Mechanism | Add Conjugate Cam FB

What is a Conjugate Cam?
A machine design must make sure the Cam-Follower Roller is in continuous contact with the Cam. There are two design principals:
| • | Force Closed Cam - the cam-follower is pushed pulled against the cam with an external force. For example a Spring, Air-Cylinder, Gravity, Magnet, ... |
| • | Body-Closed Cam - add to the same parts in the model a second cam-follower roller and a second cam. The cam-follower rollers are in the same part and thus they move together. The two Cams are also in the same Part. The two Cams in the one Part are called Conjugate-Cams. |
Why do I need to add the Conjugate Cam FB element?
We use a Conjugate-Cam FB when the force analysis is important. We use it to apply the 'Power Source' correctly by switching the contact between the two conjugate-cams.
