6C: Barrel-Cams & Globoidal-Cams

Barrel Cams and Globoidal Cams

GST-Icon-Add3DCam

Barrel, Cylindrical, and Globoidal Cams are types of 3D-Cams that you can model and design in MechDesigner.

The Cam usually rotates at constant speed. However, this is not necessary. For example, the Cam can be stationary.

You can save the 3D-Cam to a STEP file-type, or export the surface data to SolidWorks, or save the surface data as XYZ coordinates.
