Sheet Metal Flat Pattern Layout

It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material.

Sheet metal flat pattern layout.

The value of the k factor should range between 0 0 5. View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections. Importance of the k factor in sheet metal design. Sheet metal cone calculator.

Bend lines must be determined to develop a flat pattern for sheet metal forming. Enter k factor values. Use k factor calculator to calculate k factor values. However to match the other dimensions that are included it would require your manufacturer to work with incorrect or unachievable sheet metal forming factors.

Before a sheet metal part is formed make a flat pattern to show how much material is required in the bend areas at what point the sheet must be inserted into the forming tool or where bend lines are located. Value of bend deduction and flat pattern are shown in result section. Enter flange length internal radius and thickness values. Keep default values in calculator as zero.

Here are the steps to be followed to calculate sheet metal flat length. Therefore it is important to have the value correct in cad software. The flat pattern drawing doesn t always list these factors.
