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

You can save the 3D-Cam to a STEP file-type.

6C1: Barrel-Cam : Oscillating

It is possible to design Barrel-Cams with:

•Cam-Rollers that move along a groove that is cut into the wall of the Barrel (see image)

One Cam-Roller will generate the two Cam-Flanks. To model this 3D-Cam you need only one Cam-Roller.

AND

•Cam-Rollers that move along the sides of a rib that extends out from the wall of the Barrel.

To model a Rib-Cam, you need to add two Cam-Rollers and two 3D-Cams.

6C2: Globoidal-Cam : indexing

These cams are also called Ferguson Drives, or Roller Gear Drives.

6C3: Examine 3D-Cams for Cam-Follower Clearance.
