Sheet Metal Flat Pattern Layout

The layout may either be done on the material to be used or on a piece of paper.

Sheet metal flat pattern layout.

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

View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections. However to match the other dimensions that are included it would require your manufacturer to work with incorrect or unachievable sheet metal forming factors. Sheet metal cone calculator. 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.

Here are the steps to be followed to calculate sheet metal flat length. Importance of the k factor in sheet metal design. Enter flange length internal radius and thickness values. Bend lines must be determined to develop a flat pattern for sheet metal forming.

Value of bend deduction and flat pattern are shown in result section. Therefore it is important to have the value correct in cad software. Use k factor calculator to calculate k factor values.
