Sheet Metal Flat Pattern Layout

Enter k factor values.

Sheet metal flat pattern layout. However to match the other dimensions that are included it would require your manufacturer to work with incorrect or unachievable sheet metal forming factors. Dimensions given on a flat pattern are affected by several bending factors like k factor and bend radius during the 3d modeling stage. Therefore it is important to have the value correct in cad software. Use k factor calculator to calculate k factor values.

Sheet metal cone calculator. Bend lines must be determined to develop a flat pattern for sheet metal forming. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material. Enter flange length internal radius and thickness values.

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. The value of the k factor should range between 0 0 5. Keep default values in calculator as zero. View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections.

Value of bend deduction and flat pattern are shown in result section. Importance of the k factor in sheet metal design. Here are the steps to be followed to calculate sheet metal flat length.
