The design of a cam-system must make sure a Follower-Profile (e.g. a Follower-Roller), that is in one kinematic-chain, is continuously in contact with the Cam-Profile, in a different kinematic-chain, at all machine-speeds. There are two(2) designs: A.Force-Closed Cam - an external force pushes or pulls the Follower-Part and Follower-Profile against the Cam-Profile. Example external forces are: Spring, Air-Cylinder, Gravity, Magnet, ... B.Body-Closed (Conjugate) Cam - a design in which two (or more) Follower-Profiles, that are rigidly mounted to one Follower-Part, cannot move away from two (or more) Cam-Profiles, that are rigidly mounted to one Cam-Part, e.g. a Cam-Shaft. Example cam-systems are: Groove-Cams (Track-Cams), Rib-Cams, Globoidal-Cam Indexers, Parallel Indexers. |
To analyze the Contact-Force and Contact Shear-Stress of a Body-Closed Cam, you must add and configure a Conjugate Cam FB. You must also select the Cam-Conjugate FB as the Power-Source for the Follower in the Configure Power Source dialog. |

You need a Conjugate Cam FB to analyze Forces when two 2D-Cams in a kinematic-chain drive two Follower-Profiles that are in a different kinematic-chain.
