The paper aims to analyze the kinematics of the mechanism with rotating cam and oscillating flat face follower. Compared to the knife edge follower, which has a fixed contact point on the follower, the flat face follower presents a mobile contact point with respect to the follower, with complex kinematics. Additionally, the tangency constraint between cam and follower makes difficult the position analysis. The analysis is made in two manners: the geometrical restraint method and the vector-contours method. Both methods offer the same solution, but the actual expressions differ considerably. There are obtained the position angle, the angular velocity and angular acceleration of the follower and the position, velocity and acceleration of the contact point with respect to the follower.
