Creating Forming Tools
Forming tools act as dies that bend, stretch, or otherwise form sheet metal.
To create a forming tool:
Open a new part.
To create the base feature, sketch a profile on the horizontal plane, and extrude the profile above the plane. By default, the horizontal plane is Top.
To create the boss feature, do the following:
Sketch a profile on the horizontal plane centered on the origin.
When applying the forming tool to a sheet metal part, the origin lies where you drop the forming tool.
Dimension the profile, then create the boss feature below the horizontal plane.
The boss feature can be an extrude or a revolve.
Add additional features to the forming tool such as extrudes, revolves, fillets, chamfers, and so on, to shape the forming tool.
NOTES:
The horizontal plane is the stopping surface of the forming tool. Therefore, the entire forming tool must lie below the stopping surface.
The minimum radius of curvature of the forming tool must be greater than the thickness of the sheet metal part to which it will be applied. To find out the minimum radius of curvature of the forming tool, click Tools, Check.
Remove the base feature of the forming tool, so only the form feature from step 3 remains in the model.
TIP: To remove the base feature of the forming tool, select the bottom face of the base feature, open a sketch, and click Convert Entities . Make an Extruded Cut with an End Condition of Through All.
Indicate which faces of the forming tool create openings on sheet metal parts.
Create a positioning sketch, if desired.
Save the part.
