Sheet Metal Flat Pattern Layout

Sheet metal cone calculator.

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. The value of the k factor should range between 0 0 5. The flat pattern drawing doesn t always list these factors.

The layout may either be done on the material to be used or on a piece of paper. Value of bend deduction and flat pattern are shown in result section. 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.

Bend lines must be determined to develop a flat pattern for sheet metal forming. Use k factor calculator to calculate k factor values. Enter flange length internal radius and thickness values. The k factor is used to calculate flat patterns because it is related to how much material is stretched during bending.

Enter k factor 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. Therefore it is important to have the value correct in cad software.
