Cam 1 rotates about fixed axis B-B and its hyperboloid surface, in which cam groove a is machined, is generated by the revolution of arc b-b of a hyperbola about axis B-B. Follower 3 oscillates about fixed axis A and carries roller 2 which rolls and slides along groove a. Axes A and C of follower and roller rotation intersect and are perpendicular to each other. The plane of oscillation of follower 3 passes through axis B-B.
