Rotating Cam with a Circular Cam-Follower

To add a 2D-Cam, we must select two elements:

Part  - which becomes the Cam-Part.

Profile/Extrusion - which becomes the Cam-Follower.

Before you can add a 2D-Cam, you must prepare the model with these two elements, and specify their motions.


To model a Cam-Mechanism that is frequently used in packaging machines.
To introduce Inverse-Kinematics.

Summary of this Tutorial

Model a kinematic-chain with three Parts: a Part for the tooling, to which we join a Dyad that includes the Part for the Cam-Follower.
Add a 'Roller' to the Cam-Follower Part.
Model a different kinematic-chain that is the Cam-Part. This is a rotating-Part, or a Cam-Shaft.
Add the 2D-Cam to the Cam-Part, and export the Cam-Coordinates to SolidWorks®.
