend.
You only have to insert interior angle flange lengths k factor inside radius and material thickness.
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.
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.
Therefore the bend allowance added to the flange lengths.
Should be subtracted from the flat pattern so the formed part arrives at the desired dimensions.
Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness.
You can use this sheet metal flat pattern calculator to calculate this increase in length.
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 creating a cone from sheet metal or any flat material.
The bend allowance is the amount of the neutral axis that bends.
In the example above it is indicated by a dashed blue line.
After bending the total length a b is larger than length l.
In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations.
K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern.
Because a bend deduction can be measured in a physical part it is the most accurate way to calculate a material s stretch.
