Sheet Metal Flat Pattern Layout

View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections.

Sheet metal flat pattern layout.

Enter flange length internal radius and thickness values. 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. Therefore it is important to have the value correct in cad software.

Dimensions given on a flat pattern are affected by several bending factors like k factor and bend radius during the 3d modeling stage. Use k factor calculator to calculate k factor values. Importance of the k factor in sheet metal design. The flat pattern drawing doesn t always list these factors.

The value of the k factor should range between 0 0 5. 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. Enter k factor values. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material.

Bend lines must be determined to develop a flat pattern for sheet metal forming. However to match the other dimensions that are included it would require your manufacturer to work with incorrect or unachievable sheet metal forming factors. Keep default values in calculator as zero.
