Cam 1 rotates about fixed axis A-A and its globoidal surface, in which cam groove a-a is machined, is generated by the revolution of circular arc b-b of radius r about axis A-A. Follower 2 oscillates about fixed axis B and carries roller 3 which rolls and slides along groove a-a. The plane of oscillation of follower 2 contains the axis of roller 3 and passes through axis A-A.
